This is supposed to be a really rare spawn, I got him on the 5th go this morning and he dropped both versions of the stick. Easy kill for a 75 ranger. Didn't hit me for more than a couple of hundred (2000aa).
Get a healer to sit on pet for heals. Thats the safest way. I duo lvl 70's with a cleric at lvl 68bst. As long as the mob is slowable hehe. I usually proc my avatar and cast fero on self right off the bat in there with pet. Click a celestialX potion and pop my beastial ability. Pretty sure that way pet gets 6-12 procs off and a bunch of taunts. Summoned healer = dead dynamic duo ;). Then I back off after potion dies and dot mob/patch heal pet. On enrage I make sure to dot just prior and then face mob away from pet while not attacking. healer watches my health at this time of course. Duo'd about 6 lvl 70 fableds this way so far. Only wiped once. On the first one of course. Learning curve XD
Most of the lvl 65 fableds hit for around 900-1k...but not sure if he's got any special stuffs...never actually seen him. I've (70 bst) duo'd lvl 70 fableds with shammy...depends on how well off you are i guess ;)
