Kyle's team trained a bit more before they took on the next mission.
The Spellcasting training would take a long time to bear any fruit, and Kyle couldn't just spend weeks on end doing nothing but practicing Spellcasting.
First, Kyle had to be able to conjure different amounts of Ether down to an error margin of only a single Miz.
He needed to be able to conjure about 350 Miz worth of Ether for the temporary enchantments he wanted to use, and whenever he tried to get there, he summoned anything between 310 and 400 Miz.
While using techniques, it didn't really matter how much Ether one summoned.
Since the techniques were all created in one's body, the surplus Ether would just travel back to the Center, essentially not wasting anything.
So, Fighters just summoned more Ether than necessary and just pushed the surplus back.
Spells didn't work that way.
