Deathly Touch

Deathly Touch. Melee Attack: automatic hit, reach 5 ft., one target. Hit: [[character level]/2]D10 necrotic damage. The target must succeed on a constitution saving throw DC (8+prof+ability modifier) or its hit point maximum is reduced by an amount equal to the damage taken. The target dies if its hit point maximum is reduced to 0. This reduction to the target’s hit point maximum lasts until the target finishes a long rest. When Deathly touch is used the user can self heal for up to half the damage taken by its target. Once used, Deathly touch cannot be used again until the next dawn.
