A 1st level thief outdoes 7 5th levels? Let's have the gory details. Should
be a good story. Mind you. It's pretty likely somebody misplayed, either
allowing the thief to get away with what he couldn't, or not letting the 5th
levels use their full abilities. But in any case, you have already confessed
to being the victim, so satisfy our satistic interests.
Yours for deeper dungeons
