I'm rereading the novels in anticipation of "Peace Talks". Ms. Asher just rocked the Gate of Fire.
“She’s redirecting the energy,” I said. “See how when the waves hit her, they bounce off, all swirly?” He grunted. “She’s taking the heat and turning it into kinetic energy as it reaches her aura. It’s impressive as hell.” “So far,” Grey said. “But why do you say that?” “Because it’s hard to deal with that much heat, when you’re immersed in it,” I said. “She’s not just stopping it at one point. She’s dealing with it from every angle, and she’s got to be doing the same enchantment about a dozen times at once to stop it all, in successive layers.” “And that’s hard?” “Tell you what,” I said. “Why don’t you go play Simon, Concentration, checkers, chess, solitaire, Monopoly, Sudoku, Clue, Risk, Axis and Allies, poker, and blackjack all at the same time, while counting to twenty thousand by prime numbers only, standing on one foot and balancing a Styrofoam cup of hot coffee on your head.

So she is much better at pyromancy then Harry. Much like Mort is better at his stuff then Harry. But the rules for refinements seem to enforce that a wizard gets better if he has control over more elements - because to get specialization boni, he needs to create a column: Ie: To get a +3 in Fire control, you also need a +2 (maybe in Fire power) and a +1 (in a different element).
So if I would build Ms. Asher, she would be worse then a wizard because she simply could not take a similar amount of refinement stunts.
Any idea on how to change that?
