I killed high shaman 7 times and got 1 odd cold iron neck. since he spawns only 1 time every hour it took a while. I got 7 to drop in 1 hour in stonebrunt killing all the trash kobolds around warrens entrance. If you need these, you know where to go.
oh yeah ( edited) they seem to drop off both greater and lesser kobold shaman in stonebrunt. so far no other mob dropped it for me.
another edit - got one off a kobald wanderer just now. I keep on farmin'
another edit. i finally got one off a kobold spiritslaver (in stonebrunt of course)
