Eberron The Chronicle Of The Last Prophecy
This byeshk spike can change size and shape into several bladed forms. It is deadly against aberrant creatures.
Weapon Enhancement: +2 to attack rolls and damage rolls Critical: +2d6 damage, +2d1 0 damage against aberrant creatures.
Property: You gain a +1 item bonus to all defenses against the
attacks of aberrant creatures.
Power (At-Will): Minor Action. Ashurta’s blade takes the shape of a broadsword (Adventurer’s Vault, page 9), dagger, longsword, shuriken, or short sword. It takes on the statistics normal for that weapon until it changes shape into another weapon.
Power (Daily): Free Action. Trigger. You hit with an attack using the weapon. Effect: A target of the attack is dazed until the end of your next turn. An aberrant creature is also restrained and cannot teleport until the end of your next turn.
The Blade was given to the Heroes after they defeated Ashurta in a trial of combat. They gave the Goblin Hero and his Guardians the rest they so well deserved.
