Open a Unique Strongbox
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. The monsters released by a strongbox also drop loot and grant experience when killed.
