Re: Champions of Infinity Campaign and RPG Aid!
For the setting purposes, supernatural abilities are all powered by tetrino flow.
The "Mutant signature" disad means you're pulling tetrinos all the time, but doing anything that surpasses normal human abilities means you're almost certainly pulling them for the duration of the action (and the following recoveries).
Of course, you can alway take a specialized "invisible power effects" adder if you've got a subtle power that you want to keep as a hole card.
