Cursed Hammer

The Cursed Hammer is a Hardmode enemy that spawns in the Underground Corruption. It hovers and spins before flying at the player, traveling through blocks. Any knockback stops its attack, forcing it to pause and spin up again. It can inflict the Cursed debuff.

Cursed Hammer is immune to the Poisoned, On Fire!, and Cursed Inferno debuffs.

The Shadow Hammer is a console/mobile-exclusive version with increased damage and defense.

Trivia

 * Most likely a tribute to Castlevania, where swords and hammers have the same attack pattern.
 * The Cursed Hammer is the only one of the three cursed weapon enemies to use a sprite not based on an existing weapon. (And Shadow Hammer on console and mobile)
