'Oh, look at that, it worked!'
Cedric blinked as he saw what happened to Anton. To be fair, he wasn't sure that it would end up like this. He was just trying something out and it succeeded...somehow, at the expense of Anton's well-being but that's to be expected, after all this is a fight.
[Notice! Skill: 『Dispel』 learned.]
Yes, Cedric tried using Dispel through clapping and it worked. Typically, he needs a medium like a wand, orb, or a staff to cast a spell. Additionally, one needs to chant an aria to do so. Of course, there are ways to bypass those requirements; such as having perfect control over mana, Ki in Cedric's case, or having a complete understanding of the spell.
『Dispel』 is Magic and usually needs mana to cast. However, there are ways to work around it, otherwise, how could Cedric cast it when he doesn't even have an ounce of mana in his body?
