Power Ups are used in both PvP and PvE and can be used by double-clicking them in your inventory. They provide players with bonuses such as HP or other Stats. However, the reactivation System provides an automatic way to re-use these power ups once the power up duration has completed.
This can be accessed through Start -> Systems -> Automatic Powerups.
Players can place Power Ups in any of the 8 windows and select the 'Activate' button to proceed with automatic consumption. The easiest way to place Power Ups in the system is to simply click on an unoccupied field. This will open a dropdown menu with all possible Power Ups from your inventory or powerup bag. Pressing the blue buttons either deactivates or activates all powerups, the black button activates all powerups on that page only.
