Forgotten Realms Conversion Guide

This guide is intended to be a conversion of various monsters and NPCs in order to facilitate proper campaigns set in the Forgotten Realms. There's so many monsters - Phaerimms and Sharns, Fang Dragons and Wemics - that haven't yet been updated to fifth edition and really ought to be.

This isn't a proper sourcebook, homebrew or not. None of the monsters in this guide are of my own creation and reprinting the lore that others have written is impolite at best. Ideally this guide should be used in conjunction with the books that these creatures were originally printed in. In place of lore are my thoughts and justification of the conversion process.

I'm not converting everything word-for-word. There are many design conventions in 5e which do not match those of previous editions, especially concerning damage or condition immunities and resistances, nonabilities, and innate spellcasting. When converting these monsters I'll be removing those abilities where appropriate to make them feel more like 5e monsters and less like obvious conversions of ADnD/3.5e monsters.

Sting. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 3) piercing damage plus 42 (12d6) fire damage.

Alaghi

Alaghi are big, mean, and hairy, but don't have any real distinguishing features. They're a bag of hit points and little else; they don't even have Darkvision. I've given them the bugbear's Brute trait just to bring their damage up to reasonable levels.

Alaghi villages tend towards evil, but hermit alaghi are usually Neutral Good.

Asabi

Asabi are fairly standard reptilian humanoids. Their only distinguishing feature is their jumping ability. The Stingtails are a larger breed, and have poison stings and are immune to enchantment. I decided that lowering their CR was a better call than raising their attributes - Asabi are meant to be squishy minions, and CR 1 is a little high for that in 5e. I would have liked to give the Stingtail higher poison damage, but on top of four attacks 2d6 is about as much as I could justify for a CR 3.

Banedead

The banedead is, appropriately, an undead creature resembling a zombie created from a follower of Bane by Banite clerics. Unlike zombies they are fast and intelligent, like a wight. Their defining trait is their claws, which damage Dexterity like a Shadow damages Strength. I've increased their Strength score (wights got a similar increase upon their conversion to 5e) and the damage of their natural weapons to improve their damage output.

Baneguard

The baneguards are a type of animated skeleton originally developed by priests of Bane. Their most iconic abilities are their ability to fire magic missiles and blink as the spell. I would have tried to convert the blink spell into a proper monster Action, but that spell is like half a page long and it seems like it's easier for everyone involved to just reference the spell. Credit to /u/mclemente26 for using the Phase Spider's Ethereal Jaunt trait.

Ethereal Jaunt. As a bonus action, the baneguard can magically shift from the Material Plane to the Ethereal Plane, or vice versa.

Actions

Longsword. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 5 (1d8 + 1) slashing damage, or 6 (1d10+1) slashing damage if used with two hands to make a melee attack.

Magic Missile (Recharge 5-6). The baneguard fires three darts of magical force. Each dart hits a creature of the baneguard's choice within 120 feet. A dart deals 3 (1d4 + 1) force damage to its target.

Bat, Deep

There are three unique types of bats native to the Realms: bonebats, night hunters, and sinisters.

Bonebats are man-sized skeletal bats whose bites paralyze and which can see invisible creatures.

Night hunters are intelligent, evil, giant bats that give of an aura of fear.

Sinisters are large-sized intelligent bats with the magical ability to paralyze creatures and deflect missiles.

Beast of Malar

The Beast of Malar is a shapechanging beast which switches between panther, bat, and "claw slayer" forms. Each form has its own special abilities, but all forms regenerate, are immune to fear, and resist nonmagical weapons. I've simplified the beast's ability scores so that they are the same in all forms, as usual for shapechangers in 5e. I've also increased the bat form's land speed from 10 feet for the sake of simplicity. Monsters of Faerun, again, doesn't mention languages, so I took a guess.

Beholder Mage

A Beholder mage is a Beholder which can cast Wizard spells, but must put out its central eye to do so. In 3.5e Beholder Mage is a prestige class, but this isn't necessary in 5e. In my opinion the best way to represent the Beholder Mage is as the following monster variant:

Cloaker Lord

A cloaker lord is a more powerful subrace of cloaker. It is mostly identical to an ordinary cloaker, but has the ability to cast spells as a wizard and control other cloakers. I actually had to increase its CR from 7 to 10, unlike most monsters, because the ordinary cloaker's CR increased from 5 to 8. Cloakers were significantly simplified with their conversion to 5e, and I've carried those simplifications into the cloaker lord as well.

I probably would have increased the number of duplicates created with Phatasms to reflect the 3.5e caster level increase, but since the mirror image spell doesn't grant more duplicates as the spell level increases I decided against it; allowing the cloaker lord to create 4 or 5 duplicates would be a good change if you prefer.

After everything it's a little more complicated than I'd like for a 5e monster, but I guess that's just what happens when you throw more special abilities onto an already-complex monster.

Darkenbeast

The darkenbeasts are bat-winged horrors created by Thayan wizards from animals. Their signiture ability is their imprinted spells, which can be cast by a darkenbeast's master. I've simplified the process of casting imprinted spells to make their use by DMs a little easier. I've also removed the ability to dispel magic to revert a darkenbeast, if only for saving space on the statblock.

Darktree

The darktree is an evil treant-like creature. Since they're roughly the same CR in 3.5e, I decided that they would be best represented as a monster variant of the treant, rather than a seperate creature. There are a few sacrifices in faithfulness that are made with this method; darktrees are ordinarily dumber than treants and have more hit points, but I decided those changes were too minor to bother with.

Deepspawn

Deepspawn are beholderlike creatures with six arms: three tentacles and three ending in mouths. Their signature ability is their spawning; a Deepspawn can give birth to any creature it has devoured that is native to the material plane. Deepspawn in 3.0 are large-sized but, for some reason, take up a space 15-by-15 feet. I've just increased their size to huge; I think it makes them cooler, anyways. Their spawning ability is not considered in calculating the CR of the deepspawn; the spawn are independent creatures that grant their own XP, and it would be impossible to balance around it anyways. Deepspawn typically fight halfway submerged in their treasure horde, granting them 1/2 cover.

Demon, Ghour

The Ghour are large, horned demons resembling minotaurs. Their signature abilities are their poisonous breath weapon and stunning roar. The breath weapon originally dealt strength damage, but it seemed simpler to just have it deal poison damage since strength poisons aren't really a thing in 5e. Ghours have spell-like abilities in 3.0, but I decided to remove them like they were removed from Mariliths, Nalfeshnee, and Hezrou.

It was hard to decide on an exact Strength score, since they had 28 Strength in 3e and were stronger than hill giants (25 Strength) and stone giants (27 Strength) but were weaker than glabrezu (31 Strength) and goristro (34 Strength). In 5e hill and stone giants are both stronger than glabrezu, and goristros only have 25 Strength; I went with 23 Strength, but I'm not happy about it.

Greater Doppelganger

The greater doppelganger is similar to an ordinary doppelganger, but also has the ability to devour a humanoid's brain and copy their form exactly, even most class features. This makes the greater doppelganger basically impossible to accurately balance; after all, if one devours a 20th-level wizard, they're a 20th-level wizard now. These are the kind of monsters that just don't make it into 5e, so there's a few sacrifices that need to be made in the way of edition etiquette. I've increased their Dexterity to mimic the Dexterity increase normal Doppelgangers get. I've removed the Magic Item Use trait, as that's pretty much up to DM discretion in 5e anyways. I've taken away the Ambusher and Surprise Attack traits that the normal Doppelganger was granted in 5e, since that isn't really how the Greater Doppelganger functions; they're more focused on deep cover and fighting in shapechanged form than surprise attacks.

Shapechanger. The doppelganger can use its action to polymorph into a Small or Medium humanoid it has seen, or back into its true form. Its statistics, other than its size, are the same in each form. Any equipment it is wearing or carrying isn't transformed. It reverts to its true form if it dies.

Consume Identity. When the doppelganger eats the brain of a Small or Medium humanoid it absorbs the mind of that creature. Once per day, the doppelganger can use its action to polymorph into the creature's form or back into its true form. The doppelganger's statistics are replaced by the statistics of the creature, including personality and alignment. The only exception is divine spells of 2nd-level or higher. The doppelganger assumes the hit points of the new form. It reverts to its true form if it drops to 0 hit points or dies. When it reverts to its true form, the doppelganger returns to the number of hit points it had before it polymorphed. If it reverts as a result of dropping to 0 hit points, any excess damage carries over to its normal form.

The doppelganger can consume up to three identities; if it consumes another, it loses a random identity from those consumed earlier. If the doppelganger commits an act that runs counter to its current form's alignment, it immediately returns to its true form for 1d10 rounds. The doppelganger retains the basic memories of all consumed identities while in its true form, but not deeper memories. Memories from lost identities fade quickly.

Inscrutable. The doppelganger is immune to any effect that would sense its emotions, detect its alignment, or read its thoughts.

Actions

Multiattack. The doppelganger makes three melee attacks.

Slam. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 8 (1d6 + 5) bludgeoning damage.

Rend Shapechanger. Melee Spell Attack: +8 to hit, reach 5 ft., one target. Hit: if the target is in a form other than its true one, it immediately reverts to its true form. If the target is a creature, it takes 55 (10d10) force damage.

Read Thoughts. The doppelganger magically reads the surface thoughts of one creature within 60 feet of it. The effect can penetrate barriers, but 3 feet of wood or dirt, 2 feet of stone, 2 inches of metal, or a thin sheet of lead blocks it. While the target is in range, the doppelganger can continue reading its thoughts, as long as the doppelganger's concentration isn't broken (as if concentrating on a spell). While reading the target's mind, the doppelganger has advantage on Wisdom (Insight) and Charisma (Deception, Intimidation, and Persuasion) checks against the target.

Brown Dragon

The brown dragon is a type of flightless, burrowing chromatic dragon. Their breath weapon is a line of acid. Brown dragons in 3.0 have a handful of magical abilities - which is typical of dragons in that edition - but I've removed them, which is typical of dragons in 5e. Brown dragons were faster than average for a dragon - 60 ft. instead of 40 feet. - but since white dragons also had higher speed in 3.0 but that was removed upon their conversion to 5e, I got rid of it for brown dragons as well. They are roughly as powerful as a blue dragon; in 3.0 they had the same Hit Dice, but brown dragons were larger, although of a lower CR. Their ability scores match those of a blue dragon of the same size category, but not the same age category; since dragons in 5e are mostly organized by size rather than age (a "young" dragon is always large, an "adult" always huge, etc.), I decided to use size rather than age to determine mental abilities (this means, of course, that brown dragons should "age" slightly faster than other dragons). In the end the brown dragon ended up being almost identical to the blue dragon, to the point where I'm not even sure I should have bothered.

I did replace the normal dragon's Wing Attack with a Burrowing Attack that comes without precedence; I just figured that the brown needed a third legendary action option and it the Burrowing Attack gives similar utility - AoE debuff, movement, and damage. But it's not just a cookie-cutter ability; the Burrowing Attack doesn't provoke attacks of opportunity, doesn't deal AoE damage, but deals a little bit more to a single-target.

Burrowing Attack (Costs 2 Actions). The dragon thrashes, burrowing into the ground without provoking opportunity attacks. Each creature within 10 feet of the dragon must succeed on a DC 24 Strength saving throw or be knocked prone. The dragon can then burrow up to half its burrowing speed before rising to the surface and making a bite attack. The dragon has advantage on the attack roll.

Deep Dragon

Deep dragons are the type of dragon most often found in the underdark. They are neither chromatic nor metallic. Their breath weapon is a cone of gas, and they have natural truesight instead of darkvision. They can detect magic, are immune to charm, and have resistance (but not immunity) to cold and fire. As they age they gain the ability to polymorph into a wingless snake and then a humanoid. Ordinarily, a deep dragon would have both by the time they become medium-sized (AKA, a wyrmling in 5e). I decided to give the wyrmling access to the snake form but save the humanoid form for young and older. Ordinarily they are limited to a certain number of uses per day, but that seemed silly to me. Like most dragons in 3.0, deep dragons have a slew of spell-like abilities, of which I've removed most of them. Deep dragons have the same number of Hit Dice as blue and brown dragons, but are smaller; using the same method as I used for brown dragons, they are (again, ugh) almost identical to blue dragons in terms of core statistics but should age slower. Deep dragons are born extraordinarily intelligent but grow in intelligence slower than other dragons; for my conversion, I had the ancient deep dragon equal the green in intelligence and let it start out knowing Undercommon.

Fang Dragon

I've increased the CR and Charisma of the Fang Dragon wholly out of a desire that the dragon should, RAW, be able to learn the traditional Fang Dragon racial spells at a reasonable rate using the Dragons as Innate Spellcasters variant. So, sue me. I might make a more faithful conversion CR-wise in the future, but for this conversion, I was focusing on spell-availability faithfulness. The dragon starts out as powerful as a blue, but begins to taper off to green and eventually ends alongside white, where it is in 3.0 and probably should be.

This - and its Charisma score - are entirely so it meets the minimum requirements for learning new spells. CR 3 and +1 Charisma for shield. CR 9 and +2 for dispel magic. And so on. With these minimums it could still be a CR 18 ancient and learn globe of invulnerability, but that seems unnecessary since it's supposed to equal to the white dragon (CR 20) anyways.

Fang dragons are dumber and less charismatic than average for a dragon, roughly on-par with black dragons. Instead of a breath weapon, a fang dragon's bite drains vitality; in 3.0 this was represented by Constitution drain, but I just went with necrotic damage that can't be healed. Their natural attacks also deal more damage.

Fang Dragon Magic

Fang dragons are especially magical creatures, even among dragons. Unlike most dragon races, Fang wyrmlings can cast spells innately. Almost all fang dragons use the "Dragons as Innate Spellcasters" variant, and are able to cast the following spells 1/day: Wyrmling. shield Young. shield, dispel magic Adult. shield, dispel magic, telekinesis Ancient. shield, dispel magic, telekinesis, globe of invulnerability

Song Dragon

Song dragons are a rare race of dragons that prefer life among humans. They are generally benign, being either chaotic good or neutral. They are neither chromatic nor metallic. Their breath weapon is a cone of electrically-charged gas. They can freely take a unique (female) humanoid form, have a limited-range True Seeing, and can speak any language. They have a series of spell-like abilities, but those can be easily covered by the Dragons and Innate Spellcasters variant and none of them are super race-defining.

A song dragon's alternate form is always an attractive female of 20 to 30 years in age. I thought about changing that and giving them a wider range of possible forms since that seems vaguely sexist, but that's not really my place. The lore is the lore, and my name ain't Ed. However, that seems like a good change to make in your own Forgotten Realms games, and one I might make when I run these dragons myself.

I simplified the dragon's Shapechanger ability significantly to make it easier to use. Since the dragon's Dexterity is already 10 I didn't bother changing it, and changing the Constitution forces so many other changes to the statblock that I didn't think it was worth the space; the Strength decrease is the most important part, since a normal human shouldn't be as strong as a full-sized dragon. This is convenient, since song dragons are not proficient in Strength saves or any Strength-based skills and lose all of their natural attacks.

Song Dragon Magic

Some song dragons are capable of casting a small number of racial spells. Many song dragons use the "Dragons as Innate Spellcasters" variant, and are able to cast the following spells 1/day: Young. darkness, feather fall, light Adult. darkness, feather fall, light, polymorph Ancient. darkness, feather fall, light, polymorph, teleport

Dragonkin

The dragonkin are a race of evil dragon-like humanoids, similar to dragonborn (which they pre-date, to be clear) or half-dragons. They can fly and can detect magic at will. They often grab opponents' magic items and run off with them. I've adjusted their ability scores and lowered their CR so they work better in groups.

Sense Magic. The dragonkin senses magic within 30 feet of it at will. This trait otherwise works like the detect magic spell but isn't itself magical.

Actions

Multiattack. The dragonkin makes two melee attacks.

Pike. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 15 (2d10 + 4) piercing damage.

Claw. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) slashing damage.

Dread Warrior

The Dread Warrior is a type of corporeal undead similar to a wight, created from the body of a powerful fighter. Unlike wights, most dread warriors are under the control of the their creator, and do not create spawn. They are also quite dumb, though they are have some intelligence. I dropped their CR significantly so that they work better as group monsters, and gave them the Bugbear's Brute trait to increase its damage output.

Arctic Dwarf

Arctic Dwarves are a subrace of dwarves that live in cold regions. Unlike most dwarves, they are small-sized, and are immune to cold. I've also included an Arctic Dwarf player race; I'm not as good with races as I am with monsters, so it's not perfect.

I was most unsure of the cold immunity, but since Yuan-ti Purebloods get poison immunity this sort of thing has precedence.

Arctic Dwarf NPCs

When altering a generic NPC to be an arctic dwarf, make the following adjustments to its statblock:

• The dwarf's size is small.
• The dwarf's alignment is lawful neutral.
• The dwarf is resistant to poison damage and immune to cold damage.
• The dwarf has darkvision out to 60 feet.
• The dwarf has advantage on saving throws against poison.

Arctic Dwarf

Arctic dwarves are small but strong, and inured to the effects of cold.

Ability Score Increase. Your Strength score increases by 1.

Small Size. Unlike other dwarves, you are small sized. Your speed is unchanged.

Arctic Immunity. You are immune to cold damage.

Urdunnir

The urdunnir are a magical and long-forgotten race of dwarves. They can walk through stone as if it were air, and can stone shape and shape metal at will. There's no example statblock for an urdunnir NPC, but I figured that your average Urdunnir soldier should be more powerful than any old dwarf. Regardless, I would suggest using NPC statblocks with racial modifications instead of this statblock for most urdunnir; an urdunnir commoner should be a commoner with racial modifications, while a powerful urdunnir warrior might be a champion or warlord. This statblock just describes your average soldier. I used the orog as a power baseline - after all, in 3.0 an orog was an orc subrace just like how the urdunnir is a dwarf subrace.

Urdunnir often ready their action to use Shape Metal or Stone on incoming weapons. If the target fails the save, the attack only deals half damage, and the weapon is useless until repaired.

Ghaunadan

The ghaunadans are shapeshifting ooze-creatures which serve Ghaunadaur, the lord of oozes. Ghaunadans are resistant to bludgeoning weapons and have the whole series of ooze immunities in 3.0; I used the slithering tracker as a base for condition immunities, since it's also an intelligent creature of the ooze type, but removed all immunities that normal oozes don't also have. In ooze form, the ghaunadan can paralyze with its pseudopods or disarm opponents. In humanoid form, they can charm with their gaze. I gave the ghaunadan higher Dexterity to bring its damage up and high Constitution for more hit points, and changed its humanoid form's weapon to a rapier so that it is Dexterity-based. I also gave it the Brute trait to increase its damage output; I'm wary of overusing the trait , but it seems like a better idea than giving it four attacks.

Ghaunadans who operate in human cities usually speak Common as well.

Fog Giant

Weaker relatives of the cloud giants, fog giants lack the cloud giants' magical abilities and are able to hide in fog. They are about as powerful as a stone giant.

Phaerlin Giant

Mutant giants warped by powerful magic, phaerlin giants are a slave race from the underdark. Unlike most giants they can't catch or throw rocks, but they have a frightening presence and are resistant to magic. They are very weak for a true giant.

Oddly, phaerlin giants speak Giant and Common, despite being from the Underdark. I was tempted to give them Undercommon instead of Common, but that's not really my place.

Gibberling

Gibberlings are feral, pitiful creatures similar to goblins. They are fragile and weak. Their main special attack is their gibbering; in 3.0, it only affected creatures with 2 HD or fewer, and even then only had a DC of 10. I did my best to re-engineer the ability to fit with 5e conventions and still be not too powerful. However, even in 3.0 the ability is horribly unspecific on how often the saves have to be made or if success grants immunity.

Additionally, gibberlings got attack bonuses against targets being grappled by other gibberlins (which increased depending on the number of grappling gibberlings); I've just substituted Pack Tactics, which is less fun but simpler and has more precedence. Up to 3 gibberlings could occupy the same space, which is bound to have tons of rule problems in 5e but hey, it probably caused tons of rule problems in 3.0 too. They are immune to mind-affecting effects, but only because vermin are; and since vermin, well, aren't in 5e, I've removed this. They are also vulnerable to light and fire, but in nonstandard ways. I've standardized their Light Vulnerability to fit with that possessed by undead, but I did my best to convert the fire vulnerability as it is intended to work.

All in all, this was a fun one to convert. There aren't too many super-weak monsters in this book. My only gripe is the five special traits for such a squishy monster.

Bunching. Up to 3 gibberlings may occupy the same 5-by-5-foot space.

Fire Fright. When the gibberling takes fire damage, it must succeed on a DC 12 Wisdom saving throw or become frightened of the apparent source of the fire damage for 1 round.

Gibber. At the start of each of the gibberling's turns, each creature within 200 feet of the gibberling that can hear its insane muttering must make a DC 6 Wisdom saving throw. A creature that fails its saving throw has disadvantage on attack rolls until the end of the gibberling's next turn. If a creature makes a saving throw against this ability, it need not make another until the beginning of its next turn.

Pack Tactics. The gibberling has advantage on an attack roll against a creature if at least one of the gibberling's allies is within 5 feet of the creature and the ally isn't incapacitated.

Sunlight Sensitivity. While in sunlight, the gibberling has disadvantage on attack rolls, as well as on Wisdom (Perception) checks that rely on sight.

Actions

Bite. Melee Weapon Attack: +2 to hit, reach 5 ft., one target. Hit: 2 (1d4) piercing damage.

Goblin, Dekanter

Dekanter goblins are mutant goblinoids created by magic, named after the mines of Dekanter from which they hail. They attack with their natural weapons, their horn and claws. Fast Healing isn't really a thing in 5e, so I've replaced it with Regeneration.

Golem, Gemstone

There are three types of gemstone golems: ruby, emerald, and diamond. Unlike typical golems, gemstone golems have average Intelligence and above-average Dexterity. All gemstone golems have Magic Immunity, and each has its own set of special vulnerabilities. I've replaced magic immunity with resistance, as is standard for golems in 5e (unfortunately). Also unfortunate is that special vulnerabilities for golems have been largely removed (the only MM golem which retains one is the flesh golem). Regardless, I've converted them where they made sense.

One small note is that the ruby golem's statblock lists spell-like abilities, but they aren't detailed anywhere. I can only assume this is a mistake and the golem is not supposed to have any.

I gave the diamond golem a +5 racial bonus to its innate spellcasting save DC because it lacked any high mental ability scores. That's not the sort of thing that's usually listed in monster statblock, since it apparently shouldn't matter in 5e, but I couldn't stand not making a note somewhere.

Ruby golems have regeneration and love to grapple things.

Emerald golems have the ability to create teleportation circles to random places.

Diamond golems can fire sunbeams and can use true strike at will. Their melee attacks carry a targeted dispel magic, and they are vulnerable to ki.

Emerald Gates (2/Day). The golem can use its action to create an emerald circle on the ground within 10 feet. The circle is a one-way portal to a random destination that any emerald golem has ever seen on the same plane of existence. The gate normally lasts for 1 minute, but there is a 10% chance that the gate lasts for 1 hour instead.

Immutable Form. The golem is immune to any spell or effect that would alter its form.

Innate Spellcasting. The golem's innate spellcasting ability is Intelligence (spell save DC 17). It can innately cast the following spells, requiring no material components:

At will: true strike
3/day: sunbeam

Ki Vulnerability. When the golem is struck by an unarmed attack by a creature which has the Ki-Empowered Strikes class feature, it takes an additional 7 (2d6) damage.

Magic Resistance. The golem has advantage on saving throws against spells and other magical effects.

Magic Weapons. The golem's weapon attacks are magical.

Actions

Multiattack. The golem makes two melee attacks.

Slam. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 18 (3d8 + 5) bludgeoning damage, and any spell of 9th-level or lower on the target ends.

Sword. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 22 (3d10 + 6) bludgeoning damage.

Thayan Golem

The thayan golem is a weaker type of golem, similar to the true golems but not as powerful. They are created by Thayan wizards and most are sold to Sembian merchants. Unlike true golems, they didn't have magic immunity but just spell resistance and immunity to magic missile. Since golems are already downgraded to Magic Resistance in 5e, I've removed it entirely and just stuck to the magic missile immunity.

I've removed the Magic Weapons trait as well, even though the Thayan golem had magic weapons in 3.0. I figured that since it isn't a true golem and the trait was removed from creatures such as demons upon their conversion, it made sense.

Green Warder

Green warders are plant creatures created by the elves as guards. They have a number of spell-like abilities: sleep once every 1d3 rounds, confusion every 1d6 rounds, and alarm 2/day.

I was a little unhappy with having three different Innate Spellcasting traits, but having recharge-based entries on a list-style Innate Spellcasting trait isn't really something that's done. This way isn't as pretty, but it has more precedence.

Alarm (2/Day). In a natural setting such as a forest or underground, the warder can innately cast the alarm spell, requiring no material components. Its spellcasting ability is Wisdom.

Confusion (Recharge 6). The warder can innately cast confusion (spell save DC 13), requiring no material components. Its spellcasting ability is Wisdom. A creature that succeeds on a saving throw against this trait has advantage on future saving throws against it for 24 hours.

Sleep (Recharge 5-6). The warder can innately cast sleep, requiring no material components. Its spellcasting ability is Wisdom.

Actions

Multiattack. The warder makes two claw attacks.

Claw. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 6 (1d8 + 2) slashing damage.

Groundling

Groundlings are evil dwarven assassins magically transformed to incorporate the features of giant badgers. They have the magic and poison resistance of dwarves, and can grab opponents to drag them beneath the surface. I removed the magic resistance, since dwarves don't get that in 5e. I gave them the dwarf subtype, even though they don't have it in 3.0, because having humanoid racial subtypes on a non-humanoid monster is acceptable in 5e.

Gulguthydra

The gulguthydra is a hybrid creature that combines the attributes of a hydra and an otyugh. It lacks the hydra's regeneration (and, thus, the players don't have to cut off its heads), but it's big and mean and has a bunch of attacks, and has a naueseating stench.

The gulguthydra has significantly more hit points than a hydra with the same amount of heads - 172 for the gulguthydra, 66 for the hydra - in 3.0. However, hydras were given a significant power boost in 5e, and giving the gulguthydra a proportional boost would make them way too powerful. I've left them at CR 12 and given them proportional statistics for that CR.

I can think of no reasonable explanation for the gulguthydra having 15 Charisma, but it is what it is I guess. It's not my place to change stuff like that, though I'm very tempted to lower it to, like, a 6.

Hold Breath. The gulguthydra can hold its breath for 1 hour.

Nauseating Stench. When a creature starts its turn within 60 feet of the gulguthydra or enters the area for the first time on its turn, it must succeed on a DC 19 Constitution saving throw or become poisoned for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a succeess. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the gulguthydra's Nauseating Stench for the next 24 hours.

Actions

Multiattack. The gulguthydra makes eight attacks: six with its bites and two with its tentacles.

Bite. Melee Weapon Attack: +10 to hit, reach 15 ft., one target. Hit: 11 (1d10 + 6) piercing damage.

Tentacle. Melee Weapon Attack: +10 to hit, reach 15 ft., one target. Hit: 10 (1d8 + 6) bludgeoning damage plus 4 (1d8) piercing damage. If the target is Large or smaller, it is grappled (escape DC 18) and restrained until the grapple ends. The gulguthydra has two tentacles, each of which can grapple one target.

Hybsil

Hybsils are small fey creatures similar to centaurs but with the lower body of an antelope instead of a horse. They have a small list of spell-like abilities (which, thankfully, work normally), can see invisible creatures, and are immune to poison.

Ibrandlin

The ibrandlin is a gigantic but relatively low-CR dragon in 3.0. It usually fights rearing up on its tail, so it can use all four of its claws in combat. Its hit points and damage are quite high for its CR even in 3.0 (supposedly, their low AC and lack of certain special abilities common to true dragons makes up for this), so I had to adjust them significantly to make things play nice in 5e. Their hit points were relatively appropriate for a CR 5 monster in 5e, but their damage is way too high with a bite and four claws. In 3.0 they are every bit as physically strong as a red dragon of the same size (35 Strength), and I've decided to (almost) keep this true in my conversion. In order to keep attack bonuses in check, though, I've removed the ibrandlin's proficiency in its own attacks, like a purple worm. I've also removed their Magic Resistance, since not even true dragons have it in 5e.

An ibrandlin's breath weapon is extremely weak compared to that of a true dragon, but can be used in place of a bite attack in a full attack. An ibrandlin's most unique attack is its ability to jump and land on opponents, pinning them to the ground. This kind of attack is difficult to replicate in 5e due to the edition's dislike for creatures sharing the same space, but I decided to just ignore all that and hope no-one complains.

I was a bite unsure about giving the ibrandlin only 2 legendary actions (since that isn't really something that's done in 5e), but it was the easiest way to get its damage down while retaining faithfulness to the original creature.

Actions

Multiattack. The ibrandlin makes three attacks: one with its bite and two with its claws. It can use its Fire Breath in place of its bite attack.

Bite. Melee Weapon Attack: +8 to hit, reach 15 ft., one target. Hit: 17 (2d8 + 8) piercing damage.

Claw. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 12 (1d8 + 8) slashing damage.

Fire Breath (Recharge 6). The ibrandlin exhales fire in a 30-foot cone. Each creature in that area must make a DC 14 Dexterity saving throw, taking 10 (3d6) fire damage on a failed save, or half as much damage on a successful one.

Pin. The ibrandlin jumps into the air, attempting to land on opponents and pin them to the ground. The ibrandlin must use its normal movement to do so, but can end its turn in an occupied space. All creatures in the ibrandlin's space when it ends its turn must succeed on a DC 16 Strength or Dexterity saving throw or become restrained. A restrained creature may use its action to repeat the save, freeing itself on a success. However, a creature that uses its action to take the Attack action or repeat the save takes 14 (4d6) bludgeoning damage.

Legendary Actions

The ibrandlin can take 2 legendary actions, choosing from the options below. Only one legendary action can be used at a time and only at the end of another creature's turn. The ibrandlin regains spent legendary actions at the start of its turn.

Claw. The ibrandlin makes one attack with its claw.

Deep Breath. The ibrandlin automatically recharges its Fire Breath.

Ice Serpent

Ice serpents are elemental creatures that appear to snakes made of frigid air. I decided to go with another template, to be added to the Giant Constrictor Snake. Though the size is wrong - Ice Serpents are Large, and Giant Constrictor Snakes are Huge - the normal constrictor snake is just too low-CR. I also decided to let it retain the Giant Constrictor Snake's bite attack, even though Ice Serpents normally do not have one.

Malaugrym

Malaugryms are perfect shapeshifters from some unknown plane, who enter Toril through the Plane of Shadow. Their original Alternate Form trait is ridiculously overpowered (like, CR 4 monster shapechanging into any monster with 20 or fewer HD overpowered), so for this conversion I'll be basing it off of the 3.5e conversion which uses a more standardized Change Shape special quality instead.

---

Shapechanger. The malaugrym can use its action to polymorph into any creature of less than deity status, or back into its true form. Most malaugryms have one or two forms they prefer. Its statistics, other than its size, are the same in each form. Any equipment it is wearing or carrying is absorbed or borne by the new form (the malaugrym's choice). It reverts to its true form if it dies.

Magic Resistance. The malaugrym has advantage on saving throws against spells and other magical effects.

Silver Anathema. The malaugrym cannot heal damage caused by silvered weapons naturally.

Actions

Multiattack. The malaugrym attacks three times with its tentacles.

Tentacle. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) bludgeoning damage.

Meazel

Meazels are evil humanoid creatures slightly smaller than humans. They carry a vicious skin disease that makes them appear hideous but can be fatal to others. In 3.0 they have the Sneak Attack and Evasion (which rogues get at level 2, not 7) abilities of the rogue; I've removed Evasion and opted not to grant them Cunning Action, for simplicity's sake.

Their CR ended up being a lot lower - from 4 to 1/2 - but I think that's okay; I don't really get why it was that high in the first place. For comparison, the meazel gets two attacks - 1d4 claws with no damage bonus - each of which might get an additional 3d6 damage from Sneak Attack (there's no per-turn limit in 3e), for 26 damage/round. The ibrandlin, which is one point of CR higher, gets four claws and a bite, for 86 damage/round. Meazel has 18 hp, ibrandlin has 135. Meazel has +4 to hit, ibrandlin has +18. I don't get it.

Myrlochar

The myrlochar is a demonic spider creature similar to a bebilith but not nearly as powerful. Their main attack is their bite, which can permanently drain hit points and either paralyze targets or reverse gravity for them. They can levitate, and move in complete silence.

I've removed their permanent hit point drain, since that's just not the sort of thing that happens in 5e, and had the target's maximum hit points decrease by 1 automatically with every attack, otherwise working identically to that of a wraith. I replaced their levitation with a hovering fly speed since that's more standardized and easily understood, and removed their ability to cast hold monster with their bite to keep the ability simple (and the reverse gravity effect is just so much more fun, anyways).

Nishruu

Nishruu are weird gaseous creatures which subsist on magical energy. They are interesting in that they have no abilities which deal damage; their only method of interacting with "opponents" is to drain their magical items and prepared spells. But it feels wrong to try to split up Absorb Magic so it has to be actively used.

Nyth

Nyths are glowing balls of light that resemble will o' wisps. They can turn invisible like a will o' wisp, and can fire magic missiles, reflect such missiles fires at them, and absorb fire and lightning damage.

Even though will o' wisps were changed from aberrations to undead in 5e, I decided to leave the Nyth as an aberration as one more way to differentiate the two. Nyths also aren't incorporeal, though neither were will o' wisps in 3.0. In 3.0 will o' wisps were one CR higher than nyths (6 and 5, respectively). Since will o' wisps were nerfed to CR 2 in 5e, I've decided to also set the Nyth at CR 2.

Phaerimm

Phaerimms are evil, sorcerous aberrations that look like 10-foot-long windsocks. Their tail stingers are poisonous, they are resistant to magic, have truesight out to 120 feet, fly as the spell, and don't require any components for their spells. I've removed the ignoring of components, since it just isn't really necessary in 5e and overcomplicates the ability. I removed their bite attack because it was a secondary attack anyways. Phaerimm disdain physical combat, only attacking with their claws as a last resort. However, it is acceptable for younger phaerimms who lack potent magical abilities to carry swords for self-defense.

Planetouched, Fey'ri

The Fey'ri, or daemonfey, are a variant of the tiefling, an elf with distant demonic blood. They have all normal elf traits, can change shape at will like an incubus, and have a number of demonic abilities.

I kept the fey'ri's Constitution penalty on the statblock because, even though races don't usually have ability score penalties in 5e, I believe that that's a game design principle and not a worldbuilding rule. Elves are frailer than other races, just like in every single other relevant previous edition, but PC elves don't have a penalty because that's no fun.

I thought about going with a more powerful NPC to represent the average fey'ri, like what was done with the tanarukk, but instead decided to make two different NPC statblocks - a CR 1/2 "1st-level" fey'ri, and a CR X fey'ri sorcerer - as well as a template which can be applied to a generic NPC statblock, a toned-down PC race, and a racial feat to restore some of the abilities that needed to be cut.

Shapechanger. The fey'ri can use its action to polymorph into a Small or Medium humanoid, or back into its true form. Without wings, the fey'ri loses its flying speed. Other than its size and speed, its statistics are the same in each form. Any equipment it is wearing or carrying isn't transformed. It reverts to its true form if it dies.

Demonic Abilities. The fey'ri has up to four random traits from the Demonic Abilities table.

Fey Ancestry. The fey'ri has advantage on saving throws against being charmed, and magic can't put the fey'ri to sleep.

Spellcasting. The fey'ri is an 10th-level spellcaster. Its spellcasting ability is Charisma (spell save DC 15, +7 to hit with spell attacks). It has the following sorcerer spells prepared:

Cantrips: fire bolt, friends, light, mage hand, minor illusion, prestidigitation
1st level (4 slots): detect magic, mage armour, magic missile, shield
2nd level (3 slots): hold person, invisibility, misty step
3rd level (3 slots): dispel magic, fireball
4th level (3 slots): confusion, dimension door
5th level (2 slots): cone of cold, telekinesis

Actions

Multiattack. The fey'ri makes two weapon attacks.

Rapier. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) piercing damage.

Shortbow. Ranged Weapon Attack: +6 to hit, range 80/320 ft., one target. Hit: 6 (1d6 + 3) piercing damage.

Demonic Abilities

A fey'ri NPC has up to four of the following special traits, while a fey'ri PC has one.

• charm person 1/day
• clairvoyance 1/day
• darkness 1/day
• detect thoughts 1/day
• resistance to fire damage
• resistance to lightning damage
• resistance to poison damage and advantage on saving throws against poison.

The following traits cost two traits. These traits cannot be chosen by a fey'ri PC at 1st-level. For example, a Fey'ri NPC could have up to two of these traits, or one of these traits and up to two from the above list. Having one of these traits might increase the fey'ri's CR.

• blight 1/day
• dimension door 1/day
• resistance to bludgeoning, piercing, and slashing damage from nonmagical weapons

If you're unsure about the balance of any of these options, feel free to limit their availability to PC fey'ri; these options are mostly meant for NPCs and to reflect how fey'ri work in 3.0. For example, letting a level 4 PC to take the fey'ri racial feat and cast blight 1/day would be horribly unbalanced.

Racial Feat: Daemonfey Magic

Prerequisite: Elf (fey'ri) You gain the following benefits:

• You can use your action to polymorph into a Small or Medium humanoid, or back into your true form. If your new form does not have wings, you lose your flying speed. Other than your size and speed, your statistics are the same in each form. Any equipment you are wearing or carrying isn't transformed. You revert to your true form if you die.
• You grow bat wings. You have a flying speed of 40 feet. To use this speed, you can't be wearing medium or heavy armour.
• You choose 2 additional traits from the Demonic Abilities list.

Shalarin

The shalarin are a race of merfolk-like aquatic creatures. They don't have any special abilities, but they do have their own unique types of armour: silverweave and pearl. Aside from that, I'm not really sure what the difference between a merfolk and a shalarin is supposed to be.

Independent Action. The sharn can take two actions on its turn. The sharn can only take the Multiattack action once per turn, and can only cast one spell from each of its spellcasting classes per turn.

Magic Resistance. The sharn has advantage on saving throws against spells and other magical effects.

Cleric Spellcasting. The sharn is an 5th-level spellcaster. Its spellcasting ability is Wisdom (spell save DC 15, +7 to hit with spell attacks). It has the following cleric spells prepared:

Cantrips: sacred flame, spare the dying, thaumaturgy
1st level (3 slots): cure wounds, guiding bolt, inflict wounds

2nd level (2 slots): invisibility, mirror image
3rd level (2 slots): dispel magic, fireball

Actions

Multiattack. The sharn makes twelve attacks: three with its bites and nine with its claws.

Bite. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 12 (2d6 + 5) piercing damage.

Claw. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 3 (1d6) slashing damage.

Create Hex Portals. The sharn creates up to three miniature hexagonal portals within 20 feet of itself through which it can see, cast spells, and make melee attacks. The sharn can use its bonus action to move any number of the portals up to 20 feet. If a portal is ever more than 100 feet away from the sharn, it disappears.

Siv

Sivs are frog-headed swamp-dwelling humanoids that often take levels as monks. They can walk on water and are resistant to cold. I've included a low-CR base siv and higher-CR siv meant to imitate a mid-level monk.

Amphibious. The siv can breathe air and water.

Unarmoured Defence. While the siv is wearing no armour and wielding no shield, its AC includes its Wisdom modifier.

Water Walking. The siv can walk on water.

Actions

Multiattack. The siv makes three siangham attacks or three sling attacks.

Siangham. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) piercing damage.

Sling. Ranged Weapon Attack: +6 to hit, range 30/120 ft., one target. Hit: 6 (1d4 + 4) bludgeoning damage.

Spectral Panther

Spectral panthers are mysterious creatures which radiate a fear aura and can become incorporeal three times per day.

Spider, Sword

A sword spider's signature attack is their ability to jump into the air and stab down with their legs, which are as sharp as blades. I had to increase their CR a couple points, because 7 damage is a lot of damage when it's getting multiplied by 8.

I decided to have Impalement act as a single source of damage, since that's simpler. Instead of having the amount of legs hit depend on size, I set it to a flat 8d6 + 4 damage: more than four individual legs, but less than it could deal with Multiattack against multiple creatures.

Spider Climb. The spider can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.

Web Sense. While in contact with a web, the spider knows the exact location of any other creature in contact with the same web.

Web Walker. The spider ignores movement restrictions caused by webbing.

Actions

Multiattack. The spider makes nine attacks: one with its bite and eight with its legs. The spider can only make up to four leg attacks against any single creature.

Bite. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) piercing damage, and the target must make a DC 13 Constitution saving throw, taking 9 (2d8) poison damage on a failed save, or half as much damage on a successful one. If the poison damage reduces the target to 0 hit points, the target is stable but poisoned for 1 hour, even after regaining hit points, and is paralyzed while poisoned in this way.

Leg. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 7 (1d6 + 4) slashing damage.

Impale. If the spider jumps at least 10 feet as part of its movement, it can then use this action to impale a creature within 5 feet with its legs. The creature must make a DC 15 Dexterity saving throw, taking 32 (8d6 + 4) piercing damage on a failed save, or half as much damage on a successful one.

Stinger

The stingers are centaur-like creatures with a red-skinned humanoid upper body and the lower body of a scorpion. They have a poisonous stinger, and their most interesting ability is their Bolthole Magic, which allows them to magically move up or down 20 feet to an open space as long as their is at least a foot of dirt in the intervening space.

Tall Mouther

The tall mouther is the natural predator of halflings. It appears as a large, gorilla-like head supported by a whirlwind of blue-furred arms.

Tomb Tapper

The tomb tappers are faceless netherese constructs which collect magic items. They are blind and see using sonar. They have a couple stone-related spell-like abilities, and can detect magic at will.

Unicorn, Black

Black unicorns are unicorns corrupted by the evil influence of the Red Wizards. In 3.0 they are very similar to regular unicorns, just with a few abilities reversed here and there. However, the 5e unicorn is a little more complex than the 3.0 one, so I had to take some creative liberties.

Wemic

The wemic is a centauroid creature with the upper body of a human and the lower body of a lion. They didn't have any special abilities, so I gave them the lion's Keen Smell, Pounce, and Running Leap traits. I reduced their Strength score to mirror the Lion's strength decrease in 5e. I changed their main weapon to a spear to give them some amount of ranged combat ability.

Zombie, Tyrantfog

These wretched undead are the remains of worshipers of evil deities struck down by the raw power of another evil deity. Their claws carry a minor disease; like with the meazel, I made it identical to the diseased rat's disease. The zombie's main ability is their Sickening Cloud, which in 3e causes a small amount of Con damage; for the conversion, I just had it deal some poison damage.

Beast of Xvim

The beasts of Xvim are manifestations of the god Iyachtu Xvim, ordinary animals transformed by his will. Most are black-furred, and their eyes and mouths glow green.

I decided the best way to represent the beasts of Xvim are as a template, like a Half-Dragon.

Curst

Cursts are undead humanoids trapped under a curse that will not let them die. They are resistant to magic and turning, and are immune to cold and fire. In 3e Cursts regenerated one hit point per hour, but that kind of thing isn't what Regeneration is used for in 5e often. I replaced it with a trait based on the Naga's Rejuvenation. I've also removed the magic resistance, since it was removed from most creatures upon conversion to 5e and I don't see a particular reason to keep it here.

Even though the Curst was a template in 3e, since the very similar Revenant was changed to single creature I figured that the Curst would work best that way as well. I'm basing the statblock mostly off of the 5th-level Fighter example Curst.

Ghost

Monsters of Faerun comes with a handful of extra special attacks that ghosts might have access to. None of these special abilities normally affect a ghost's challenge rating, though giving them too many might. A ghost might not have the Withering Touch, Horrifying Visage, or Possession action options, especially if it has one of the action options from this list. Some ghosts might have immunity to one or more additional damage types, usually acid, fire, or lightning.

Chill Ray. Ranged Spell Attack: +5 to hit, range 90 ft., one target. Hit: 14 (4d6) necrotic damage, and the target's speed is reduced by 10 feet until the start of the ghost's next turn.

Deathsong (1/Day). The ghost begins to sing a hollow dirge for 1 minute. The ghost must concentrate on this ability as if concentrating on a spell. When the ghost uses this action and at the start of each of its turns until it stops singing, all living creatures within 90 feet must succeed on a DC 13 Wisdom saving throw or become frightened until the singing ends. A frightened creature drops what it is holding and must take the Dash action and move away from the ghost by the safest available route on each of its turns.

Life Drain. Melee Spell Attack: +5 to hit, reach 5 ft., one target. Hit: 9 (2d8) necrotic damage. The target must succeed on a DC 13 Constitution saving throw or its hit point maximum is reduced by an amount equal to the damage taken. This reduction lasts until the target finishes a long rest. The target dies if this effect reduces its hit point maximum to 0.

Vengeful Strike. Melee Spell Attack: +5 to hit, reach 5 ft., one target. Hit: 17 (4d6 + 3) necrotic damage. If the target is the ghost's killer, its hit point maximum is reduced by an amount equal to the damage taken. This reduction can only be removed by a remove curse spell or similar effect.

Debilitating Touch. Melee Spell Attack: +5 to hit, reach 5 ft., one target. Hit: 10 (3d6) necrotic damage, and the target must succeed on a DC 13 Constitution saving throw or become poisoned for 1 minute. A creature can repeat the save at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the ghost's Debilitating Touch for the next 24 hours.

Antimagic Cone. The doomsphere creates an area of antimagic, as in the antimagic field spell, in a 150-foot cone. At the start of each of its turns, the doomsphere decides which way the cone faces and whether the cone is active. The area works against the doomsphere's own eye rays.

Ethereal Sight. The doomsphere can see 60 feet into the Ethereal Plane when it is on the Material Plane, and vice versa.

Incorporeal Movement. The doomsphere can move through other creatures and objects as if they were difficult terrain. It takes 5 (1d10) force damage if it ends its turn inside an object.

Actions

Withering Bite. Melee Spell Attack: +7 to hit, reach 5 ft., one target. Hit: 17 (4d6 + 3) necrotic damage.

2. Slowing Ray. The targeted creature must succeed on a DC 16 Dexterity saving throw. On a failed save, the target's speed is halved for 1 minute. In addition, the creature can't take reactions, and it can take either an action or a bonus action on its turn, not both. The creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

10. Blighting Ray. The targeted creature must make a DC 16 Constitution saving throw. If the target is good-aligned, it takes 45 (10d8) necrotic damage and is poisoned for 1 minute on a failed save, or half as much damage on a successful one.

A neutral-aligned creature takes half damage and is not poisoned on a failed save and takes no damage on a successful save. An evil-aligned creature is unaffected by the ray.
