Drain Life

You drain the blood - and very life force - from a creature's wounds. A ranged spell attack is made against a wounded target within range. This creature must have lost at least one hitpoint from its maximum to be considered wounded.

When using this spell, the caster takes 1d6 necrotic damage (regardless if the spell hits). On a successful attack, the creature takes 3d6 necrotic damage, and the caster regains lost hitpoints up to their maximum from the damage dealt.
