Devour

This spell turns corpses into consumable essence which is also caused to be devoured in its casting to heal the caster. Choose up to two piles of bones or corpses within range. Your spell turns the corpses into raw essence which is then absorbed into you, healing you for 1d6 hit points for each corpse. Every corpse consumed by this spell is, in fact, consumed upon having this spell cast on them, rendering them nonexistent anymore afterwards.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you can consume up to two additional corpses for each slot level above 2nd.
