[@AlternateMan]I know it’s not. I apologize if I gave the impression I was going to treat it like it was.

 I was going to treat it like a mana/stamina sort of thing. The more she uses it the more she’ll wear herself out. Also she cannot expend all her energy at once. Shields are easy. It’s just making a wall. Walls don’t move, but she has to use energy to maintain it. Projectiles are harder since she has to make it and then exert enough energy to ‘throw’ it. The gun helps with the throwing part. So the more rested she is, the longer she can fight. As for what that limit is, I don’t know yet. I don’t want to make her over or under powered during whatever is considered an average or even a learning battle.
