Leon already knew what he needed, a spell that could counter any spell that may change the space around him or force him to move. Such a spell wouldn't only counter teleportation. It also would counter Telekinesis, Gravity, and skills like that. The plan to be fast enough to evade those was a good one, but a bit unrealistic. Leon couldn't keep himself focused at all times to dodge such spells, after all.
"Fortunately, I have a terrific source of mana with me. So, I don't have to worry about the cost of mana to learn such spell... the problem later will be how I will keep the spell active every single moment. And it if was a spell that consumes my mana to prevent such attacks, for how long I will be able to counter? Those are good questions, which I can't answer right now."
