Re: Experience and Character Advancement
The powers class is, I think, going to give some chance for people to do that sort of thing (expand). And probably give some folks a chance to showcase stuff that they can do but haven't demonstrated.
The way powers work in Aberrant is all dependent upon the perception of that specific nova. Just knowing that you're channeling quantum power is great and all, but most characters don't really see that, in spite of being told it point blank. They just know that they 'eat fire' or 'can fly' or something similar.
My own character is a great example. He knows (probably better than anyone with his Mega-Int and physics background) that he is channeling quantum forces to achieve specific affects. But when he goes to use his powers, its all gravity. He may know that he's channeling quantum no a conscious level, but his subconscious is breaking it all down into gravity. His mega-atts aren't something he consciously recognizes, so they're a bit different. They simple represent a transcendence of the base human physiological model into something a little more (well, mostly, a few of them are still 'gravity', particularly the physical ones). Most any of the 'invisible' powers that I pick for Gravitas (mega-socials and mentals are prime examples) are based on his mega-int. He understands more now - knows how they work. Or, in the case of Mega-Perception, he really can just see gravity.
Anyhoo, the point is that power growth is intended to represent a logical extrapolation of the character's starting abilities that are all - at least in the character's head - related. The book suggests that entirely new powers should be gained after maxing to try to use the power a few times (rules for power maxing are on pg147 of the core book)
