Suspicious Looking Eye

The Suspicious Looking Eye is a consumable item that summons the Eye of Cthulhu. It is likely the first summoning item the player will obtain, and requires a Demon Altar or a Crimson Altar to craft. In addition to being crafted, they can also be found in chests in the Cavern.

The Suspicious Looking Eye will only work at night. If you try to use it in the day, it will failed and the item will not be consumed as well. If used when an Eye of Cthulhu is already spawned, it won't do anything and the item will not be consumed as well. Despite this, it is impossible to legitimately fight two Eyes at the same time, but if the message "You feel an evil presence watching you..." appears, an Eye of Cthulhu will be summoned, but this will not cancel out the Eye that was already set to appear, resulting in a second Eye joining the fight soon after the first one does.
