The Rune spear (kp) is a quest item used during Tai Bwo Wannai Trio. It is created by poisoning a rune spear with poison karambwan paste, and is given to Tamayu so that he is able to defeat The Shaikahan. The poisoned spear is not equipable and not tradeable, and has no use outside of the quest. Unlike standard poison, there is no longer any way to use karambwan poison in combat. The poison can be removed with a cleaning cloth, resulting in a tradeable rune spear.
