It is a complex multi-factor process for developing, repairing, and upgrading weapons, armor, and clothing items.
A broken item is the result of abuse of the item. We must constantly monitor the condition of our weapons, and repair them in the event of constant fighting. Otherwise, its uniqueness will drop to corrupted.
Upgrading items[]
You can view the stats of upgraded items under the Uniqueness tab . To upgrade an item, open your inventory and right-click on "Upgrade Item". Upgrading an item to the next unique level requires an item that increases uniqueness to a higher level.
Developing items[]
Item Upgrade Chance:
1-3: 90%. 100% with improved uniqueness. It doesn't get destroyed when it fails.
4-6: 80%. 100% with improved uniqueness. It is destroyed when it fails.
7-8: 60%. 100% with exceptional uniqueness. It is destroyed when it fails.
9-11: 40%. 100% with Legendary Unique. It is destroyed when it fails.
12-15: 30%. 100% with original uniqueness. It is destroyed when it fails.
Each item can be upgraded to a maximum of +15. Each + increases damage or defense depending on the item's use, by 5%. Items can be crafted with a runestone.
List of Seals[]
Seals are divided into levels of advancement, which can be increased at the blacksmith for the required number of seals of the same type. We can put one seal into an item, which will provide a different effect depending on the type. Item with + is required to seal it.
