In-game description
"This finely crafted stave was among the spoils taken from the invaders of Durlag's Tower. It is very deadly in combat, and was apparently the property of a spellcaster enjoyed standing on the frontlines. It appears to have a core of iron, yet it is comparable in weight to a normal weapon of its type. Part of the enchantment seems to come from the hide that strenghtens the grip, leather no doubt made from a battle-ready creature or some sort. With the tastes and inclinations of the attackers of the Tower well documented, the hide could be almost anything...or anyone."
