I think compared to controlling natural disasters or elements it is. For instance, if your character decides to throw a tornado at me, there's not much I can do about it. In that case it would be a battle of who can hold out the longest and I would lose. If Stryder decides to shoot a bolt of lightning at me there is even less that I can do, since summoning lightning would cost less energy than creating it himself and my character would run out of energy before she could get enough time to place a hit on him. I'm just looking at this realistically and the odds would be in your favor, not in mine, unless the battle was in complete and utter darkness.
But okay, forget I said anything. Was lunar energy allowed or should I edit that out and put something else there?
