Blue Moon

Blue Moon is a flail that can be acquired from the Dungeon. The flail has 30 damage and slow speed.

It shoots blue spiky ball that lights area around it forward, and damages everything the ball touches. When ball goes too far or hits a block, it starts going back to the player, even through the walls.

Using flail in small range is very useful. As long as it hits any block fast, it comes straight back to the player and you can shoot it right away again. Of course, when the ball is in air, you can not change weapons or shoot it again.
