Strongbox

A strongbox

Strongboxes are a special type of loot container found throughout Wraeclast in Ambush league. 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 relenquish its loot. The monsters released by a strongbox also drop loot and grant experience when killed.

Loot

Strongboxes come in different varieties which determine the types of items that can normally be obtained from them. Modifiers can further alter the loot contents, such as granting additional rare items or gems.

Version history

Version	Changes
1.1.1	Fixed a bug where the Strongbox mod that drops additional magic or rare items would have no effect on Maps. Fixed a bug that could cause monsters spawned by the Strongbox stream-of-monsters mod to behave strangely. Fixed a bug where Jeweller's OrbJeweller's OrbStack Size: 20Reforges the number of sockets on an itemRight click this item then left click a socketed item to apply it. The item's quality increases the chances of obtaining more sockets. would not prevent you rerolling an item that had more sockets than it naturally could have at that itemlevel, due to dropping from a Strongbox with the increased sockets mod.
1.1.0f	Fixed a bug where the Strongbox mod that dropped additional magic or rare items would not always drop the correct number. Fixed a bug where some mod restrictions on Strongboxes would not work (for example, quality mods could erroneously spawn on Jeweler's Strongboxes). Fixed some cases where atypically few or many Strongboxes could spawn in some areas.
1.1.0e	Reduced the number of Maps dropped from Cartographer's Strongboxes.
1.1.0d	Made further improvements to the spawning of Strongboxes in narrow areas like caves. Halved the spawn rate of Gemcutter's Strongboxes in the Ambush league.
1.1.0c	Monsters and Rogue Exiles spawned by Strongboxes in the Ambush league now drop items and grant experience when killed. Fixed several of the cases where Strongboxes could block physical passage through a level.
1.1.0	Various new types of 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. Sometimes you'll encounter magic, rare or unique Strongboxes which have mods like items do. Prefixes affect the difficulty of the ambush by adding more monsters, springing traps or affecting your character. Suffixes improve your rewards from the Strongbox. You can use currency items to reroll these mods. One of the new challenges is to open Strongboxes with each mod.
