Upgrade System

+With the "Extended Upgrade System", you can upgrade your equipment and weapons up to +20 with better stats! At levels 13, 16, 18, and 20, you will also receive an additional diamond slot each.
To upgrade, you need Scroll of UProtect (Ultra), which you can exchange at [Cash Shop] Laura in Central Flarine, and Ultra Sunstones which you can farm in Les Britannia, Abyssal Cove, Aminus, and Cursed Aminus (exchange at Dungeon Exchanger for chips).
Note: The chance to upgrade your items is lower than from +1 to +10!
