The Blue Moon is a pre-Hardmode flail that, when used, will emit light around it. The Blue Moon is stronger than the Ball O' Hurt or The Meatball but is weaker than the Sunfury. The Blue Moon has a 1/7 (14.29%) chance of being obtained from the Locked Gold Chests found in the Dungeon, as well as a 1/7 (14.29%) chance of being obtained from Golden Lock Boxes(Desktop, Console and Mobile versions).

Its best modifier is Godly or Demonic. Both modifiers increase the average damage output by the same amount.


  • In Celebrationmk10(Desktop, Console and Mobile versions) worlds, the Blue Moon can be found with the normally-incompatible Legendary modifier. The size boost will not take effect, though it is still the best modifier possible.


  • The Blue Moon is especially effective in dealing with goblins, clumps of enemies, and large enemies.


  • It appears to match the Water Bolt spell and the Muramasa in appearance, likely because all these weapons are acquired from the Dungeon.
  • The item's name refers to a blue moon, a natural phenomenon.
