There is no trading of gold in Path of Exile, etc., but incredibly valuable materials prevail. These are golden crafting materials. They will be dropped by monsters, jump out of the box, and sold by vendors. In forums, these projects are usually called Poe currency Items. Most materials have dynamic value in the Exile Road economy, but can also be used to make handicrafts. For example, the Value of Regal Orb is equivalent to X Chaos Orb's value, but it can also be used to upgrade magic armor to rare armor. Of course, the result of this is that different handmade materials pack dynamic values ​​depending on their use and rarity in Exile's economy.

Handmade
Poe Currency items are used directly on the item; NPC does not apply to this item. At first, you shouldn't try to make it, and the process is complicated and random. Before testing, you should gain some experience here.
As long as you don't waste many handmade materials, it is very safe to use Grade 4 handmade materials for hand sewing. You can use the following recipes for practice, for example:
Chromatic Orb allows you to customize the color of the slot to match the necessary skill gems.
With Jewelers Orbs, you can change the number of sockets on the device (but you should pay attention to the item class of the item)
