Energy System is the base of Soulworker Gameplay. Each character has its own Energy bar located in the right-bottom of the screen that is consumed everytime you enter in an instance.
The energy cost of the instance depends on how depth it is in its portal and also can vary depending on the difficulty chosen in some cases as in raids.
200 Energy are recovered everyday, plus energy from past day if you played that were not used are saved half of it.
Energy can also be recovered by others ways, there are items ingame that let you recover instantly points of Energy but their uses are limited every day, this items can be bough from gruni shop. There are also "community items" that players can use and some energy will be recovered after some time interacting with the item, those items can be an radio, picnic, etc, Any player can interact with an community item spawned by another player if there are free space.
If you have an premium membership active you get more energy every day and also a chance of getting items for recover a lot of Energy.
Energy Points aren't shared among characters. This means that you can farm instances with different characters without problem.
