Fargo's Mod/Lee's Headband

Lee's Headband is a item used to summon a Bone Lee. It can be bought from after one has already been defeated, Plantera has been defeated and the world is in Hardmode.

Lee's Headband will only work at night or if the player is underground (at or below the cavern layer). If used during the daytime or above the cavern layer, the Bone Lee will not spawn and the item will not be consumed.
