So I have a modern setting with psions. Their powers fall into groups that control different well defined things, with many controlling fundamental forces. The psions' powers automatically attempt to protect them from known threats so someone who manipulates kinetic energy would be able to stop bullets easily. Similarly electromagnetic control would stop bullets in many different ways (for instance vaporize it with a laser in midair).
However this power system sticks some unlucky people with control over the strong or weak force. Psychics have limits over how much energy they can generate so someone couldn't just disassemble an entire object with the strong force, because of how much bond energy would be released or taken, in fact pretty much any use of these forces on the macroscopic scale has the same problems. Given the short range of both these forces it seems to me that a psion wouldn't be able to to do much more, than bathe the area with radiation with either of these powers. I'm not even sure a psychic could use this power to protect themselves from that radiation either. Psions can for the most part only influence areas they can see, and can't do stuff to the interior of an object but not the exterior, since they can't see it.
So what exactly could someone do with one of these powers? Applications that would be actually be likely to come up in a RPG or story are more preferable than extremely niche uses. Power is limited by sight range, so maybe the psion could avoid radiation. But still compared to what other powers can do, these don't seem that great (hell, several other powers like EM control can also release radiation like this).
So what is a weak-force, or strong-force psychic to do? In addition, is there a way to use either of these powers to protect yourself from the radiation produced by the powers themselves, or anything else for that matter?
