Upgrading your equipment requires the use of Sunstones. Upgraded armor pieces provide more defense. Fashion pieces that are obtained from the Cash Shop; however, cannot be refined. The (+x) shown at the end of the upgraded equipment signifies the refinement value; with +0 (none shown) being the lowest and +10 being the highest (for general refinement).
How To Upgrade Armor (Unsafe)
Please note that this method is guaranteed not to fail for upgrading TO +3 or lower. Attempting to use this method on an item that is +3 or higher has a chance to fail, in which case the item may break.
(optional) Place a Scroll of Smelting next to the Scroll of SProtects to increase chance of success by 10%.
Upgrading past +3 has a chance of failure. The higher the upgrade, the lower the chance of success. Upon failure (starting from +3 onwards) your weapon/armor piece and the Sunstone used will be destroyed. You can avoid the destruction of equipment by using a Scroll of SProtect; a Premium Item which is available from the Cash Shop. They protect the equipment piece from destruction if the upgrading attempt fails, but they are consumed regardless of whether or not the upgrading succeeds.
Additional set bonuses are provided if a full armor set is refined to +3 or higher.
There will be a glowing visual effect surrounding a character with an armor set which has a refinement of +3 of higher equipped. The image below demonstrates how the armor glows look like; from +1 to +10.
