Strongbox

Special chests called 'strongboxes can be found throughout Wraeclast. These chests are guarded by monsters that ambush the player when they are opened. The ambushing monsters must be slain before the contents of the Strongbox can be claimed.

Like items and monsters, strongboxes can be magic, rare or unique with special modifiers. You can use currency items to add or reroll these mods. One of the challenges for the Ambush league is to open Strongboxes with each mod.
