Rise of the Twilight Empire
You gain a +1 bonus to attack and damage rolls while you are attuned to this longsword. In addition, when you hit you may spend one of your hit dice to roll that die as an extra die of damage.
This longsword was wielded by Ezroun, the shadar-kai leader of the Bonebreakers. It was found in the ruins of Raven Roost. When held, the sword grants a feeling of cold fury to the wielder.
