Celestial Sigil

The Celestial Sigil is boss-summoning item crafted out of 20 of each of the Celestial Tower's fragments. It is used to summon the Moon Lord without going through the Lunar Events. The Lunar Events must not be active (there cannot be Celestial Towers in the world) to use the item. This item cannot be used when you are able to see the Lunatic Devote and/or Blue Cultist Archer on your screen (Possible bug?). It also cannot be used in a world in which the Golem has not been defeated.

Trivia

 * It strongly resembles the Mysterious Tablet, the strange idol near the Dungeon, which helps trigger the Lunar Events.
