[Quick write-up so it's here, I might expand on it later.]
We had the second game a few days ago. We began with them breaking camp and returning to the road after a brief discussion on if they should do that or circumvent it and cut through the woods to the Pit. They decided that they'd already slaughtered a dozen or so margr (one with a hunting horn) so they figured if they hadn't been attacked in their sleep they'd be fine for now. As they entered the woods Wemm and Mag spotted a couple of scouts. When they did Mag started shouting at them and they ran much to the chagrin of the others. When they knew they'd been spotted they ran off, presumably to warn the rest.
The group was then ambushed at the edge of the woods by a group of four margr, two regular hunters and a pair of mutants. They dealt with theses quickly, though one of the mutants had 4 mental armor so when Xavier hit it with a mental Onslaught it just shrugged it off and stabbed Wemm which made them pause for a minute. The noise of combat also drew the attention of the chieftain and his remaining lieutenant (both mutants as well) and the five remaining warriors at their encampment. As they were discussing what to do next a volley of 8 inch long, barbed quills flew by Vash's head. Which a yelp from him and a bellow from the chieftain combat ensued. Charging at the group were the margr chief (a brute standing head and shoulders above the rest of it's kin, so about 9' tall, covered in heavy armor and bristling with the above mentioned quills), his lieutenant (who was covered in armadillo plates instead of fur), and the five normal warriors. In a turn of events I hadn't forseen Mag threw a cypher which randomly rearranged the molecules of whatever it caught within it's blast radius. The chief and lieutenant were too fast but the five normals were alternately liquefied, vitrified, turned inside out, turned into a pile of maggots and I think there was just physically shredded as well; all randomly and not all at once. After this, decidedly not pretty, turn of events the two mutants attacked. Wemm was forced to pick up a staff (actually a spear he broke the head off of), his first weapon of the game even! It was a little desperate for a minute but they managed to kill those as well.
In the aftermath of the fight Vash, with the help of Mag and Xavier, dissected the chieftain to find a cypher had grown inside it's brain. Presumably a side effect of whatever had caused it to mutate the cypher could be taken as a pill to increase intelligence.
