The Icebreaker is a Hardmode rogue boomerang that is dropped by Cryogen. It throws ice hammers at a long range. The projectiles return to the user after hitting a solid block right by you, or when they reach the end of their throwing range. Multiple projectiles can be thrown at the same time and can phase through tiles while returning to the player.

Performing a stealth strike with the Icebreaker causes cosmic explosions to appear on enemy hits. The explosions inflict the Nightwither and Glacial State debuffs and deal 1.5 times the damage.

Its best modifier is Flawless.
