Essence Drain

As part of the action used to cast this spell, you must make a melee attack with a weapon against one creature within the spell’s range, otherwise the spell fails. On a hit, the target suffers the attack’s normal effects, and it becomes sheathed in crimson energy as you leech some of the lost life essence for yourself, healing for as much weapon damage as you dealt.

This spell’s damage increases when you reach higher levels. At 5th level, the melee attack deals an extra 1d6 necrotic damage to the target and you heal an additional amount equal to the necrotic damage dealt. Damage rolls increase by 1d6 at 11th level and 17th level.
