History
Karn's preferred weapon of choice was his staff.
He used his staff to transfer that life force of totems. It emitted a unique energy that was strong enough to burn the Wolverine of Earth-8351[1] and could be used as a projectile.[2]
The staff was the key to the Master Weaver's, Karn's future-self, orb. After realizing this, Karn discarded his staff.[3]
