Unlimited Power - The Arcane Path

In the blink of an eye, a month passed, at least for Leon. Since he didn't find any other monster with interesting skills, it looked like he would have to make things work with the equipment he obtained using the mummies' spirits. Regardless, time passed really fast because instead of returning to Ilyana's world, Leon went to other worlds that were on the third stage of assimilation in order to hunt the monsters there. In fact, he only went to a single world, the gremlins' world, since their numbers were insane. Although they weren't that resilient, Leon felt satisfied hitting something that could move.

Using Plasma Arrows was overkill, so Leon decided to train other spells while he also used Thunder Ray and Ice Beam to stop them. It was hard to be sure, but Leon felt like he had killed a few hundred thousands of gremlins. At least that was what he thought after noticing that smoke on that world decreased a lot and saw the pile of demonic spears behind him.

"Looking for the gremlins is a pain now... I guess I will just learn a few more spells while I wait for them. So, who wants to teach me some combined spells?"

"Celsius and I are going to teach you this time." Undine declared.

"Why me and why both of us at the same time?" Celsius frowned.

"Can I ask to learn something more practical for battles?" Leon asked.

"Don't worry, the spells you will learn are very battle oriented," Undine smiled.

After hearing that, Leon only felt more worried. Celsius was easy to understand, but the same things couldn't be said about Undine. Regardless, both of them started to demonstrate for Leon the first spells, and Leon couldn't help but frown when a rain cloud appeared above the place, and just a few small drops of water fell from the sky. However, every drop of water created a massive spiked block of ice when it touched the ground. It was the perfect skill to defeat swarms of gremlins, but they didn't even try to help Leon.

"... Why didn't you use that to help me?" Leon asked.

"Because you had everything under control and because you didn't ask," Undine answered.

Leon sighed because she was right. Leon had everything under control even when dozens of gremlins flew toward him, he didn't ask for their help because he felt like they wouldn't agree to kill many weakling monsters. However, even though the spirits were stronger despite being at a lower level, the gremlins weren't exactly pushovers.

Complaining about that wouldn't help Leon in any way, so he could only learn his lesson and practice that new spell. Although it was a bit complicated since Leon had to create drops of water that had a lot of mana without making them turn into ice, Leon had the intelligence and control to learn something like that. It took a few days, but he eventually learned the spell.

"It isn't bad for an Area of Effect spell, even though it is slow, it can be used to surprise some enemies," Leon said to himself. "As long as I stay out of their range, it should work."

"Well, the next spell is..." Undine said with a big smile on her face and then nodded to Celsius when she saw a gremlin approaching.

Leon opened his eyes widely when he saw Undine and Celsius, pointing their hands toward the monster, and then the skin of the gremlin started to get dark. The creature screamed in pain until it completely stopped moving and just fell when half of his body became dark and lifeless.

"The hell was that..." Leon said, shocked.

"It is Frostbite. You use the water around the corpse of an enemy and freezes it," Undine said, still showing a big smile. "It is a bit difficult to control, but it is very useful, as you can see."

That was one hell of a terrifying spell. It was terrifying because Undine used while keeping a smile on her face... Regardless, the logic wasn't that difficult. Leon just had to control the water inside the enemies' body and use the power of ice to freeze that same water instantaneously.

Congratulations! You have learned the skill: Frostbite.

Leon eventually learned the spell, but he was pretty sure that some gremlins would torment him in his dreams because he used them as test subjects. The beasts were vicious, but despite that, they could scream and tremble like any other creature. Leon wasn't vicious enough to torture monsters like that just to learn a skill, but he did it because there was no other way to learn the skill.

Congratulations! You have learned the skill: Ice Coffin.

The last spell Undine and Celsius taught Leon was something far less vicious, but still pretty terrifying. Applying the same theory of Frostbite, but this time using the humidity around the target, Leon could lock most monsters inside an Ice Coffin. The spell itself wasn't that useful at low levels since it could be broken, and the damage caused by the ice was relatively small... but at least Leon learned a good lesson from that. He learned that he should think twice before asking for Undine's help. She was scary in many different ways.
