As you play , 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. What happens when you find an item that you can equip with your current character, but it's much worse than everything you already have?
Well, you can sell, dismantle, or disenchant it as per usual, but that feels wasteful. In that case, there's an alternative option: the Reforging Bench.
This unique crafting option allows you to exchange multiple types of the same item for a chance at rerolling its stats, and more often than not, the results are better than the sum of their parts.
