Glacier Hammer

The Glacier Hammer is the third of the Legacy Weapons, and is imbued with the power of overwhelming cold and ice. It was once used to freeze the world, but them all the ice was sealed away into the heart of the stone in the head.
The overwhelming cold in this oversized ice mallet allows the wielder to summon ice storms, and freeze any amount of land at a time. However, it is extremely heavy for all, meaning that the wielder either needs a mechanical hand (and/or arm) or a hell of a lot of strength to lift it.
