Not to be confused with Robotic Skull, the Master Mode pet for Skeletron Prime.

The Mechanical Skull is a Hardmode boss-summoning item used to summon Skeletron Prime, the Hardmode version of Skeletron. It can only be used at night; attempting to use this item during the day will not spawn Skeletron Prime nor consume the item. The Mechanical Skull is also unusable while Skeletron Prime is already alive. If Skeletron Prime has not been defeated yet in a Hardmode world, all enemies have a 1/2500 (0.04%) chance of dropping a Mechanical Skull, with the exception of statue-spawned enemies, Meteor Heads, and Old One's Army enemies.

Notes

  • (Desktop, Console and Mobile versions) In the get fixed boi secret world seed, the Mechanical Skull is not consumable and is instead a crafting material for the Ocram's Razor, an item used to summon Mechdusa.
  • Like other mechanical boss summoning items, the Mechanical Skull can be brought to pre-Hardmode worlds and will successfully summon Skeletron Prime there.
  • As with several items, the Mechanical Skull has multiple crafting recipes (two in total) due to some items in the recipe allowing substitutes.
