The Polymorph Gun is a Hardmode magic gun that can be purchased from the Adventurer. It turns enemies into Bunnies, including Bosses and Worm-type enemies. Unfortunately, it also eliminates all the Bosses and Enemies drops, instead giving Bunny drops, which means it can still be used to get Banners for the Bunny. This "Weapon" can easily speed up the Golem fight, making quick work of the head. This can also speed up ANY fight in which a boss has multiple parts, excluding moon lord.
