Open: This is the chest you got the Death rewards from.
Closed chests, or open chests when opened, can be found at the Grand Exchange near the Guardian of the Vault. Each month starting from the release of the player-owned farm (3 September 2018), gold Premier Club members can open one of the closed chests for exclusive rewards.
The first chest can be opened after completing the player-owned farm tutorial. Along with gold Premier Club members, it can also be opened by members who have purchased the Summer Special 6 month package.
