Strongbox

Strongboxes

Tooltip

Strongboxes are locked chests that contain various items.

Attempting to unlock a Strongbox will unleash packs of monsters that must be defeated in order to get the items within.

Strongboxes can be modified to increase the difficulty and reward of the monsters and rewards within respectively.

Strongboxes are an encounter found in both the campaign and endgame. The exile may encounter chests with varying rarity, including unique. These chests may be crafted upon with currency items. When the chest is opened, a dark mist will surround the character, and monsters will approach. After they are slain, the chest will open and drop its rewards.

This mechanic is extremely similar to a Path of Exile 1 mechanic of the same name.

Version history

Version	Changes
0.2.0g	Strongboxes have increased Item Quantity and Item Rarity, guarantee a Rare item as well as getting a further +50% more Item Quantity and Item Rarity in Cruel, and +100% more in Endgame. Researcher's Strongboxes will now have a much higher chance to drop Rare currency instead of Magic currency. Reduced the variance in the number of items Strongboxes dropped. They should more consistently drop a good number of items.
0.2.0e	Strongboxes now pause Delirium fog when they are opened, in addition to the pause they already had on completion.
0.2.0d	The Rain Festival Beetle now has Drops 3-5 additional Jewels (from 5-7) and 100-150% more Rarity of Contained Items (from 50-100%).[Undocumented]
0.2.0	Introduced 4 Unique Strongboxes - special chests with unique encounters. Strongboxes now spawn slightly more packs of Monsters in Maps. Strongboxes can now appear in certain Act 1 areas. (Hotfix 4) Monsters spawned from Strongboxes can no longer be Spectred.
0.1.1c	Added Minimap Icons for Strongboxes.
0.1.1	A number of Maps now have 50% more chance to contain Strongboxes. Maps that are only exclusively found in Biomes containing Citadels now have 50% more chance to contain Essences, Strongboxes and Shrines. Strongboxes have been adjusted to spawn waves of enemies over a much shorter period of time. The Strongbox fog effect now fades away once all the waves of enemies have been spawned. Significantly increased the chance to encounter Research Strongboxes. Added a visual effect to distinguish which Monsters have been spawned by a Strongbox. The Volcanic Crag, Lightning Storms, Ice Spikes and Chaos Barrage Strongbox modifiers have all been adjusted to activate after a delay. Fixed a bug where strongboxes could fail to generate any monsters.
0.1.0f	Fixed a bug where Rare monsters could pause Delirium mist for an extended period of time, even before touching the Mirror of Delirium. This could result in opening a mirror and having no monsters spawn, or the mist not expanding fully. In addition, Delirium mist is now paused for 10 seconds when opening a Strongbox (previously 5). Note that unrelated to Delirium Mist, further changes to Strongboxes will be made in an upcoming patch to make them less terrible.
0.1.0	Introduced to the game.
