Can be fought by 3 main options:
Having at least 3 decently strong creatures so while it picks up 2 the third one will fight.
Have a mount that it can't pick up fight against it.
Shoot at it metal arrows to counter it's damage resistance from most projectiles.
Do these things play dead? I can see one directly on the floor in front of me and it's not moving. I have to go past it to get to my base... I moved in to investigate and it was dead but my question is, what killed it? It wasn't low level and they're not weak.. Now I'm scared :S
