How to Upgrade The Enhancements?
To improve the weapon upgrade you must go to Maker’s Forge and talk to its guardian. Select the appropriate option and go to the Upgrade screen. On the right-hand side you will see the type of enhancement and 4 stages of upgrades. In order to perform an upgrade, you need to have the appropriate items. It’s worth mentioning here that when upgrading you only need to take one path (Angel or Demonic), and at the very end you will receive all possible bonuses anyway.
