Quick and Easy Questions (please read the OP)

If a power is not on the list of the Powers/Proficiencies,  would writing it as a move be acceptable, or is it impossible to use?

Not to open a whole discussion about it, but I feel like the "Powers and Proficiencies" list offers a MASSIVE open system for Moves to work with. You can create a "fodder" power, such as Firebending either using a series of moves and similar powers to create a facsimile.

In summery; call it whatever you want IC, a "Power," a "Quirk," a "Nitch," etc. OOC, game wise, you just build it out of the legos you have in the box.
