Use the following Currency in the Crafting Bench.
The Crafting Bench lets players craft a modifier into equipment or modify sockets and links at the cost of some currency. It can be found in the player’s hideout.
Typically, only one crafted modifier may be added to an item; the crafted modifier is shown in a brighter color than regular mods. Crafting a mod follows the normal affix rules. Specifically:
It is possible to craft more than one mod onto an item with the of Crafting meta-crafting mod.
Players can remove a crafted mod from an item with an Orb of Scouring. If the item already has a crafted mod, the recipe will automatically use a Orb of Scouring to add a different crafted mod.
There are also recipes which modify the number of sockets, socket colors, or links on the item. Players may use socket recipes on corrupted equipment, which will require the same amount of Vaal Orbs as the required currency.
For convenience, the ingredients/currency needed to craft a mod onto a piece of equipment do not need to directly be in your inventory at the time. The Crafting Bench will fully track, and use, items in your Stash as well.
Crafting recipes are discovered in various locations across multiple contents. Most of them can be found in the campaign Acts, The Labyrinth, and maps. Unveiling veiled items also unlocks crafting recipes.
