Girlie has been too stubborn with learning one type of magic, even assistance magic like wind could help her fire magic, everyone has to adapt to her because her fire is reckless but she hasn't tried to refine it more. I understand she's been working on other stuff but you know how they say like if you doodle in your book everyday you can get better at drawing. If she fiddled with different magic everyday maybe she would understand a small amount of it and then figure out ways to use it efficiently
