The core of this evil weapon is dotted with tiny holes that secrete a magical poison like the venom gland of a serpent. When you first discover this weapon, roll randomly on each column of the poison quality table to determine the nature of the weapon's poison. (The poison is always administered by injection.) Whenever you attack with this weapon, you may activate its hilt or handle as a bonus action to fill the weapon's core with poison; a successful attack that deals damage administers the full dose by injection. Failure to hit means the dose is wasted.
