The Mechanical Eye is used to summon The Twins, the advanced and Hardmode version of the Eye of Cthulhu. It can only be used at night; using this item during the day will not spawn The Twins or consume it. Using another Mechanical Eye while the The Twins are active will not cause any additional effects, and will not be consumed. If The Twins have not been defeated yet and the world is already in Hardmode, all enemies (with the exception of statue-spawned enemies) have a 0.04*1/2500 (0.04%) chance of dropping this item.

Notes[edit | edit source]

  • Like other mechanical boss-summoning items, the Mechanical Eye can be brought to pre-Hardmode worlds and will successfully summon The Twins there.
  • As with several items, the Mechanical Eye has multiple crafting recipes (two in total) due to some items in the recipe allowing substitutes.
