There's already a healer, but a nullifier might be difficult to work with in the long run. If I were you I'd take a look at the characters already in place and ask myself, "What can I make that the rest of these crumb shitters won't expect?"

This.

The problem with active power nullification is that it can be easily abused and might inspire arguments to sprout out of a complicated scenario that can be difficult to presume what may necessarily happen in reality. Those situations leave a lot up to conjecture. It wouldn't necessarily bother me, since I'm constantly poised to bitch-slap a mother fucker aimed at "winning" in a roleplay, but I don't really have the energy to manage that or even watch it occur. Another issue is that it can be abused. It is hard to say.

Building off what Maxwell had said, an out of the box idea, 9 times out of 10, turns out to be fairly fascinating and makes me eager to see how it plays out.
