Hmm sure you're checking the right spot? That thing is never killed on Fairy. If it's dead now, I'm sure it won't be camped often. Every time I've checked on it, it's always been up.
It's in that general area, but you have to go around the long way. You can't get to the NM from the shades, but you can drop down from the NM to get to the shades.
Well, from what I read, it's mangle can 1shot non plds. When I was scoping it out, I aggrod it to see how hard it hit and hit my pup for 350ish and critted for 500+ xD
