I'm raiding shadow and pvping on my hunter. Finding it to be a bit more beneficial to the raid. Guess I should change my sig eh? But anyways, in case anyone else is also interested, with VE up I am able to eat a full duration of the blue beam, so a warlock and I just alternate. This seems to help the mage survivability quite a bit, not to mention put my dps thru the roof. =)

About two weeks ago we played around with Netherspite to see what the fight looks like. Nobody was really serious about attempts. We had cleared the Prince and people needed to log. Had to have a look at the color beams and let people get an idea what we're in for though. Tonight was our first evening of attempts and a kill.

Some notes re: the blue beam, since I was part of that rotation. We were using,

Warlock (me)
Mage
Shaman (he's Elemental, but primarily healing.. only DPS while he has the blue beam)
..and our DPS Warrior, the OT for tonight in good tanking gear and a Gorehowl

Both the Mage and I let it stack to ~ 20-25 or so, and then we hand off to either the Shaman or Warrior. Depending on if he was part of the red beam rotation at the time. We basically only used them as "buffers" to give healers a little more breathing room. I'd say the Mage and I were in for ~ 40 seconds each. Near the end, it worked out perfectly that our Warrior had the blue beam for a good 30 seconds in Execute range with Heroism up.

All in all, a really fun and rewarding fight.

The bug I have noticed on Netherspite a few times is that he will aggro the next red beam guy a split second before that guy has the red beam buff, and if its not a real tank, this will result in a splatter.

are you serious? this happens without fail? seems like a really easy way to trivialize the only part of the fight that could give anyone any trouble.

We tried having myself (Shadow Priest) in the green beam, worked wonders, I was doing good DPS and healing everyone in my group with VE, no aggro to worry about either. Also Major Dreamless Sleep Pots go down a treat during the 'run away' phase.

We also moved his position away from the doorway to give us more time for each pickup phase. Great fight, lots of variations and methods of taking him down.

Was just about to dig up this thread, as we had some experience on Netherspite last night that was sort of interesting. Not that we haven't been killing him weekly for quite some time now, but we had some new people along yesterday, so we changed our regular strat a bit to make it simpler. Basically, we did the fight with only 4 people ever taking beams.

Me and another warlock alternated the blue beam (1 of us holding it an entire non-banish phase), healing ourselves easily with Drain Life. Then we had two warriors taking the red and green beams, one full non-banish phase each. One of our new guys insisted you could tank him with one tank the entire phase by having the tank move in and out of the red beam to let Netherspite gain around half the ticks of the red debuff. Worked flawlessly.

Not saying this is optimal, the warrior in the green gains nothing and takes more damage than if you alternate it etc, but we still got him down in less than four and a half min, which is acceptable for us. And though this won't apply to most readers of this forum I guess, this lets you tell half the raid "stand here, dps/heal, watch out for void zones, run out when told", which vastly simplifies bringing in new people with little raid experience.

Also, we had no idea you could do it so easily with just two tanks, so I thought I'd share that for those who like us often have strange setups. (e.g. a warrior and a druid and then just cloth makes our regular strat hard to execute for instance (yes, we've had raids like that)). Apologies if that's been mentioned earlier.

It takes 20 seconds after leaving a beam before the debuff fades, and when the debuff fades is the moment you get exhaustion.

Ah ha, i always assumed it was instant. Would the tank moving in and out of the red beam like this retain the agro buff? Because that would reduce dps i would imagine if you had to keep to conventional agro rules while the tank was out of the red beam.

You keep the extra aggro as well, I don't generate half as much threat on Netherspite as I usually do, but our buffed up blue beam DPSers can still go all out despite this.

With some practice your tanks should average about 20 to 25 stacks with never more than 5 stacks on Netherspite during one beam phase.

As chicken said it takes 20 seconds before the debuff kicks in. Running in again and getting a new beam stack resets the timer. The Netherspite dance is basically standing in the beam for 1 second, then moving out for 3 seconds. It prevents the stack on both Netherspite and the tank growing too big.

Edit: Getting and leaving the beam pretty much gives you infinite threat until someone else takes the beam.

We just use 4 tanks (usually 2 warriors, a paladin and a shaman) usually a warrior + other, for each phase, i guess you just use what your used to.
