Ice Stars are Hardmode rogue weapons sold by the Archmage NPC. They are large throwing stars made of ice, which pierce 3 times and will fall after traveling a short distance. They are stackable and cannot be recovered after impacting the ground. Ice Stars also have slight homing abilities.

Performing a stealth strike with Ice Stars will cause the next star thrown to pierce infinitely for four seconds before disappearing, and release rings of 8 smaller ice stars on enemy hits. The smaller ice stars will not be released if 10 or more stars are already present.

The Ice Star cannot be reforged, and therefore cannot have modifiers.


Used in


  • The homing ability of the weapon is extremely unreliable, as they will usually cause the projectile to fall quicker and not hit the enemy at all.
  • The stars deal one-sixth of the weapon's base damage, sharply home-in onto enemies, go through tiles, deal typeless damage, and cannot deal critical hits.


  • They can be used as an effective weapon against The Destroyer and the Aquatic Scourge as the slight homing can make them curve along the bosses' segments.
