Strongboxes are a special type of loot container found throughout Wraeclast first introduced with the 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. Monsters not directly summoned by the strongbox, such as Spitters emerging from Shield Crabs, or raised undead, do not need to be killed to unlock the strongbox.
Strongboxes come in different base types which determine the kinds of items that can normally be obtained from them. Modifiers can further alter the loot contents, such as granting additional rare items or gems.
|Arcanist's Strongbox||Currency that do not affect quality|
|Armourer's Strongbox||Armour, Lua错误：callParserFunction: function "#varexists" was not found。|
|Artisan's Strongbox||Currency that affect quality|
|Cartographer's Strongbox||Maps, Lua错误：callParserFunction: function "#varexists" was not found。|
|Gemcutter's Strongbox||Gems, Lua错误：callParserFunction: function "#varexists" was not found。|
|Jeweller's Strongbox||Amulets, Rings, Belts and Jewels, Lua错误：callParserFunction: function "#varexists" was not found。|
|Large Strongbox||Assorted items (increased quantity)|
|Ornate Strongbox||Assorted items (increased rarity)|
Like chests, increased Item Quantity from gear does not increase the number of items dropped from a strongbox. However, map quantity and the number of players do increase the number of items dropped from most strongboxes. The only exception is the Cartographer's Strongbox, where the number of players does not increase the amount of map drops.
Like items and monsters, strongboxes come in different rarities with various modifiers. A non-normal strongbox must be identified with a Lua错误：callParserFunction: function "#varexists" was not found。 to reveal its modifiers. It is also possible to craft strongboxes using currency items. Corrupting a strongbox with a Lua错误：callParserFunction: function "#varexists" was not found。 may corrupt some of the loot contents.
Prefixes can make the ambush encounter more dangerous by releasing additional monsters or springing traps.
