Its hardest hit is bite at 160 pierce, out of 8 attacks.
Of everything craftable, 
Lightning Strike, 
Frostfire Crossbow and 
Thunderblood Crossbow put the most damage through what it resists.
It always drops 
Morgen Sinew.
Morgen is an Ashlands demon with 1,600 health that lies buried in putrid holes and under ruined fortresses until it breaks out of its disguise, so a fight normally opens with it rising out of the ground at close range. Its bite and its four swipes each deal 160 pierce, its body slam 160 blunt, and its two rolls 50 blunt in a 3 meter circle around wherever it lands. Blunt, slash, pierce and fire are all resisted and lightning is the only listed weakness, but frost, poison and spirit go through unresisted, which is the usual way in. Its attacks also damage other Ashlands creatures, so a morgen pulled into a crowd will thin it. Every kill gives 1 to 2 Morgen Sinew, an 80 percent chance of a 
Morgen Heart and a 5 percent 
Morgen Trophy.
Lightning is the gap in the armor: they are weak to it and little else. The rolls hit everything in a 3 meter circle, so distance beats dodging. Their sinew and hearts feed the best late crafts, which is the only reason anyone opens a Putrid Hole on purpose.
With devcommands enabled, this spawns Morgen in front of you. The third number is the level: 3 spawns a 2-star.
