Energy is needed to fight in the battle mode. The stronger the enemy is, the more energy is needed to fight him. Like electricity, it adds durability to the game. Effectively paying your energy points is done in PWR tokens and allows the token to circulate.
For example: In tier 4 the most powerful enemy requires 36 energy points per fight.

How it works:

You have a maximum of 250 energy points per mining room. You can choose how much energy you want to fuel. You have to be strategic. How fast you'll spend your energy points depends on the tier you're fighting in.
1 Energy is equivalent to 1 BUSD.
