Reunion
After realizing the potential in his Materialization, Theo's hunt became more effective. He didn't even care whether the monsters attacked him together or not.
He refined his Materialization even more and kept using it at every chance, progressing his mastery by leaps and bounds.
The first problem with his Materialization was the excess energy. At first, he poured all the energy and formed a spear and thought it was the end.
He soon realized that at least half of the Magic Power he released couldn't be shaped properly.
It was clear what he needed to do. He practiced his Control like crazy while fighting the monsters.
The urgency of using his Magic Power forced Theo to become even more focused or he would be beaten up by the monsters.
This training was brutal because he could die at any moment. Luckily, his clone was helping him fend the monsters most of the time, allowing him to increase his proficiency.
