You can enhance the equipment ability through Upgrade.
The 'Armor Upgrade Scroll' can be acquired through Quests, Events or by spending Diamonds.
① Tap on 'Upgrade' .
② The 'Armor Upgrade Scroll' will be selected automatically.
③ Reinforcement materials may be used or not. If the reinforcement fails, it prevents the reinforcement from downgrading.
④ Proceed with the Equipment Upgrade using Gold.
⑤ If the Equipment Upgrade is successful, the equipment ability will increase.
⑥ If the Equipment Upgrade fails, the upgrade will be downgraded instead.
However, If you use the 'Upgrade Aid', you can prevent the Equipment Downgrade.
