Chest

Locked Chests
The landscape of Tyria is dotted with randomly positioned locked chests, which are guaranteed to contain uncommon or better items. Whenever your party finds a new, locked chest, multiple party members can each use their own keys to unlock the chest and get their own loot. Monsters randomly drop chest keys, and you can also buy chest keys from Merchants. Chests differ in regions and can only be unlocked with the appropriate key.

Unlocked Chests
In Pre-Searing, players will find lots of unlocked Hidden Stashes. But Post-Searing, unlocked chests are very uncommon now.

Any player can open an unlocked chest and it will drop gold or several items of loot designated for some among the party. As such, if one is adventuring with henchmen, it is possible to open the chest and get nothing because the loot was assigned to the henchmen.

Examples of areas that still have unlocked chests include Icedome and Dreadnought's Drift.

Note: While doing the quest Kilroy Stonekin, Sorrow's Furnace will produce three unlocked chests. These chests are not normally part of the area and will not be there without that quest.

Mission/Quest Chests
Several quests include chests (e.g. the quest "The Royal Papers"). These are unlocked and reveal quest items when opened.
