I mean, it doesn't appear to really make a difference anyway: skaven armor has never really been that effective anyway, and this way we get to see the goods, but like, at the very least, they should keep something on as some sort of UV protection....

... wait, why the hell am I complaining..? That's a RAT OGRESS. Them tiddies are the size of my actual torso, bring it on.
