Open Strongboxes (0/120). Strongboxes are a special type of chest found throughout Wraeclast. When opened, a strongbox will release groups of monsters to surround and attack the character. Only once all of the ambushing monsters are slain will a strongbox relinquish its loot.
Open a Unique Strongbox. Like most other unique items, it is possible to craft a unique strongbox using an Orb of Chance on a normal strongbox with the corresponding base type.
