I killed one of these that conned yellow to me at 29 at the far west end of thier habitat and it dropped the Corpsecleaver, a 2H slash sword. I don't remember the stats exactly but my level 28 guildmate loved it. I think it may have been 9.0/5.6 or something like that. +2 two handed, +4 strength or some such stats. Sorry I can't be more precise.
