You know the Druidcraft cantrip.

Starting at 3rd level, you can cast the Faerie Fire spell with this trait. S

tarting at 5th level, you can also cast the Enlarge/Reduce spell with this trait.

Once you cast Faerie Fire or Enlarge/Reduce with this trait, you can't cast that spell with it again until you finish a long rest. You can also cast either of those spells using any spell slots you have of the appropriate level.

Intelligence, Wisdom, or Charisma is your spellcasting ability for these spells when you cast them with this trait (choose when you select this race).

Your fanged bite is a natural weapon, which counts as a simple melee weapon with which you are proficient. You add your Constitution modifier, instead of your Strength modifier, to the attack and damage rolls when you attack with this bite. It deals 1d4 piercing damage on a hit. While you are missing half or more of your hit points, you have advantage on attack rolls you make with this bite.

• When you attack with this bite and hit a creature that isn’t a Construct or an Undead, you can empower yourself in one of the following ways of your choice:
  • You regain hit points equal to the piercing damage dealt by the bite.
  • You gain a bonus to the next ability check or attack roll you make; the bonus equals the piercing damage dealt by the bite.
• You can empower yourself with this bite a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

Distribute 3 points among ability scores, but don't increase any ability score by more than 2.

wings or crawling

part of your body, you are forced to be attuned to your teeth always. Effects that allow you to attune to multiple items or other items regardless are unaffected. ANY spells or abilities you gain from Fairy magic or Vampiric bite must be cast using this focus, and their range are 10 feet instead of 30 feet.

In addition, any spells, abilities, or actions you perform that use your teeth to bite a creature use an attunement charge on your teeth. As you do this, they begin to feel numb or painful.

You have as many charges as your proficiency bonus which recharge after a long rest or whenever you see the moon first in a 24-hour period.
