Killed him today with one group. I boxed 70 enchanter, 70 cleric and 70 ranger, my bf boxed 70 war, 70 wizard and we brought along a guildmate (70 druid).
Warrior had 12k hps 2120 ac, max hit was about 1500.
Was slowable by desolate deeds (partially). Healer mostly DoN merchant gear with a little bit of DoD thrown in.
We tried without patches but was just too much, the patch healer made all the difference.
There were 4 of Fabled Tantor up, dont know if this is a bug or not.
I'd say easily groupable by people with elemental and beyond gear with a patch healer.
Max hit is around 1500-ish. Not entirely difficult to 2 box. He has an AE that's pretty nasty. The best thing to do is to pull him into the tunnel to SG. Have the healer hide behind the hallway into the SG zoneline and the tank pound him down inside the tunnel. He doesn't have that many HPs, so it should be easy with a decent tank.
Min 267, MAX 1025 with mini-defensive. Min 356, Max 1207 w/o defense. Numbers from 12.5k 2.5k ac buffed pally (10% shield)
Dont recall if it was snare/rootable. Resisted all bardslows. May be immune. Summons at 97% and below. Flurries, Rampages and Enrages. Casts <Fabled Mastadon Stomp> (1024dd, -200MR check.
At one point we had 2x fabled Tantor up, seems it can spawn off of any of the mammoths in zone, just kill all of the trash till he pops. Did him twice with seven lvl 70s: pal, 2 sks, wiz, mag, brd and clr. Definitely one-groupable if Time+ .. Mebbe 1.5 groups if Elem-tier etc.
ouch is right...when I saw this thread that said 1300 I figured I could take him, so I went out and gave it a shot
max hit is really a little over 1496 -- thats what he was hitting on my unuber warrior once defensive went down (about 1800 ac, 11k hp buffed, not uber at all, does have max defensive aa's and a couple points of shielding and about 25 avoidance)
his ae has a large range and hits for about 1024, he casts it often
he flurries and summons and has high resistance, I got him slowed with balance of discord after malos and malosinia and then later was able to land turgur's but it took a few tries
I got him down to 61 percent with 4 toons and then we went down (70 war, 70 cleric, 70 shaman, 70 SK) if he didn't have an ae i would have got him but i count on 3 pets w/ panther for dps and the ae owned the pets
just kill mastodon's and he will pop i saw the fabled and the old tantor up at the same time he pathed right by us while we were killing but didnt add. he had a good amount of hp about = to a rss named
