Fargo's Mod/Mothron Egg

The Mothron Egg is a item used to summon a Mothron. It can be bought from after one has already been defeated, all three Mechanical Bosses have been defeated and the world is in Hardmode.

The Mothron Egg will only work if used during a Solar Eclipse. If used when a Solar Eclipse is not currently active, the Mothron will not spawn and the item will not be consumed.
