I see a lot of prior comments bashing the MC as being an idiot. I mean the MC is a young kid and not at all savvy (I mean, my god, look at him try to lie to Ms. Hitsugaya, the guild rep). Getting ripped off by an older (and far more experienced) merchant is going to happen. And he's never wielded weapons or armor in the dungeon before, so how is he supposed to know better? The equipment worked in some circumstances (shield bashing the goblin, reach attacks with the rod against the gobs and skellies) and not in others. It basically seems like people learn through experience rather than information from a guild or other organization. As for his interactions with Sylphy--he's treating her as a human girl and not as a living weapon. I honestly would think less of him if he depended on her all the time. I like the idea that he's trying to level so that he can fight by her side rather than just standing behind her.
