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."
The only way Leon could think of how to do that would be to keep himself holding something rich in mithril at all times. However, until now, he didn't find mithril lying around, and considering his past experiences, Leon would be a fool to wait to found such useful things. The only option left was to create mithril or stay close to monsters in order to use Mana Absorption.
"I will worry about such problems later... the shadowy figure probably is a persistent bastard. However, even he won't bother me all that much once I counter his actions a few times... probably."
Anyway, Leon had to learn the spell and worry about such things later. His first idea of how to learn the skill he wanted was to improve Mana Barrier. Leon activated it and confirmed that it could counter the heat of the magma and even the cold. Leon already knew that it could counter poison, but now that Leon thought about it, it didn't counter gravity when he learned it. He didn't feel all that much the effects of the gravity under the city of Miebos because his Gravity Resistance was high and because he got physically strong.
"This spell has to active automatically in case something happens, but it would be a pain if it blocks the entrance of even oxygen... I have to use Mana Barrier to counter the heat of this creature automatically, since that is emitted thanks to the mana of this creature, if I succeed in doing that, then..."
After learning that, creating a sphere and thickening that mana in it was easy; however, creating the same layer of mana instantly was very complicated. When Leon learned Mana Armor, Mana Shield, and Mana Barrier, he didn't have to worry about the speed... it was like he returned to the moment where he learned the basics of offensive magic.
"Even that isn't enough... the mana has to be thick enough even to counter things like Gravity and Telekinesis, the problem is... how do I hell do that?"
Leon thought that it would be hard to find an explanation of how to do that, but that hadn't been the case because he already knew the logic behind Telekinesis and Gravity. To counter those, he just had to do revert those effects using his mana. Much to his surprise, it didn't take long for Leon to obtain some helpful feedback.
Congratulations! You have learned the skill: Anti-Telekinesis Field.

"Hehehe... now I know what do I have to do."
It wasn't much efficient, and it could only counter Telekinesis. Still, since that kind of skill would only consume his mana if someone tries to control his body using Telekinesis, it was handy nonetheless. Leon had to use mana to use Telekinesis and to counter Telekinesis, but he ended up leveling up his new skill quite a bit.
Congratulations! The skill Anti-Telekinesis Field has leveled up.
You obtained 01 status points.

Doing the same thing, Leon learned Anti-Gravity Field. However, would both of those be enough to counter forced teleportation? At least, in theory, the answer was yes since Telekinesis and Gravity were used by mana on their purest form. Teleportation was probably the same thing, at least Leon thought that was the case since Transfer worked like that.
"Wait a minute... If I can do that with Telekinesis and Gravity, then..."
Leon focused on emitting his mana to his surroundings as fast and violently as possible. Much to his surprise, he soon obtained a notification but opened his eyes widely when he felt those effects.
Congratulations! You have learned the skill: Anti-Mana Field.
You obtained 01 status points.
"Oh, boy... I thought this would solve all my problems, but this is quite scary."
Just like when Leon uses Mana Concealment, he couldn't use spells when Anti-Mana Field was active. However, the skill was much complicated than that. Leon couldn't use mana, and he could block magic attacks as long as he has mana, but he also couldn't feel the effects of his passive skills. It was a skill that made him turn into an almost ordinary human again...
"This skill will certainly prevent forced teleportation, but while I fight, I will have to deactivate the skill, and that will give the chances to my enemies to use Teleport and summoning again... I can never catch a break."
It was a bit too much to hope that Leon could learn spells and then solve his problems just like that. However, he couldn't help but feel like he just learned something that could cause many problems in the future for him. Although Leon solved one of his issues quite fast... he only felt like sighing.
"I guess speed is the answer to everything... if I become fast enough, I won't have to worry about such problems."
