What if Aetherial Manipulation was altered to a trait.
Now if you hit a movement key during a cast, you move yourself 5 yalms in that direction instantly, but don't interrupt your cast. If a ley line is active under you when you do this, the leyline moves as well. This effect can only be used once per cast time.
On top of being useful, I think it would look pretty cool to go bopping around like that.
I would say that it should have a 'safety feature' though, that it stops at the edge of a cliff, so that you cant toss yourself off titan just because your controller decided to be overly sensitive.
