Mechanical Worm

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

If you have not defeated The Destroyer yet and are already in hardmode, all enemies (minus statue-spawned monsters and meteor heads) have a 1 in 2500 chance of dropping this item.

Trivia

 * On the Console and Mobile versions of terraria, this is the only mechanical boss summoning item that does not have a suspicious looking variant, however the PC version lacks the Suspicious Looking Skull so on PC its not the only one.
