Fire's touch flare's limitations

Flare Valence, Fire's touch:
{subject}'s limitations and abilities in this shape;
first of all, he cannot make fire behave in a way not possible according to the laws of physics (say, make it cold and soothing to the touch, and not burn you)
he cannot, continuously push out flames out of his "domain" without his complete focus, this action also leaves the created "barrier" just inside of his "domain" relatively weak, as targeted streaks of fire (test made use of a flame-thrower) go through his "barrier" with ease, further making him lose his focus
he, cannot create more air to fuel the flame, or keep himself with a steady amount of breathable air (almost caused the cessation of {subject}'s functionality, further fire-based testing ceased for a period of 75 days)
