Qwerty's Bosses and Items/Doppleganger

The Doppleganger is an Expert Mode-exclusive accessory obtained by opening 's. Equipping it copies the properties of the accessory in the slot above. It cannot be placed in the topmost slot. It may not work with some accessories like the Shield of Cthulhu.

The Doppleganger cannot be reforged. Attempting to do so kills the Goblin Tinkerer and the player with the death message "&lt;Player name&gt; tampered with forces beyond his/her control!" In Hardcore, the player will not be killed, but they will still be unable to reforge the item, and the status message "You shouldn't tamper with things beyond your control!" appears.
