The Gacruxian Mollusk is a Hardmode non-consumable rogue weapon that can be fished up in the Astral Infection. When used, it throws a snail that drops sparks as it travels. The snail travels in a straight line for a moderate distance before being affected by gravity. The sparks are affected by gravity, ignore tiles, and weakly home in on enemies.

Performing a stealth strike with the Gacruxian Mollusk will cause the snail to leave a trail of additional snails, which continuously emit sparks for 3 seconds before disappearing. These additional snails will strongly home in on nearby enemies, or hover in place if no enemies are close enough.

Its best modifier is Flawless.


  • This weapon's functionality is similar to the Spear of Paleolith, another early-Hardmode rogue weapon. The Spear of Paleolith has higher base damage and inflicts Armor Crunch, while the Gacruxian Mollusk has homing and a unique stealth strike effect.
  • This weapon does not benefit from the effects of the Invisibility Potion or the Shadow Potion.


  • Its name is a reference to Gacrux, which is a red giant star in the Crux (Southern Cross) constellation.
