Vile Voracity

You briefly transform your mouth into a large maw or mandibles dripping with caustic ichor. Make a melee spell attack against a creature within 5 feet of you. On a hit, you deal 2d10 piercing damage + 1d10 acid damage, and regain hit points equal to your spellcasting ability modifier. If you reduce a creature that is at least one size smaller than you (Tiny at the smallest) to 0 hit points with this spell, you can choose to consume it, gaining 1d10 temporary hit points if you do so.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the acid damage increases by 1d10 and you regain additional hit points equal to your spellcasting ability modifier, for each slot level above 2nd.
