1. Can you clarify what constitutes as a low or high amount of energy? Creating permanent objects is quite powerful, so I'd like to be on the same page as far as the limitations of her power.
I was kind of avoiding getting too technical about the powers because this setting is kind of magicky and there was already so much text in the character sheet but I guess I overdid it. The concept behind the powers is this: low-power can be done in the background, medium-power is a normal action, high-power actions are used sparingly or in emergencies, and very high-power is used as a kind of ultimate ability (I should call it "extreme" power usage, come to think of it).
2. As an extension: How much of this power is held in the batteries? I imagine you would only consider using them in an emergency.
When activated and when not using any powers (besides the ones that are auto-activated by the battery), a battery will last for 24 hours. An extreme-power ability like Create or Energy Blast uses up an entire battery. They are indeed only for emergency use.
3. Body Energy Manipulation: How does this work if the suit is tapping into her bodily (I'll just call it metabolic) power? If the suit is using the power, would that not incur the side effects this power is meant to mitigate?
Metabolic! Thank you! I've been trying to remember that word for days now! As for your (second) question - not really. You know IRL how you do a massive amount of exercise one day and the next day your muscles are all sore, regardless of how much food you eat? That's what the ability targets. It decreases the rate at which muscles get sore so you can sprint for longer but decreases long-term movement range.
4. Text-interpreter/Map-reader: Since the entire earth is now effectively host to the ruins of countless worlds, once inhabited by innumerable creatures of varying genealogies, I can't say these abilities are feasible. However, we can easily fix this problem by changing it to 'Aoen Intuition' or 'Connected to the Past' or something like that. In game, this would make use of these skills less like vague interpretations and more like gut feelings.
Sure. I was just guessing at what kind of skills a scavenger would have. I have no problems with changing some of those skills but I don't know how to write the descriptions for the ones you suggested.
EDIT: I forgot to mention this in this post initially, but high-power and extreme-power abilities are physically painful/harmful unless using a battery as the energy source.
