Shadow Chest

The Shadow Chest is a storage item found only in the Underworld, generally on top of or within Ruined Houses, and contains rare items. All Shadow Chests are initially locked, requiring a Shadow Key to open. A single Shadow Key will open unlimited Shadow Chests (unlike Golden Keys, which are consumed upon use). Each Shadow Chest contains one high-tier item of "Orange" rarity, along with other standard Underground loot.

Like all other naturally-occurring Chests, Shadow Chests can be freed with a Pickaxe or Drill after being emptied, and picked up by the player for placement and use elsewhere.

Loot
It contains one rare item and any amount of common items.

History
No longer requires a Hammer to pick up; it now needs a Pickaxe or Drill instead. Contains some items previously dropped by Underworld enemies.
