Ornate Shadow Key

The Ornate Shadow Key is a pet item that summons a pet Shadow Mimic to follow the player around. It can be obtained from Shadow Chests, Hellstone Crates, and Obsidian Crates.

It will occasionally appear to spit out coins, but these are not collectible.

Trivia

 * The Shadow Mimic is slightly smaller than Shadow Chests or Mimics.
