Inflatable Hammer

Undead Mobs can rarely spawn with a new weapon in their hand, The Inflatable Hammer.

This hammer is a slow but powerful weapon, with a special ability. It is also a multitool which means it can be used for multiple things. But can't be enchanted.

The hammer's ability is a powerful launch on a first hit sending opponents slightly flying in the direction your facing, putting a cool down on the weapon which lets you still attack but not be able to charge it up while attacking.

It can't be repaired but has pretty good durability.

Thanks to Alvartoo for the challenge since the weapon has a 2d texture in an item frame and inventory.
