[@Wick] There's still the issue of being able to land everything she aims. Like I said before, that's impossible, because even deadshots miss. 

I also just realized she started to practice [i]after[/i] the war... the war was fifty years ago. Which means she should be 50+ years if she started after the war like you said. That also voids the mages killing the people in her village, since again, the Holy War was fifty years ago and there haven't been any wars since. 

You say she studied combat from 10-14 years. That's a reasonable amount of time, but is there a reason she stopped? Soldiers study combat even though they may be experienced warriors. Practice makes perfect. :)
