Mobats are pretty tough for an apparent lowbie spawn(they must be lowbie, for the XP they give me at level 7). I suggest toning them down, since if I can't manage fully buffed, bearformed, with my bear companion, I doubt even a party of lowbies could manage. Adriana's will save is pretty high for her level, so she didn't have to worry much about the howls, but imagine.. levels 4-5 have about.. 7 will? maybe a little bit more. They'd get stunned like, every time they howl(and they can get pretty spammy) and just die. There's nothing wrong with a challenging dungeon, but it's kinda boring when you just get slaughtered.
Maybe they should be toned down a bit, or be worth more xp if they're going to stay this tough.
