The only unfortunate part, and the reason Dyon wasn't able to quickly defeat Berolt despite this truth, was that the Dark Flame world and the desert world were two sides of the same coin. Dyon had already said that he shouldn't absorb the same types of energies, yet he had been faced with yet another fire/ice world core.
Knowing that he couldn't, Dyon had no ability to improve the strength of his body. Due to his constitutions, his body was the most foundational part of his strength. As a result, despite control half-laws more powerful than even some laws, he still had to be cautious.
His main goal now would be to find another source of energy so he could balance out his body with more energies.
