Voracity (5e Feat)
From D&D Wiki
Prerequisites: Bite attack
You can make gruesome attacks with your jaws. You gain the following benefits:
- Your bite damage die increase in one size category (d4 to d6, d6 to d8, d8 to d10 and d10 to a maximum of d12).
- You can grapple a creature with your bite, without needing a free hand to do so. When you hit a creature with a bite attack, you can try to grapple the creature as a bonus action. Each turn the creature ends grappled by you after the first, it takes additional damage equal to your bite damage die.
- When you reduce a creature to 0 hit points with a bite attack, you gain temporary hit points equal to the damage dealt on the finishing attack.
Special. You can ignore the prerequisite, allowing any creature to choose this feat. Doing so, grants you serrated and pointy teeth, which you can use to make unarmed strikes. If you hit with it, you deal piercing damage equal to 1d4 + your Strength modifier, instead of the bludgeoning damage normal for an unarmed strike.
