About
Arc Upgrader Items is a SkinClub-inspired item upgrade mod, that is based on Upgrade Items by EXEcheINZ.
This mod will allow you to take your current item and try to make it better through a visual upgrade wheel.
Features
- Draggable success zone on the upgrade wheel
- Ability to move the success zone freely before upgrade attempt
- Moving the success zone doesn't change the real success probability
- Rebalanced item values according to Astral version
- Better wheel position-SUCCESS/FAILED result synchronisation
- Visual upgrade system inspired by SkinClub
- Single/multiplayer compatibility
How It Works
Select the item you want to risk and the item you want to upgrade to.
Probability of success depends on the difference between values of the two items.
Before attempting the upgrade, you can move the success zone on the wheel to any place. This only moves it visually and doesn't affect the real probability of success.
Then upgrade process begins and the wheel decides whether it is successful or not.
Credits
