Geomancer

Gemstone Specialty

Starting at 1st level, you gain two specialty gems of your choice, with abilities listed at the end of the class. You begin with one of each. You may use an action to place or remove a single gemstone into either a piece of armor. Only your specialty gemstones can be placed into armor or weapons, and only your specialty gemstones give you the benefits detailed at the end of the class description. Also, as you level up, you gain more specialty gemstones and gain their benefits when using them. You may swap out old specialty gemstones with new ones at 3rd, 6th, 9th, 11th, and 16th level, but your old specialty gemstones then lose their magic and you can no longer use them. These gemstones are worthless to anyone but you. For any saves the gemstones have the target make, you use the following save DC.

Gemstone Save DC = 8 + your proficiency bonus +

your Wisdom modifier

Additionally, you have advantage on Wisdom (Insight) checks to determine the value and type of regular gemstones.

Crystalline Armory

Since adding gemstones to your armor is difficult, you have either made your own armor or have had it specially made by another to accommodate and harness the power of gemstones. Starting at 1st level, your armor and weapons have been specially designed to hold and use the power of gemstones. You have 3 gem slots + 1 extra slot available to you while you wield a weapon. Only you are proficient with this equipment, and only you gain the benefits from it.

The power of your gemstones runs through all of your equipment you have designed, no matter what weapon or piece of armor it is placed in. Since this is your armor, this is your design, so be creative. If you want a piece of equipment to be shaped for this, you must spend 24 hours, using fire to do this. You may use this ability on magic items as well. This requires nothing but jeweler's tools to do.

Gem Extraction

You have connected yourself to the gemstones in the plane of earth, and therefore can extract them from the endless bounds of gems that the plane holds. However, searching for the gemstones with the correct level of power is difficult. Beginning at 2nd level, once per long rest, you may extract one gemstone from the plane of earth. However, this gemstone must be one of your specialty gemstones. These gemstones are worthless to anyone but you.

Fighting Style

At 2nd level, you adopt a particular style of fighting as your specialty. Choose one of the following options. You can’t take a Fighting Style option more than once, even if you later get to choose again.

Archery

You gain a +2 bonus to attack rolls you make with ranged weapons.

Shield Fighting

When you use a shield, you instead gain a +2 bonus to your AC. Alternatively, you can use your action to attack with your shield, which deals 1d8 + your strength modifier bludgeoning damage making your AC bonus +1 while you are attacking with it. You must use another action to use your shield normally.

Dueling

When you are wielding a melee weapon in one hand and no other weapons, you gain a +2 bonus to damage rolls with that weapon.

Earthen Bound

Using gems has taught you much about shaping the earth. This has made it so you can now scoop through the earth as if it were warm cheese. You gain a burrowing speed of 30 feet. In addition, you gain 30 feet of darkvision. if you already have darkvision, add 30 feet to your darkvision, as with burrowing speed.

At 15th level, both of these abilities become 60 feet.

Gemstone's Endurance

At 11th level, you become as tough as the hardest diamond. Once per long rest, you may recollect your energy and recover three points of exhaustion. This can be divided into seperate uses or used all at once.

Gemstone's Age

Beginning at 14th level, you begin to age like a stone. For every 20 years that pass, you age only one year. In addition, you cannot be aged magically, and no longer require food or water.

Gemstone Domain

Your constant work with gems allows you to understand the workings of the earth better, and you are only strengthened when you are surrounded by it. Starting at 15th level, as long as you're covered by at least 10 feet of ground, you gain the following benefits:

• All of your speeds are increased by 15 feet
• Your AC is increased by 2
• You have resistance to nonmagical bludgeoning, piercing, and slashing attacks
• All your attacks deal 2d6 more damage
• You have blindsight and truesight for 10 feet
• Your burrowing speed is increased by an additional 20 feet, and you can burrow through solid rock at half your burrowing speed and can leave a 5-foot-diameter tunnel in your wake
• As long as you can see, you have advantage on all attacks and Wisdom saving throws

Crystal Mines

At 17th level, your study of gemstones has taught you the instability of the power they possess, or at least the potential of it. During a short or long rest, you may take a gem from the plane of earth and fix it as a sort of bomb. You may only have two of these gems at once. If you make another of these, you must choose one gem to return to a stable state. There are three types of these bombs. Choose one to make during a short or long rest.

The save DC for these attacks is 8 + your proficiency bonus + your wisdom modifier.

Shrapnel Blast

Bomb Blast

This gem, upon explosion, acts as a regular bomb, forcing the creature to make a dexterity saving throw upon throwing this gem. On a failed save, they take 4d12 bludgeoning damage, along with becoming stunned, and half as much on a successful one but not becoming stunned. Creatures within 5 feet of this creature must also make a dexterity saving throw or take 3d8 force damage.

Prerequisite: 11th level

Little eyes seem to litter all over this gem, and if you look closely, they seem to almost be moving. With this gem, as an action, you may gain the ability to see through solid objects to a range of 40 feet. During this time, you perceive objects as ghostly, transparent images.

Also, you can use an action to touch a willing creature and see through their eyes. As long as the creature is on the same plane of existence as you, you can use your action on subsequent turns to maintain this connection, extending the duration until the end of your next turn.

You cannot use these abilities simultaneously.

Shapechange Gem

Prerequisite: 11th level

Holding this gem, you hear faint and annoying shouting, and listening for too long drives you slightly crazy. With this gem, as an action, you may transform your appearance or revert to your natural form. You decide what you look like, including your height, weight, facial features, the sound of your voice, coloration, hair length, sex, and any other distinguishing characteristics.

You can’t duplicate the appearance of a creature you’ve never seen, and you revert to your natural form if you die. You can make yourself appear as a member of another race, though none of your game statistics change. You also can’t appear as a creature of a different size than you, and your basic shape stays the same; if you’re bipedal, you can’t use this trait to become quadrupedal, for instance. Your clothing and other equipment don’t change in appearance, size, or shape to match your new form.

You may create up to 5 mirages at one time, and each mirage lasts for 1 minute.

Wild Gem

Prerequisite: 16th level

With this gem, twice per long rest, you may use this gem to create a surge of wild magic. Roll from the Wild Surge Table to find out what happens.

Gem Crafts

All geomancers must choose a craft to further their expertise in gems. A craft is the specific art of a geomancer that separates them from other geomancers. The geomancers of the Monster Aspect Craft use foreign and forgotten stones to better understand monsters. Those of the Black Stone Craft see the potential for spells in gemstones and seek to use them.

Learning the Monster

You are beginning to learn the ways of your selected monster type. Beginning at 3rd level, you gain one of the following abilities:

The Fey

Death burn of the Darkling Elder: When you die or drop unconscious and begin dying, magical light flashes out from you in a 10-foot radius as your and possessions, other than metal or magic objects, burn to ash. Any creature in that area must make a Constitution saving throw. On a failure, the creature takes 6d6 radiant damage and, if the creature can see the light, is blinded until the end of its next turn. If the saving throw is successful, the creature takes half the damage and isn't blinded.

At 13th level, this damage becomes 6d8, and at 18th, it becomes 6d10. Anything that burns reappears in 1d4 minutes.

The Celestial

Divinity of the Planetar: You gain the following abilities:

Divine Awareness. You know if you hear a lie.

Monster Attunement

At 13th level, you gain a benefit based on your selected monster type.

One With Monsters

You have mastered your selected study and now have gained one final benefit from all your studying at 18th level.

The Slaadi

Slaad are violent toad-like monsters residing in the plane of Limbo. They are cruel and monstrous beings that have many stages of life that they go through and reproduce by infecting others with a disease called chaos phage, or putting eggs in their brain. While putting eggs into a creature's body will inevitably end in their death, a small fraction of geomancers have learned about how to control the chaos phage disease.

Slaads are controlled by a gem, and extracting the gemstone allows the user to control the slaad. While this is mostly used by mad wizards or evil sorcerers, a few geomancers learned how to use these gemstones too. These geomancers purposefully infect themselves with the chaos phage and wait for their transformation to be completed. Once transformed, they quickly touch a shard of The Spawning Stone before they lose control of themselves, creating a gemstone inside their brains, and then skillfully extract it, placing it in the center of their chests. Because geomancers are masters of gemstones, they then, through intense and backbreaking training, allow their stone to absorb their slaadi body and deposition. However, when they choose to embrace their slaadi body, they must be careful to not stay in the form for too long, as being in the form too long will result in permanent loss of control.

When new geomancers enter this craft, the elders of the craft infect the apprentices when they are ready and help them control this new power. However, they wait patiently for this, as they only infect those who are willing to fully follow this craft. Despite this, these geomancers are looked down upon others, as many believe that this craft uses dark magic and ruthlessness to obtain their power.

Just as normal slaad, as these geomancers grow in power and control of the disease, they change forms, such as blue to green, and their gem changes with them. Eventually, when they become masters of their power, they become death slaads, the most powerful of the slaads. They have learned that obtaining enough power instead of killing a death slaad is enough to make them a death slaad, and because they have trained for this, their alignment stays the same.

Slaadi Gemstone

At 3rd level, you have your slaadic gemstone in the middle of your chest. This gemstone gives off bright light for 10 feet and dim light for 10 feet, regardless of if you are wearing armor or not.

You cannot be disarmed of this gemstone, but the same spells that are used to extract a normal slaad's gemstone can be used to extract yours. However, when someone takes your gemstone, you are not under their control.

Slaad Transformation

Once this craft is chosen at 3rd level, you begin to learn how to control this disease still running through you. As a bonus action, you may take on your slaadic self for 1 hour. You can speak, use equipment, and wear armor in this form. You can also revert to your normal form earlier as a bonus action. You automatically revert to your normal form if you fall unconscious, drop to 0 hit points, or die.

Once this feature has been used, it cannot be used again until you finish a short or long rest.

Slaad Transformation Features

While transformed, you gain the following features:

Slaad Color. You begin as a red or blue slaad, and your slaad color as of now is red/blue. This color does not affect your abilities during your transformation.

Inpenetrable Skin. You gain resistance to acid, cold, fire, lightning, and thunder damage.

Sharp Claws. You can use Dexterity instead of Strength for the attack and damage rolls of your unarmed strikes. When you use the Attack action with an unarmed strike, you can make one unarmed strike as a bonus action. Your unarmed strikes deal 1d6 slashing damage. The damage increases to 1d8 at 13th level.

Chaos Phage. You haven't yet learned how to completely control the chaos phage disease, causing you to sometimes lose control, especially when it's difficult to concentrate. If you begin your turn with no more than half of your maximum hit points, you must succeed on a DC 8 Wisdom saving throw or move directly towards the nearest creature to you and use the Attack action against that creature. You can choose whether or not to use your Extra Attack feature for this frenzied attack. If there is more than one possible target, roll to randomly determine the target. You then regain control for the remainder of your turn.

If you are under an effect that prevents you from concentrating (like the barbarian’s Rage feature), you automatically fail this saving throw.

Slaad Transformation

At 7th level, your slaad form has changed and become more powerful. You are now a green slaad, and you now have more abilities.

Infectious. You have learned how to plant eggs in others without passing the disease on. Once per long rest, you may plant a tiny egg inside the body of the target. While the egg resides in the creature, the target gains disadvantage on attack rolls, and their speed is halved. This egg remains in the creature's body for 24 hours, where it then disintegrates.

At 18th level, you may do this twice per long rest.

Sharper Claws. Also at 7th level, when using your unarmed strikes in slaad form, you may use your specialty gemstone abilities on your unarmed strikes. While using them on your unarmed strikes, your attacks count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.

In addition, you gain +1 to melee damage rolls while in your slaad form and have an advantage on Strength checks and saving throws.

Advanced Slaad Transformation

At 13th level, it is time to shed your green slaad skin, and you are now a gray slaad. You have taken more control of your slaad form as well, granting you the ability to transform into your slaad form twice per long rest. In addition, you gain the Slaadi Regeneration feature.

Slaadi Regeneration. At the start of each of your turns, before you roll for the chaos phage trait, you regain hit points equal to 1 + your Constitution modifier (minimum of 1) if you have at least 1 hit point and have less than half of your hit points remaining.

Slaad Mastery

At 18th level, you have transformed into the king of all slaads, the death slaad. In addition, you have dominated and controlled your slaad form, and as such may transform into your slaad form an infinite amount of times, and can stay in this form indefinitely.

You also gain advantage on saving throws against spells and other magical attacks.

Gem Warrior

Some Geomancers look for other gems as sources of power. Some look to evil beings. However, those of the Gem Warrior craft seek to take the raw power of gemstones to the next level. They seek to add even more gemstones to their armor, using any place they can find on the armor as a spot to place another. However, too much power can destroy even the strongest of fighters, so Gem Warriors have the tedious task of channeling and controlling that power to keep it in check. However, those who successfully achieve this are able to wield the true light and energy of gemstones.

Warrior’s Protection

Beginning at 7th level, you gain yet another gem slot, this one being on your helm. If you don't have a helmet, place this gem slot in a place of your choosing. Also, you may morph your armor to cover your entire face as a bonus action. However, your vision and hearing are compromised a bit, giving you disadvantage on Wisdom (Perception) checks. You gain a +4 to your armor class. In addition, you gain advantage on Charisma (Intimidation) checks during this time.

You may end this effect as a bonus action at any time.

Extra Slots

Starting at 13th level, you are continuing to harness the power of extra gem slots. You gain one additional gem slot and one additional specialty gemstone. Also, you begin to radiate light because of your extra gemstones. You give off bright light for 5 feet and give off dim light for 5 feet, and you can turn this effect off at any time. Also, your armory begins to improve because of the pure light and power you yield. As a bonus action, you may have two daggers sprout from your armor. These daggers have the same properties as +3 daggers, but these daggers deal radiant damage. Also, when you throw these daggers, they give off blasts of energy, and each creature within 10 feet of them when they are thrown takes 3d10 radiant damage and must make a Constitution saving throw or be blasted 10 feet away. If you drop or throw these daggers, you may summon them back to your hands as a bonus action.

At 18th level, you may use these daggers indefinitely, and the damage die of the blast becomes 6d10.

Warrior’s Weapon

Beginning at 18th level, you have learned to perfectly control the power of gemstones. You gain another extra gem slot, this one on one weapon. Weapons you use are now bonded to you and cannot be disarmed from you. Your mastery over gemstones now allows you to harness their pure light and power to make your weapon attacks radiant damage instead of bludgeoning, piercing, and slashing damage. In addition, your weapons give off bright light for an additional 20 feet and dim light for an additional 10 feet unless you choose not to have them do so and you gain +5 to all attack and damage rolls made with this weapon.

Black Order

The Black Order Craft was not always such a dark and inhumane craft. In the beginning, the thought that geomancers could cast spells through the power of gemstones seemed simple enough, and many grew to support this ideal. However, what started out as a simple craft of geomancers became a much different force when Vox Ruthynil joined this craft. As a boy, Vox had learned from an early age the idea of taking resources from innocent creatures for further gain, which would culminate to him killing an adult owlbear at age 10 and using its feathers as a cloak. His parents, seeing this as a bad path to take, realized that they needed to stop this and sent their son to live with his uncle, whom was a geomancer of the Black Order craft, then known as the Crystalline Magic craft and a symbol of prosperity. This temporarily subdued the path of Vox and allowed him to grow into a fine young man a member of the craft, which by this time, his uncle was the leader of. However, a near death experience with a pack of snowy wolves would cause Vox to lash out in a fit of power. The color drained from his face and gemstones, normal spellcasting effects, but then he began drawing the misty, silky souls of these wolves into his stones. Realizing this newfound power, Vox saw no need for his uncle, now the leader of his craft, nor any need for the craft as a whole. While many tried to stop him, Vox began to eliminate any traces or members of the craft, all while gaining followers he taught himself, creating the Black Order. This dark craft relies on necromancy and evocation spells.

Spellcasting Focus

You may use the Blackened Jet Gemstone that you receive when joining the craft as your spellcasting focus.

Spellcasting Ability

Wisdom is your spellcasting ability for your wizard spells, since you learn your spells through study and memorization. You use your Wisdom whenever a spell refers to your spellcasting ability. In addition, you use your Wisdom modifier when setting the saving throw DC for a wizard spell you cast and when making an attack roll with one.

Spell Save DC = 8 + your proficiency bonus +

your Wisdom modifier

Spell attack modifier = your proficiency bonus +

your Wisdom modifier

Strengthened Connection

At 3rd level, you recieve the Blackened Jet gemstone, which you can place in your armor without taking up a gem slot, and you have connected yourself further to the plane of earth to allow you to cast spells. You now only need a short rest to use your gem extraction feature.

In addition, if the material components of a spell are not consumed but have a value in gold, you may use a precious gem worth the same as or more than the material components required.

Regain Energy

At 7th level, you learn to absorb the souls of your enemies and to use them as fuel for your spells. Every time you or one of your allies slays a foe, you may choose to use your Blackened Jet gemstone as a source to hold onto this soul to serve you one last purpose. Once you gather 5 souls, you may use an action to regain one 1st level spell slot.

Once you capture a dead soul, it remains with you for 12 hours, after which it moves on to the spirit world. At 13th level, you may regain one 2nd level spell slot this way.

Magic Absorption

Starting at 13th level, you have further understand the art of holding souls of creatures within stones. Whenever you or your allies knock a creature that isn't undead or a construct below 15 hit points, you may use an action to force the creature to make a constitution saving throw, sucking their soul into one of your stones before death, therefore incapacitating them.

Alternatively, because you have now learned how to transfer the life energy found in gemstones to others, you can instead use an action to transfer 3d10 hit points from the soul of the creature to an ally within 60 feet of you.

Masterful Connection

At 18th level, you have mastered your connection to the plane of earth, allowing you to only need an action to use your gem extraction feature. You have also mastered the art of regaining spell energy from gems. You may use an action to regain one 2nd or 3rd level spell slot. However, only spells with base levels of 2nd and 3rd can be used with these slots, and they must be used at their base level.

Additionally, once per long rest, you call upon all the gemstones you've destroyed and ruined that have brought you to this point to have them serve you one last purpose. You may center a 30 foot sphere around a creature, and all creatures except for those you choose not to must roll a Dexterity saving throw. On a failed save, they become wrapped in tendrils of black stone, becoming restrained, and they take 10d10 bludgeoning damage, or half as much and not being restrained on a successful one.

Gemstone Dragon

Gemstone dragons are mysterious and reclusive creatures with few adventurers even getting a glimpse of them in their entire lifetimes. To stay away from society, these crafty creatures build extensive cave systems where they can live in peace away from humans. However, due to human greed and curiosity, the homes of these beasts began to become disgruntled and destroyed, and these dragons soon were hunted for their special psionic abilities and treasures.

Draconic Bond

At 3rd level, you have a bond formed with a dragon. Choose one type of dragon as the creator of this bond. Features you gain later use the damage type associated with each dragon.

Gemstone Companion

Whether through a ritual, encounter with a gemstone dragon that gives you their young to bond with, or through a random find, you obtain an egg that then hatches at 3rd level to give you your dragon companion.

If you are ever slain (in battle or otherwise), your dragon will also die after a number of hours equal to your dragon knight level, during which it will attempt to do everything in its power to return you to life.

If your dragon companion is ever slain, the magical bond you share allows you to return it to life. With 8 hours of work and the expenditure of 25 gp worth of precious gems per your dragon knight level, you can call forth your companion's spirit and use your magic to create a new body for it. You can return a dragon companion to life in this manner even if you do not possess any part of its body.

Returning your dragon to life is a gruelling process, and you must expend some of your own life force to compel the dragon back to life. You can choose to expend any number of hit dice when you finish the ritual. Make a Charisma check, with the DC being equal to 15 minus the number of hit dice you expended. The DC cannot be lowered below 5 in this way.

On a failed ability check, the dragon is restored to life, but you aren't able to regain any of the hit dice you expended for the ritual until 7 days have passed. Additionally, you and your dragon both suffer three points of exhaustion. On a successful ability check, the dragon is restored to life, and you can regain the spent hit dice as normal.

Gemstone Bond

Also at 3rd level, your dragon gains many benefits while you two are together.

Your dragon obeys your commands as best it can. It rolls initiative like any other creature, but you determine its actions, decisions, attitudes, and so on (no action required by you). Your dragon shares your initiative, and takes its turn immediately after yours. If you are incapacitated, your dragon acts on its own, and if you're absent, it rolls its own initiative.

Your dragon can move and use its reaction on its own, but the only action it takes on its turn is the Dodge action unless you take a bonus action on your turn to instruct it to take another action. If you are incapacitated, your dragon can take any action of its choice, not just Dodge.

Also because of its youth, it has yet to master flying, and as such, falls if it ends its turn in the air. Additionally, it can't fly with a creature it has grappled or be used as a mount until you reach 13th level, at which point it is strong enough and properly trained to support other creatures.

Your dragon companion has abilities and game statistics determined in part by your level. Your dragon uses your proficiency bonus rather than its own. While not wearing barding, a dragon companion has a natural armour class of 10 + its Constitution modifier + your proficiency bonus.

Your dragon companion is proficient in all the saving throws you're proficient in, and has two proficiencies of your choice. Also, your dragon companion can't attune to or activate magical items.

For each level after 3rd, your dragon companion gains an additional hit die and increases its hit points accordingly. The dragon's hit dice are d10s, regardless of its size. When the dragon is reduced to 0 hit points, it makes death saving throws as a player would.

Also, you and your dragon always know the direction to one another, and can communicate with vague images, emotions, and feelings, regardless of distance.

In addition, the dragon cannot have its size increased beyond large (but would still gain the extra benefits of the enlarge/reduce spell, for example). The dragon's level is equal to your geomancer level for the purpose of calculating spells like polymorph and true polymorph.

Whenever you gain the Ability Score Improvement class feature, your dragon's abilities also improve. Your dragon can increase one ability score of your choice by 2, or it can increase two ability scores of your choice by 1. As normal, your dragon can't increase an ability score above 20 using this feature.

Wyrmling Advancement

Starting at 7th level, your dragon companion continues to grow, and gains the following benefits:

• Its claw attacks deal an additional 1d4 slashing damage.
• Its flying speed increases by 15 feet, and its other speeds increase by 5 feet
• The dragon's wings are stronger, and it no longer falls to the ground if it ends its turn in the air
• The dragon may act as another gem slot for you, and as such can use its action to activate a gemstone that it's holding's abilities
• Its claw attacks count as magical for the purposes of overcoming resistances and immunity to nonmagical attacks and damage

Breath Weapon

Also at 7th level, your dragon has developed the glands to shoot raw, destructive elements from its mouth, with the saving throw calculated as follows:

Breath Save DC = 8 + your proficiency bonus +

your dragon's Constitution modifier

The shape of the breath is different depending on the colour of your dragon, as shown in the table below. The damage is the same as the dragon's relevant damage type (e.g. a red dragon's breath would deal fire damage).

Dragon	Breath Weapon
Amethyst	15 ft. cone (Strength save)
Crystal	15 ft. cone (Con. save)
Emerald	15 ft. cone (Int. save)
Sapphire	15 ft. cone (Con. save)
Topaz	15 ft. cone (Con. save)

   

As an action on its turn, the dragon can breathe its relevant destructive energy in a cone as shown on the table. Each creature in the area takes 4d6 damage on a failed save, or half as much on a successful one.

The area of the line and cone and the damage of the breath weapon increase as you gain levels in this class, as shown below.

Your dragon can use this ability twice, and it regains all expended uses when you finish a short or long rest.

Level	Damage	Area
7th	4d6	15 ft. cone
13th	7d6	30 ft. cone
18th	9d6	60 ft. cone

Young Advancement

At 13th level, your dragon companion still grows, and gains the additional following benefits:

• The dragon's size is now large
• Its flying speed increases by 15 feet, and its other speeds increase by 5 feet
• As long as your dragon can see you, it has advantage on all saving throws
• Its claw attacks deal an additional 1d4 slashing damage

Gemstone Lair

Also at 13th level, you and your dragon begin to use the gemstones you possess as conduits for your dragon's lair. You and your dragon gain abilities respective to the dragon type. The DC for the following saving throws is 16.

Amethyst. Twice per short or long rest, you or your dragon can choose an open space with 5 additional feet of open space surrounding it. You exist in your own space and the chosen space simultaneously until the end of your next turn. During this time, whenever you move or take an action, you may choose which version of yourself or your dragon is moving or acting. If an effect that can target both versions is used, you are only effected once.

Crystal. You or your dragon can choose a point that you can see within 60 feet. As an action, you or your dragon may force all creatures in the area to succeed on a Dexterity saving throw or take 2d12 radiant damage and be outlined in light. While a creature is outlined in light, all attacks made against them have advantage. The light fades at the end of your next turn.

Emerald. You or your dragon may use an action to cause yourself to become invisible, and you gain the invisible condition until until the end of your next turn.

Sapphire. You or your dragon may as an action choose one creature. That creature is enveloped in thunderous sound that can be heard up to 100 feet away, and that creature must succeed on a Constitution saving throw or take 3d8 thunder damage and become stunned until the end of its next turn.

Topaz. You or your dragon may choose up to two creatures within 60 feet of you. As an action, you may force them to succeed on a Constitution saving throw or take 4d6 necrotic damage. In addition, negative energy surrounds the creatures, and all creatures you choose within 60 feet cannot regain hit points until the end of your next turn.

Gemstone's Power

At 18th level, you and your dragon have discovered the true power of the gemstones you possess, and have created a bond strong enough to use this power in battle. You are now immune to your dragon's damage type. Once per long rest, each dragon respectively may use an ability. Use your spell save DC for any saves you make for these abilities.

Amethyst. Your dragon spits an amethyst out of its mouth that explodes at a point it can see within 60 feet. Each creature within a 20 foot radius centered around that point must succeed on a Dexterity saving throw or take 4d8 force damage and be knocked prone.

Crystal. Your dragon releases a searing beam of starlight at a creature it can see within 60 feet. The target must succeed on a Dexterity saving throw or take 11d6 radiant damage.

Emerald. Your dragon creates a mote of dancing green flames around a creature you can see within 60 feet of you. That creature must succeed on a Dexterity saving throw or take 12d6 fire damage.

Sapphire. Your dragon telekinetically causes a giant piece of sapphire to rise from the ground, and then flings it at a creature it can see within 60 feet. That creature must succeed on a Dexterity saving throw or take 6d8 bludgeoning damage and be stunned until its next turn.

Topaz. Your dragon chooses a creature or object it can see within 60 feet. That target must make a Constitution saving throw or take 9d8 necrotic damage. If this damage sets the target to 0 hit points, it crumbles to dust.
