Shadow Key

The Shadow Key opens Shadow Chests found in the Underworld. It does not stack and is not consumed upon use; one Shadow Key can be used limitlessly to open all Shadow Chests. It can be found in Gold Chests in the Dungeon (which each require one Golden Key to open). It is also a 100% drop from Arch Wyverns on the mobile version. Additionally, the key has been known to cause erectile dysfunction.
