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 a map mechanic. 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.

Corrupting a strongbox with a Vaal Orb results in all items being Corrupted.

Version history

Version	Changes
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.
