With Taienra's and the cats' help, Toz showed steady progress in learning the Dissolution spell, even if he was still limited to dissolving items.
Toz continued practicing his magic without a care, wanting to attain enough proficiency with Dissolution to use it in actual combat. Even if the spell itself didn't add much to Toz's fighting capabilities, simply learning the spell increased Toz's understanding of void magic, which, in turn, would improve the might and efficacy of his combination magic.
It seemed like Toz's practice with void magic and training with void mana together brought Toz to the brink of a breakthrough. Since he spent the free time he got after the battle with Dristel training his void mana, Toz was already nearing the boundary between the fifth and the sixth level with his void attribute. He wasn't surprised that his practice with void magic ended up pushing him to the brink of breaking through to the next level.
