There are three ways to improve the strength of items in Diablo 4, namely upgrading items, adding inlays, and enchanting. Through these three methods, the strength of items can be upgraded. After upgrading, you will have greater advantages in battle.
Upgrade items
The first is to upgrade the item. After the upgrade is completed, the power of the item can be increased by 5 points, up to 25 points.
The cost added in each upgrade is different, and the weapon can be upgraded up to 4 times.
Add tessellation
The second step is to add inlays to the items. After adding them, you can get additional rewards.
The added props are generally obtained from the world bosses, and only a small amount are obtained from enemies.
Enchant
Enchanting allows you to re-obtain affixes on items, so that you can get better attachments.
It should be noted that this is limited and can only be added to each item with a spoof affix.
