Energy is the main Campaign resource.

You need Energy to complete missions in Campaign mode or to pass them instantly with Memory Spheres.

Energy restores itself over time at a rate of 1 per 6 minutes (10 energy per hour).

Energy limit increases with every new level. You start the game with 60 energy limit, you gain 1 additional unit from every level-up, capping at 140 Energy when reaching player level 80.
