Umaril's Sword

Umaril's Sword is an enchanted claymore wielded twice by Umaril the Unfeathered during the quest of the same name, as part of the Knights of the Nine plug-in. True to the nature of Umaril and his Aurorans, the blade has the property of Shock Damage 14 pts on Strike. It also features Damage Fatigue 11 pts on strike.

You can obtain two of these blades, one from each of two stages in your fight against Umaril. The first you can find next to his bodily corpse (or as loot on his body) and the second you will probably have to catch as you and the blade fall from the heavens.
