@Doomer Kurono was already using magic at experiment lab not just barehanded, his raw power was nothing compare with magic that's why he always considering himself as magician not warrior or fighter.
Mad props to you for spotting that. Considering what's to happen as you said, it really makes it painfully fitting that their location just had to be so... apt.
on top of what Torgr said, burning and poisoning resources that the enemy hoped to steal and use is a good way to demoralize them. I'm still hoping he remembers to poison any wells they have before leaving.
@Doomer
Nope, he's still superhuman, he just KOd a giant wolfman with a single punch. But he considers himself to be a magician as that's what he prefers to use. But as the story goes on he'll engage in close combat more and more. It's part of a running gag that he considers himself a magician but everyone thinks he's warrior or berserker. His real class would be something along the lines of a battlemage or spellsword.
