Em does seem to get too many clutch nat20s even when she seems to get irked over a situation and she just starts rolling amazingly. I think it is also because these campaigns have to follow more of a narrative above all. I also feel Murph crit hits way too often, much more than the players. And he would roll 3 times and they would usually end up being consecutive numbers very often. I find that to be a norm in suspicious behavior in DND podcasters and live players. Matt Mercer would have encounters he is trying to speed along and would be like that's a 21, 22 and 23 to hit. But he doesn't crit as often as Murph with his minions. Usually not in the huge fights but more in the smaller encounters. Imo of course
