Strongboxes

Special chests, called Strongboxes, can be found throughout Path of Exile. Unlike ordinary chests, Strongboxes are protected by monsters that must be defeated before the Strongbox will relinquish its treasures. Although Strongboxes are not technically items, they do share some special traits in common with many of Path of Exile's items. Specifically, Strongboxes have mods and, like items, these mods can be changed with the use of currency. There are several different kinds of Strongbox to find, each one providing different amounts or kinds of items. Here are a few of the more common ones:

It is often worth carrying some currency items with you, so you can modify any strongboxes you happen to come across. The difference between a normal Strongbox and a well-crafted magic Strongbox can be quite significant.

Your Stash

While out in the wilds of Wraeclast, you might've run out of bag space and found that you couldn't pick anything else up. Luckily, every Town and Hideout in Path of Exile comes with a stash. The items you put in your stash can be accessed wherever a stash can be found. You'll find the same items you stashed in Lioneye's Watch waiting for you at the Forest Encampment, your Hideout, and anywhere else with a stash.

In fact, all your other characters in the same league can also access the same stash, so if you get a great bow while playing your Marauder, you can stash it to use on your Ranger later.

Expanding Your Stash

At some point you may find yourself running low on stash space. Extra stash tabs can be bought in the Microtransactions shop, and once purchased, will be available in every league. They come in a few different varieties:

All stash tabs have a search bar at the bottom that lets you search for and and filter out items, so you can quickly find what you are looking for. The items in your stash never go away. However, when a temporary league ends, all the items in your stash will be moved to the stash in its permanent equivalent. When this happens, your items can be found in stash tabs labelled "Remove Only". These will hold your items indefinitely, but anything removed from a Remove Only tab can't be returned to that tab.
