- This article is about Nightfall chests. For Eye of the North NPCs revealed by the Light of Deldrimor, see Hidden Treasure.
Opening treasure yields both a single item (dropped on the ground) and some gold (added directly to your character's inventory). The item will be either a gem (diamond, ruby or sapphire), weapon, or salvage item (of purple or gold rarity). As with other loot, the values increase as you progress through the game. The cash values increase with each successive region, from about 500 in Istan to 3,000 in the Realm of Torment. A player might expect to receive 20 if they open every treasure. (However, these values decrease as you reveal each treasure; see Notes for more information.)

- Treasures are always unlocked. Neither keys nor lockpicks are required.
- Treasures labeled Do Not Touch might be guarded by several hidden Immolated or Ruby Djinn that will popup when the treasure is opened. Spread your party out before opening to avoid their dangerous area of effect skills.
- Treasure quality
Treasure quality is the amount of cash and the chance of getting a gold item. The factors governing quality are not entirely understood; however, the following properties have been well documented:
- Cash values are linked to the rarity of items found: purple items are found with about ⅔ the cash of that found with gold items.
- Quality decreases permanently for a character each time they reveal any treasure.
- The lower cash limits appear to be as little as 100 in Istan and 700 in the Realm of Torment.
- Scaling of the rewards only kicks in after a particular number of treasures (significantly more than three) have been revealed.
- Hard mode does not appear to affect the values.
- Treasure availability
Each character can receive loot only once during a certain period, believed to be around 30 days per treasure. Opening the chest too soon means that there will be no treasure; some evidence suggests that this resets the waiting period.
