Killed him twice this year (2014), and was my 1st time ever able to get him to spawn, last year normal version spawned for some reason. Wasn't sure what to expect so I brought all 6 of my chars.
Group consisted of my army:
Gold Account - 94 Barb BST & Wolfie - 8k aa's - T5 Geared / 85k hp's / 7k ac (I will retire her soon, higher levels are soo boring).
Box's include:
Silver - 95 Mage + air pet
Silver - 95 Shaman + spirit wolf
Silver - 95 Chanty + animated warrior
Silver - 95 Cleric
Silver - 95 Druid
When I initially spawned him he casted some pb ae and drained all mana off my box's, so I zoned out / in and placed them in the far corner. Fight lasted less then 20mins. On my 2nd go around I knew what to do, where to place boxes, and fight lasted maybe 15mins. Both times he dropped Fist and what ever else (I was only after fist and didn't pay attention to other drops). He is really easy, just a ton of hp's, and I only used shaman for heals when both sets paragon & warders gift were used (cleric & druid was there for b/u. I didn't even pull their screens up once I parked them in the corner). I did notice "finishing blow" finalized the final 7% health he had. Weird because I thought fabled's had to be killed every % step of the way *shrug*. Anyways, fun fight & my new baby bst (Wood Elf Bst & Trent this time) will have a nice weapon when she hits 75. Then we all moved to PoV and killed that fabled dragon (had to pet pull him because floor was locked) for the other nice 1hb weapon to use with these Fist for my baby bst!! :) :) *Hugz* =)
