[quote=Mr Allen J]I'd say any energy she re projects should be of a lesser output than what she's received it. Also, we do not have a scale for attacks. So technically it'd be hard to measure what would be an "attack above level 6"

It's not explicitly stated in the CS, but that would be the case as the power is explained right now. Any of the energy that causes damage to her in the process of absorption would by necessity be used up doing it, so even when she's actively absorbing it there would still be a portion of waste that she couldn't redirect back outwards. If she was absorbing fire, for instance, a portion of that energy would escape her control during the channeling process and cause damage to her body, so she would either have to release the remaining energy in a weaker version of the attack it hit her as, convert it into raw negentropic energy to store or use for enhancement, or boost it with a portion of her previously stored energy.

So it's not a perfect conversion by any means. Even when she's actively absorbing, a portion of the energy directed at her is lost. If you want an exact amount, I'd say it would start at around a 40% loss when she first learns she can absorb energy, then that would decrease as she gains more skill in it, though never to the point of perfect conversion.

As for the power level of an attack, I'd imagine that "an attack above level 6" would be what happens when a level 7 energy projector pushes themselves to the brink of ashing (without going over).
