Gem
- Gem Ancestry. You trace your ancestry to a Gem dragon, granting you a special magical affinity. Choose one type of dragon from the Gem Ancestry table. This determines the damage type for your other traits as shown in the table.
| Dragon | Damage Type |
|---|---|
| Amethyst | Force |
| Crystal | Radiant |
| Emerald | Psychic |
| Sapphire | Thunder |
| Topaz | Necrotic |
- Breath Weapon. When you take the Attack action on your turn, you can replace one of your attacks with an exhalation of magical energy in a 15-foot cone. Each creature in that area must make a Dexterity saving throw (DC = 8 + your Constitution modifier + your proficiency bonus). On a failed save, the creature takes 1d10 damage of the type associated with your Gem Ancestry. On a successful save, it takes half as much damage. This damage increases by 1d10 when you reach 5th level (2d10), 11th level (3d10), and 17th level (4d10).
- You can use your Breath Weapon a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
- Draconic Resistance. You have resistance to the damage type associated with your Gem Ancestry.
- Psionic Mind. You can telepathically speak to any creature you can see within 30 feet of you. You don’t need to share a language with the creature, but the creature must be able to understand at least one language.
- Gem Flight. Starting at 5th level, you can use a bonus action to manifest spectral wings on your body. These wings last for 1 minute. For the duration, you gain a flying speed equal to your walking speed and can hover. Once you use this trait, you can’t do so again until you finish a long rest.
