Just yesterday I noticed something that kinda winded me up at first and then I started thinking about it and now I need your help. When stuff is in an autocrit situation (like being held) it seems that the crit multiplier taken for it is the one without my FBIII enhancements, which in my case means x3. When I saw those low crits I first checked that I am indeed raged and in DF, and I was. So no error there. Then I figured the thing is bugged with autocrits. But I think there's more to that, and need your confirmation on this.
Could it be that since the autocrit hits aren't a roll of 19-20 that they only get the base multiplier, and would get the full x6 if I was to roll a 19-20 ? I don't remember seeing the high crits on an autocrit but it might be I just didn't have time to roll one.
Sorry if this has been mentioned somewhere, as I haven't noticed it in my readings.
