Ocram's Razor

Ocram's Razor is a secret boss summon item that can only be obtained in the secret Everything seed. It summons Mechdusa upon use, an amalgamation of the 3 mech bosses that drops the Waffle's iron when killed. it is crafted using 1 Mechanical skull, 1 Mechanical eye, and 1 Mechanical worm at a Mythril/Orichalcum anvil in the Everything" seed. You cannot craft it outside of the Everything'' seed and using it outside of the seed will do nothing. After use inside of the "Everything" seed, it will summon a secret boss named "Mechdusa". This boss is just a combination of the 3 mechanical bosses.

Trivia

 * This item's name is based upon Ocram, a boss that had a similarly crafted summon item before being removed from Terraria on most ports of the game.
 * Rather than directly saying what the item summons, the description states "Summons ???". This is meant to fool players into believing that this item will summon Ocram.
