- Internal Item ID: 329
The Shadow Key is an item used solely to open Shadow Chests found scattered in the Underworld and Obsidian Lock Boxes found from Obsidian and Hellstone Crates. It does not stack and is not consumed upon use; one Shadow Key can be used to open unlimited Shadow Chests. It can be found in Special Chests within the Dungeon (Golden Chests, Water Chests or Biome Chests), or from Golden Lock Boxes found in Dungeon and Stockade Crates. On the version, it has a 75% chance to drop from Arch Wyverns.
- In the Desktop version, Console version, and Mobile version, the Shadow Key can be found in chests alongside another unique Dungeon treasure. In the Old-gen console version, version, Switch version, and tModLoader version however, the Shadow Key will be the only unique treasure for that chest.
