When you perform an energy attack, you may choose for it to do the same amount of power stages of damage to any personality, instead of dealing life cards of damage.
I know exactly what I'm up against.
Errata:
You choose whether the attack will have all of its Life Cards of damage converted to power stages when you perform the attack, but you do not convert the damage until after you have calculated how many Life Cards of damage the attack would deal (after all other modifiers). This does not create an infinite loop with Energy Empowerment Drill.
