Man StormlyStonehand, we seem to have similar schedules.
I see this effect most on "The Big One"than on any other bomb in the game too bad it takes a large pile of stuff to make em,I think it has someting to do with the level of the mob vs the level of the explosive,becaus I Get them Dazed all the time when I am helping out folks lower than me and they get hit by a explosive, but maybe some of that is a effect when they loose half their health ?
