As you play Path of Exile 2, you’ll inevitably pick up a lot of equipment you can’t actually use. Most often, you’ll find equipment that’s simply of the wrong type for your current character class. You can sell it, deconstruct it using the Salvage Bench, disenchant it with the help of certain merchants, or transfer it to another character using the stash. These all help turn items you don’t need into more utilitarian ones, but don’t cover every possible type of useless loot.
