Introduction[]
Upgrade Cores are a type of Core used for increasing stats on armor, weapons and bikes. The +X after the name of an item indicates how many times it was successfully upgraded. Eg, "Titanium Blade +4" has been upgraded 4 times.
Usage[]
If you've never used an Upgrade Core before, you are best to practice with an Upgrade Core(Low). Be aware that the stat requirements of the item will increase when you upgrade it.
- Unequip the item you are upgrading
- Left click on the item upgrade button in your inventory, and insert item and Upgrade Core (Low)
- Left click on "Item Upgrade"
- If successful, the item will now be +1 (or more depending on the original grade of the item), in a very few situations, the item is upgraded with +2

Core grades[]
There are 4 grades of Upgrade Cores. Each grade is used to upgrade different grade of gear and weapons:
| Image | Item name | Equipment Grade |
|---|---|---|

Upgrade Core (Low) |
|
|
Upgrade Core (Medium) |
|
|
Upgrade Core (High) | |
|
Upgrade Core (Highest) |

Chance of failure[]
- When failing an item upgrade the item is never destroyed however its upgrade level may drop by 0, 1 or 2.
- Using Enhanced Cores exclusively guarantees a success chance of 100% but only to +6. Beyond that, when using enhanced cores exclusively the item level may drop no more than 1 if the upgrade fails.
- Perfect Cores guarantee 100% chance of upgrade at any item upgrade level. Only 1 perfect core is needed regardless of the number of cores needed to upgrade.
