I'm not entirely sure what mod was used, but I could probably waste a lot of time with it. It seems like all of the enemies with ranged attacks seem to do the best, just hanging around the perimeter picking people off... unless they were fighting a werewolf. And of course the dragon just flies around for a while, which seems a little unfair. But still a really cool video to watch.
Honestly I'm a little surprised the mudcrab didn't take it
