You gain a +1 bonus to attack rolls and damage rolls made with this magic weapon. When you hit with an attack roll using this weapon, the target takes an extra 2d4 Necrotic damage, and it can’t regain Hit Points until the end of its next turn. If a creature is reduced to 0 Hit Points by an attack using this weapon, the creature immediately dies and can be restored to life only by a Resurrection or True Resurrection spell.
