The Blue Moon attacking Target Dummies.

The Blue Moon is a flail that can be found in Gold Chests within the Dungeon, or Golden Lock Boxes found in Dungeon and Stockade Crates. When used, it will emit light around it. The Blue Moon is stronger than the Ball O' Hurt or The Meatball, but is weaker than the Sunfury.

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

Notes

In Celebrationmk10 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.
