Upgrade weapons

1. By visiting the weapon upgrader, you can add one yellow affix to your weapon, and you can add up to three yellow affixes.

2. It is worth noting that two of the affixes have negative effects, namely "Attack restores 1 life point, damage is doubled" and "Weapon damage is 200%, damage is doubled".

3. The cost of upgrading will increase step by step. The first upgrade costs 70 yuan, the second time 140 yuan, and the third time 210 yuan.

The above is a guide on the location and enchantment of Yuan Neng's out-of-control weapon upgraders. I hope it will be helpful to your gaming experience.
