Poison Weapon

Poison Weapon is a runic spell that appears in Ultima Underworld II.

Description
This spell poisons whatever weapon it is cast upon, allowing the mage who wields it to weaken their foes with slow-acting venom. The effect is quite similar to the Poison Daggers of Britannia, but only temporarily.

Trivia

 * A perpetually envenomed Sword of Poison Weapon may be found in Ultima Underworld II. Unlike the spell, it has no time limit.
