Hit round 21, got a freezing gnoll slave that has a bow of some kind (firing arrows at me) every second (perhaps faster).
I've also hit a few creatures who had what seemed like obscenely high DS for their level, but that could be just because I'm a KS rogue, but they had DSes (on their bag and stunned from subdue) that was higher than my offensive AS. Even after allowing them to swing. One was an Orc Champion, unfortunately I didn't not the other at the time.
