Devour

You manifest a shadowy beast with a large maw to pounce on a target and devour them.

You may choose a target within 60 ft. of you to cast this on, dealing 3d6 necrotic damage if the fail a Constitution Save equal to your spellcasting DC. If a target is bellow their hitpoints maximum, this spell deals twice the damage it would. If this spell reduces a target to 0 hitpoints, the targets body disappears, leaving only clothing and items they had on them, in addition to the caster gaining hitpoints equal to the damage which reduced the target to 0.
