Mechanical Skull

The Mechanical Skull is used to summon Skeletron Prime, a harder version of Skeletron. It can only be used during night time. Using another Mechanical Skull while Skeletron Prime is already spawned will result in instant death. It can also be used in a world without hardmode activated.

If you have not defeated Skeletron Prime yet and are already in hardmode all enemies have 0.1% chance of dropping this item.
