Hammush

The Hammush is a Hardmode Hammer that can be bought from the Truffle NPC. When swung, the Hammush produces spinning mushrooms like that of the Mushroom Spear, which damage enemies even through walls. This, in addition to retaining the ability to smash Demon Altars, makes the Hammush a direct upgrade from the Pwnhammer.

Trivia
