Largely a mix of bnb/imps/freeti with a bit of velks/kc trash thrown in
The stun / bash hit, bash try and kick/bash try are probabilities, not percentages.
It is assumed all stuns are due to frontal bashes except those caused by sonic bat and stone spider procs as well as heal pots. This means the chance to be stunned by frontal bash is overestimated (kicks from 55+ warrior PCs, stuns from hits to rear, any other kind of proc/spell stun etc have not been discounted).
The table is constructed this way because those are the ways the logs were chunked, not cos i was trying to show difference in the levels.
