― In-game description
A Treasure Key is a consumable that can be used to obtain loot from the Queen's Chest after completing a Prison of Elders activity. A Treasure Key can be obtained once per week by completing one of Petra Venj's bounties.
The maximum stack size for Treasure Keys is five. If a Guardian already has five keys in their inventory, additional keys acquired will not go to the Postmaster.
