How do weapons in Diablo set gems?

1. First, we need to find an NPC craftsman in the game.

2. After we go to the craftsman again, click on his body, jump out of the option box and choose to build.

3. After entering the interface shown below, we choose enchanted equipment.

4. It is possible to wash the mosaic holes by decomposing the materials obtained from the equipment to wash the attributes.

5. After washing out the mosaic hole, click quickly to replace the attribute. Then our equipment became perforated.
