Every player has 100 CPU.
Power banks do not hit the attacker creep back.
Power spawns can be built starting from RCL5, and their construction costs 10000 energy.
Power processing cost reduced to 10 energy per 1 power.
Spawns count reduced to 1 spawn per room regardless of the room control level.
Energy source capacity is doubled in every room with a single energy source.
Players with the most processed power win the season rewards.
