About that warrior guy, I guess he has some personal reason. Maybe bad parting with the last healer of their party? Or jealousy about one of the beautiful women in their group?
So many angry people in this comment section. A run's success depends on the party not breaking up due to stupid arguments. Way more than on the participants' individual abilities.
@Mnuchinboo - the way I see it, bikini armor is mostly made of magic. It needs to have bits of metal for magical symbolism, but is light and easy to move in. It's cheaper than armor made of matter, because it's production is subsidized by perverts.
It can be worn with actual clothes, and women who don't, like it this way. Maybe they're really desperate to attract men. Or they have an awesome body and like to show it off. Or they want to make sure no succubus can tempt her party's men.
@greyhud90 - he was like that from the start - a quite nice and polite person in social situation, a terror on the battlefield.
