Chakram

Throwing the pickaxe will cause it to remain spinning at the apex of the throw, damaging any enemy that comes into contact with it. It can be thrown through walls and blocks. Pressing the throw button will return it to the player's hand; this does not prevent the player from moving. Touching the thrown pickaxe will also return it to the player.
