# 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](/custom-content/shiny/les-britannia.md), [Abyssal Cove](/custom-content/shiny/abyssal-cove.md), [Aminus](/custom-content/other/starter-dungeons/aminus-cursed-aminus.md), and [Cursed Aminus](/custom-content/other/starter-dungeons/aminus-cursed-aminus.md) (exchange at Dungeon Exchanger for chips).

**Note: The chance to upgrade your items is lower than from +1 to +10!**
