Herm I see, I see.... I suppose I shall make a character that is trying his best to receive and give energy, so he'd be focusing on becoming more like a battery. Where, in a fight, he'd be that support class that makes everyone around him stronger by sucking in heat, light, etc., transforming it to mana, and then sending it out to the others so they can use their more powerful abilities to do things. Or, alternatively, to drain the energy from enemies to use for mana. If possible.
