The Atlantean Compendium Part 2

# Atlantean Treasury

#### Atlantean Trident

*Weapon (Trident), Uncommon*

This gold-plated trident is embedded with a number of deep sea sapphires and is used commonly by Atlanteans. While holding the Atlantean Trident you gain a swimming speed of 35 feet. You gain a +1 bonus to attack rolls and damage rolls made with the Atlantean Trident, and if you throw the Atlantean Trident underwater, it immediately flies back to your hand after you have made the attack.

#### Abyssal Piercer
*Rapier, Uncommon*

This rapier has a deep cobalt blade that is practically black, with connected pieces of abyssal chitin as its guard. You gain a +1 bonus to attack rolls and damage rolls made with this weapon, and once per turn, you can choose to make an attack with disadvantage in an attempt to make a Stinging Strike. On a hit, the target takes an additional 1d8 poison damage and must succeed on a DC13 Constitution saving throw or be Poisoned until the start of your next turn.

**Curse**. The abyssal poison that is embedded into the blade of this weapon contains the vengeful spirits of the slain aberrations that were used to make this weapon, and they often strike back. If you miss your Stinging Strike with this weapon, the poison of the weapon siphons away one of your hit dice. If you have no hit dice remaining, you gain a level of exhaustion.

<br>

#### Angler's Folly
*Wondrous Item, Uncommon*

Used as a last ditch effort by Leviathanguards when they are getting overwhelmed by aberrations, this 4 inch wide glass sphere has a pearlescent sheen to it that always seems to faintly glow even in the deepest depths of the ocean.

As an action you can toss the Angler’s Folly to a point within 30 feet of you, where it immediately glows a soft but brilliant iridescent light out to 60 feet, providing bright light out to 60 feet for 1 minute. Creatures of your choice within 60 feet of the sphere that can see the light must succeed on a DC15 Wisdom saving throw or become charmed by the light for 1 minute. Aberrations with a swimming speed have disadvantage on this saving throw. While charmed, a creature must spend their turn dashing to get closer to the light, and do nothing else. A creature remakes the initial saving throw at the end of each of their turns and upon taking damage, ending this effect upon success and becoming immune to its effects for 24 hours.

Once the Angler’s Folly has been used, the magic fades from it and it becomes a mundane glass sphere.

#### Anklet of the Barracuda
*Wondrous Item, Uncommon*

Used by both hunters and Leviathanguards, this simple seaweed anklet is adorned with silver and aquamarine statuettes of barracudas. Once per turn, before making an attack, provided you are underwater, you can propel yourself forward 30 feet towards the target of your attack.

<br>

#### Cuttlefish Leathers
*Armor (Leather), Very rare*

This smooth leather armor seems to warp and shift in color depending on your surroundings and mood. While wearing the Cuttlefish Leathers, if you have moved no more than 10 feet during your turn, when you end your turn you become Invisible. This invisibility lasts until the end of your next turn or until you make an attack, force a creature to make a saving throw, or move more than 10 feet on a turn.

#### Cloak of the Jellyfish
*Wondrous Item, Uncommon*

Used often by the Leviathanguard, this translucent cloak looks akin to that of a jellyfish and faintly moves on its own as if affected by invisible underwater currents. If a creature grapples you, you are swallowed by a creature, or a creature makes a Shove attack against you while you are wearing this cloak, as a reaction you can activate the paralytic and stinging properties of the cloak, where the creature must succeed on a DC14 Constitution saving throw or take 3d6 poison damage and be paralyzed until the end of your next turn, only taking half damage on success. Once you have used this feature you cannot use it again until the next dawn

<br>

#### Coral Wreath Circlet
*Wondrous Item, Rare (requires attunement by a Spellcaster)*

This circlet is made of a multicolored miniature coral reef, with a variety of living Coral that adorn it. While attuned to the Coral Wreath circlet you can use it as a spellcasting focus. The Coral Wreath Circlet has 10 charges, regains 1d10 + 5 charges at dawn, and you can expend charges to cast the following spells; *Coral Shard* (1), *Coral Wreath* (1), and *Rampant Coral Growth* (4). Additionally, when you are hit with a melee attack, as a reaction, you cause coral growths to sprout from your circlet to protect you, where you gain 5 temporary hit points per charge expended from this reaction that immediately take the triggering damage and fade at the end of the turn. You cannot use this reaction when you have taken psychic damage.

Furthermore whenever you cast a spell with the word Coral in its name, you gain 5 temporary hit points and you have a +1 bonus to your AC while you have these temporary hit points (These temporary hit points are added to the temporary hit points given in Coral Wreath).

<br>

#### Heart of the Kraken
*Wondrous Item, Uncommon*

This twine necklace appears to be made of broken kraken teeth with a small jade sculpture of twisting tentacles; a common symbol of Zhragthonu, the Krakenfather. While wearing this necklace, as an action you can fill your lungs with seawater and spew out the seawater which erupts into a 30 foot cone of crackling lightning. Each creature within this area must succeed on a DC13 Dexterity saving throw or take 6d6 Lightning damage, halved upon success. Once you have used this feature you cannot use it again until the next dawn.

#### Leviathanguard Plate

*Armor (Splint), Rare (requires attunement)*

This bulky and jagged suit of armor is made of crimson chitinous shells of deep sea aberrations in combination with that of giant crabs and is usually worn by the Leviathanguard. While wearing this armor you gain a +1 bonus to your AC and you can cast the spells *Utaeli’s Crab Claw* and *Utaeli’s Crab Carapace* without components through the innate magic of the armor. Once you have cast one of these spells, you cannot cast that spell again until the next dawn.

<br>

#### Royal Atlantean Plate

*Armor (Half Plate or Plate), Uncommon*

This royal armor is made of an alloy of Undersea Thulium and treated platinum with pearlescent filigree and decorative embeds of silver seashells and pearls. This armor does not inhibit your ability to swim, is effectively weightless while underwater, and if you are submerged in seawater while wearing this armor, you gain a +1 bonus to your AC as the filigree and pearls faintly glow.

\columnbreak

#### Redirection Trident
*Weapon (Trident), Rare (requires attunement)*

This deep cerulean and black trident is embedded with iridescent pearls that thrum with arcane energy that lead to three twisted prongs, and it is commonly used by Atlanteans when facing krakens or lightning elementals. This trident has 4 charges, and regains 1d4 +2 charges at dawn. You gain a +1 bonus to attack rolls and damage rolls made with this weapon and when you take lightning, thunder, or force damage, you can expend a charge as a reaction to gain resistance to that instance of damage and redirect it towards a target you can see within 60 feet of you. The target must then succeed on a DC14 Dexterity saving throw or take 3d10 of the damage type that triggered this reaction.

#### Sekolah's Ire
*Wondrous Item, Rare (requires attunement)*

This jagged and mangled medallion is composed of bloodied shark teeth bound by rusted iron and gold. While attuned to Sekolah's Ire, you have advantage on attack rolls against creatures who are missing more than half of their total hit points and you critically strike creatures who have half of their total hit points on a roll of 19 or 20. Additionally, as an action you can cast the spell *Bloodsense*, without requiring Components. Once you have used this feature you cannot use it again until the next dawn or until you have reduced a creature to zero hit points.

**Curse.** The bloodthirsty nature of Sekolah’s Ire brings about frenzy and primal urges near blood. Once you have attuned to Sekolah’s Ire, your eyes and teeth noticeably change to become more shark-like, and you cannot willingly unattune from Sekolah’s Ire. Furthermore, whenever you reduce a creature to zero hit points, you must succeed on a Wisdom saving throw of 10 or spend your next turn eating the flesh of the slain creature, if possible.

<br>

#### Sekolah's Ravager
*Club, Uncommon*

This club has been fashioned with a multitude of razor sharp and jagged shark teeth, that always seem to have traces of blood on their surface. Sekolah’s Ravager deals an additional 1d6 slashing damage on hit, and when you critically strike a creature with this weapon, it rips open a magical wound. A creature who is wounded takes 2d6 necrotic damage at the start each of their turns for 1 minute, or until magically healed or a Wisdom (Medicine) check of 14 is made to staunch the bleeding as an action.

<br>

#### Vortex Guard
*Wondrous Item, Rare (requires attunement)*

These cobalt and gold bracers have ancient aquan and abyssal etching on them, and water seems to naturally form vortexes and flow easier when around them. While attuned to these bracers, you gain a +1 bonus to your AC while submerged in seawater and you do not suffer disadvantage on weapon attack rolls made while underwater due to the weapon being used.

When you are targeted by a ranged weapon attack while underwater, you can slam the Vortex Guard bracers together to create a swirling vortex to slow and displace the projectile as a reaction, forcing your attacker to roll an additional d20 and take the lower result.

\columnbreak

With a regal plated but functional armor and an equally regal presence, the Royal Atlantean Guard are as their name suggests; upholding law, order, and the will of the Atlanteans where they may go. Although their weaponry may change, most Atlantean Guards carry magically imbued Tridents that return to their grasp after being thrown, as Tridents are tried and true for the Atlantean people.

**Steadfast.** The strength of the Atlantean Guard comes not from themselves, but from their ability to gather and rally their own to construct impenetrable barricades and squadrons. Atlantean pride runs deep within a Royal Atlantean Guard's blood, and they are very rarely seen alone; instead surrounded by brothers and sisters in arms.

Typically clad in monstrous red chitin and shells of massive fallen aberrations and deep sea monstrosities, the Leviathanguard are specially trained to fight against the horrors of the deep.

**Trinketed Armor.** The armor, shield, and spear of the Leviathanguard Hunters are typically the spoils of their victories; using a variety of aberration and monster parts such as mokorth carpace lining in their shields, dragonturtle shell pauldrons, giant lobster plating, chuul leather straps, etcetera. Not only does this allow the Leviathanguard Hunter to utilize the resistances of their stronger foes, but it makes them look incredibly intimidating and dangerous, especially to the monsters they are trained to battle.

**Trained to Fight.** Unlike other guards or soldiers Leviathanguard Hunters, like their name suggests, are trained to specifically fight aberrations and deep sea leviathans. Their fighting style, mannerisms, and drills all have this aspect in mind and it is said that the mind of a Leviathanguard is so sharp that they can overcome mental enslavement caused by Aboleths.

Wavedancers are an elite group of Atlanteans that have mastered the flow of the currents and waves of the sea, and can now call upon that connection in battle to summon impossibly sharp slashes of water and dance around their enemies. Because this fighting style is so versatile, Wavedancers can be used as scouts, assassins, guards, or Leviathanguards. Regardless of their station, their grace is unrivaled and they are a deadly force to be reckoned with.

Similar to many of the forces that are in play above the waters, Atlanteans also have their own unique scouts to quickly traverse coral reefs, kelp forests, and even lagoons where budding civilizations may be putting themselves at risk from being too close to Atlantean strongholds.

To traverse quickly through these areas to spread word and gain information, Atlanteans have Seadragon Scouts who, like their name suggests, ride atop Giant Seadragons who can hide and sneak around with the same skill as the rider.

\columnbreak

**Covered In Kelp.** At first glance, one might assume that a Seadragon Scout has slipped and fallen in aquatic detritus, as they are covered head to toe in kelp, coral, and other flora of the deep sea; but this works as a kind of natural camouflage in imitation to the Seadragon. With these specialized armors, Seadragon Scouts are able to blend into their surroundings much easier, and are even able to hide on top of their Giant Seadragons as they both blend into the background. Although not as common, some of these scouts have donned Cuttlefish Leathers and have Cuttlefish Leather Barding for their mounts to allow for even greater stealth, but usually this is not as needed as a Seadragon Scout's only job is to hide, scout, and travel; only resorting to combat if absolutely necesssary.

> ### Reactions
> ***Coral Barrier.*** When a creature within 10 feet of the Coralshaper takes damage from a weapon attack (they can target themself), they can coat the target in protective coral, reducing the damage taken by 1d10 + 3.

Coralshapers, as their name implies, have mastered the druidic art of accelerating the growth of nearby coral; in both offensive and defensive capabilites. Coralshapers are a powerful force in combat as their connection with the sea allowing them to mitigate damage through coral barriers, heal their allies, and throw razor sharp shards of coral towards their enemies.

\columnbreak

**Architects and Combatants.** Despite their effective combat capabilites, they are also prized as architects within Atlantean communities, as coral growths can be quickly fashioned into walls and buildings with varied colors and designs that match the aesthetic taste of the Coralshaper.

**Masters of the Sea.** Tidemasters are Atlanteans that have spent much of their wizarding experience studying the waves and how to best harness the water and produce spells that mimic the effects of many deep sea organisms.

**Best of Both Worlds.** Tidemasters are highly respected within Atlantean communities, as they have struck a careful balance between arcane academics and spirituality and wisdom as it relates to the ocean and its denizens. Typically this balance leads to a more calm demeanor paired with a highly intelligent and sharp mind which puts Tidemasters very high within Atlantean culture as they become natural advisors or councilmembers.

**Favored Beasts.** Because Tidemasters have a kindred connection with the ocean and its inhabitants, sometimes they grow particularly fond of a specific kind of ocean denizen and keep it around as a familiar; as well as have some of their signature spells match that of the beast they keep closeby.

In addition to this, consider giving a Tidemaster access to *Lobsters' Flight, Utaeli's Serrated Chomp, Angler's Charm, Utaeli's Crab Claw*, or *Jellyfish Bloom* as once a day spells to better match their personality and whatever ocean animal they have a kindred connection to.

# Atlantean Magic

Deep underneath the waves, where the light of the sun is filtered from the deep sea, Triton, Sea Elves, and other waterborne lineages gather together to protect the overworld from the deep sea monstrosities, aberrations, and elementals that seek to wreak havoc and destruction upon the material plane. After generations of fighting these creatures and protecting themselves, these deep sea protectors have developed a special kind of magic to be used deep within the waves, inspired by the deep sea creatures that they fight alongside with.

## How to Learn Atlantean Magic

Atlantean spells are inherently more powerful spells than most. Due to their innate ability of becoming empowered underwater and in the sea, Atlantean spells are made with the intention that they have the possibility of becoming more powerful than traditional spells given to characters. Because of this, Atlantean spells cannot be chosen normally and can only be taught from those who know Atlantean magic, or found via scroll or spellbook. Although it is possible for a divine or primordial entity to bless a spellcaster with the knowledge of one such Atlantean spell, the traditional way to learn these Atlantean spells would be through an Atlantean NPC or scroll/spellbook.

If a character wants to learn a Atlantean spell from an NPC, the character must take the downtime activity ‘Training’ as mentioned in Xanathar’s Guide to Everything Downtime Revisited, spending 50gp per week as opposed to 25. The character must have a friendly contact or favor with someone who knows a Atlantean spell of at least 3rd level. At the end of the Training, the character may then add one Atlantean spell that the contact knows to their list of Spells Known, provided it is of spell level that the character can cast.

Furthermore, if a character wishes to learn a Atlantean spell of 5th level or higher, the time spent in training is doubled, and the price per keep in costs of arcane supplies is 200gp per week.

\columnbreak

## Prepared vs Known Casters
   When it comes to Atlantean spells, if a character learns an Atlantean spell it is either added to their spellbook as normal if they are a wizard, it is added to their number of spells known if they are a Bard, Sorcerer, Ranger, or Warlock, and if they are a Artificer, Druid, or Cleric; it is added to their spell list and is automatically prepared without counting against the number of prepared spells that the caster can prepare.

## Submerged in Seawater

As you begin to read through these Atlantean Magic spells, you may notice that many of which contain an addendum that states, ‘When submerged in seawater.’ Since Atlantean spells were created to be used in oceanic environments, they are heightened when casted underwater, and as such, gain additional effects when the caster is fully submerged in Seawater, or when thet target of the spell is fully submerged in Seawater. If the effect of the spell has a duration that is longer than instantaneous, if the caster is no longer submerged in seawater during the duration of the spell, any amplified effects end as they are no longer being bolstered by the sea.

You create a shower of magical bioluminescence in a 10 foot cube within range. This bioluminescence gives off 30 feet of dim light. Alternatively, you can coat an object no larger than 5 feet on one side that is neither worn nor carried, or a willing medium or smaller creature with bioluminescence; where they give off 30 feet of dim light. This light is usually a light cyan blue, but you can determine the color of the light.

If you cast this spell while submerged in seawater, the duration increases to 1 hour.
