Alas, being hyped was one thing and achieving his desired goal was another...Felix ended up spending more than a week battling Selphie.
In that week, they fought over three hundred battles until Felix had literally memorized every single spell, technique, combination, strategy, and tactic utilized by her!
Only then was he able to predict every move she was about to do and plan three or five steps ahead to defeat her.
Naturally, it wouldn't have been possible if he hadn't thoroughly adapted to his twenty spells and made the best of them.
Honestly, if Selphie wanted to go all out and give her absolute best, Felix would still take much longer to defeat her.
However, she wasn't interested in the slightest in that as her main goal was always Felix's progress. Now, that she was satisfied with his lesser spells combat mastery, she could finally move on to another lesson.
