How exactly does one do less than 1? :) Silly bliz.

Comment by gkeebler

It seems to me the best option may be having Fraya assist since she drops sanity wells to keep ur group from not being MCed.

Did this today we had thorim as the keeper and after like 2 hours of whiping we got the achivement!
sanity was not that big of a problem so i think the best keeper to have is the one we had up

Here's what my group did tonite. Overall, this achievement took literally four pulls to do. The only keeper we used was Thorim - he helps to kill the adds in Phase 3, making the fight only a moderately more-difficult version of the normal mode fight.

Group build:

Tanks:
Protection paladin
Feral druid (in dps gear)

Healers:
Disc priest
Resto druid
Resto shaman

DPS:
Blood DK
Unholy DK
Combat rogue
Survival hunter
Shadow priest

Phase 1, we didn't proc any additional clouds to speed up the add spawning. We just let the adds spawn naturally and only had one add (which quickly died) heading into Phase 2. Odds are, if you're trying to do this achievement you already know not to touch the clouds so I won't get into that.

Phase 2, we put a mark over one of the melee dps and over one of the ranged dps - as "focal" points for the raid to group on, as well as focal points for raid dps. The group as a whole stayed fairly tight on top of each other, so that cleanses, heals, brain links, and everything were much easier to manage. The melee group only moved to kill corrupter tentacles so long as they were within cleanse/heal range of the rest of the group - that way if they got brain linked, it wouldn't be hard to negate it. We didn't have either of the tanks "jousting" on the crusher tentacles, but if your group wants to do this, they can.

When it came to the brain phases, we sent the rogue, the two DK's, and the feral druid down. The unholy DK and the feral druid went left (and rotated clockwise) around the brain room, while the blood DK and rogue went right. Killing the adds pretty quickly usually gives you about 35 seconds to reach the brain - and realistally, about 20-25 seconds to dps the brain itself. You already know to kill the brain quickly - we did it in three brain phases. I'd recommend, if you can spare it, to send a hunter down for Aspect of the Pack to speed up the run into the brain room proper.

Phase 3, the entire group clumped together fairly tight on one side of the room. We let the Immortal guardians come to us. The melee killed the guardians while the ranged stayed on Yogg-Saron for the majority of the fight. Be careful with Immortal guardian aggro, though - it can be a tad touchy for the first second or so, and we lost three people to bad Immortal Guardian spawns. We had to use both of our battle rezzes, as well as one ghoul rez, but we still got the kill pretty smoothly.

Just have your ranged dps turn their backs about 1 second before the Gaze cooldown is up, and never have your melee, healers, or tanks face Yogg-Saron. Splash any damage you can on Yogg-Saron as melee dps - this means Consecration, Fan of Knives, Pestilence (plus diseases) and the like.

Overall, this isn't nearly as difficult as Firefighter is. Good luck everyone.

Edit: apparently, some jerk came running through here and downranked every comment made on this achievement so far. Even the ones with pertinent and useful information.

Note that you do not lose Sanity below 30 except to Lunatic Gaze, so even very bad RNG will not affect you beyond a certain point if you are careful. If everyone is turning around a second or two before Lunatic Gaze, Yogg is pretty easymode.

Comment by Rafikiooha

Is there a good way for a feral druid to position oneself so that swipe hits Yogg without risking sanity loss?

My guild has this fight down pretty well and are slowly working towards 1 light, but with sanity being a bigger deal in 1 keeper will I have to be strictly on add control?

Comment by shiltonnk

we did this a few days ago, and well its not that hard but not that easy
raid setup
- Dk blood tank
- Feral Druid (half tank)
- 2 Elemental Shamys
- Fire mage
- Pew-Pewkin
- Dk Unholy
- Disc Priest
- Holy paladin
- Resto Druid

we did use thorim guardian for the fight to help manage the fase 3 adds
In fase 1 we let the dk tank stand in the middle avoiding clouds and taunting the guardians as they spawn, the rest of the raid spread in a semi circle avoiding cluods and dpsing the guardians as they spowned, our dk tank said that he would be very very happy if the had 2p bonus from t9, hell he's right
as fase 2 started we tryed to nuke crushers very fast, we can get some time to clean the room from the anoying corruptors, when somebody gets caught by a constrictor we had mele dps and a designated caster to help him out, when portals fases pop up we make sure to send the portal team with abolish spells up, so if they get caught by something hopping not a constrictor or a apathy debuf, they will get cleansed in the way down, our portal team was the feral druid both dks and a elemental shamy, we send down the tank because we wanted to save him as much as sanity as possible, and the shamy for heroism on the brain which almost let them blow 50% of the brain HP in one portal fase.
it is important to manage malady debuff in the raid at all times it cant spread or it will become a sanity mayor problem, this is solved by a good comunication over ventrilo
we as i think where kind of luky in blowing the brain in two fases, we had to use a 3rd to clean the corruptors before fase3
in fase 3 we let the dk tank pick every add as they spowned and the mele dps burned themdown, the feral druid helped taunting any out of control add if necesary, this is most a phase of control than dps, we had 4 and a half minutes to do it, so dont panic save sanity and only dps while the chaneling is on cd, dont risk any loss of sanity and he is dead ;)

nice fight took almost all of our concentration to do the last fase
have fun ;3

Edit: Wow, is it really that long time ago? I can't even comprehend how much have changed since then. According to wowhead, it seems that you can still complete Glory of the Ulduar Raider Glory of the Ulduar Raider (10 player), but I guess you can roflstomp through the achivements with +2 level 90'ties.

From whats it worth, here is how we did it.

Raid composition:
Retribution paladin
Affliction warlock
Shadow priest
Protection paladin
Feral druid as dps/OT
2 x restoration druids
Restoration/Elemental shaman
2 x rogues

Thorim was our keeper as we believed his ability was key to survive phase 3 (Titanic Storm)
Im not going into details as I assume people know what this fight is about when engaging this archievement.

The first ~10 wipes we realized a few things:
Phase 1
Our 2 trees where capable of healing everything, so our shaman went elemental, which made the encounter more smooth and allowed us to spawn an extra add like we are used to in the beginning.

Phase 2
Yogg + 1 keeper (Thorim) is not as forgiving as 4 keepers since you can't replenish sanity, run slower, do less damage to adds/brain/Yogg and you recieve more damage - RNG plays a big part of your sanity loss.
Although rare, out of numerous tries some of our players got Psychosis 2- 3 times in a row.

As much as possible, we moved in a group and kept 2-3 yards between raid members, this makes it easier if people are Brainlinked, Deathcoiled, get curses etc.
Remember, if someone is Deathcoiled, get away from him because it chains to people nearby. If you use Deadly Boss Mod the person gets a skull above head.
Our protection paladins job was to locate the crusher tentacle every time new one spawned, we didn't find it nessecary to interrupt it. Ranged killed it while whole raid followed him around. Melee killed the constrictors and corruptors in between, constrictors being first priority since they grab people.

Our brain team was retribution paladin, feral druid and the 2 rouges and each of us had assigned our own portal, this is imperative because if you take each others portals, you might not have time to reach another before it despawns. You should aim for atleast 3 times in brain to beat enrage timer so every member of the brain team have to enter.
Personally I used the entrance gate to locate my assigned portal for easy access.
Feral + pally to the left in room and rogues to the right which worked fine for us.

Important! Do not enter brain if you have Curse of Doom unless you have a decurse capable class with you like our feral druid. If you dont, then either wait for a dispell or bubble + cloak of shadows out of it before you enter. Our 2 trees outside couldn't dispell us inside brain and it will be instant death.

Phase 3
We all gathered at our protection paladin while he grabbed adds as they came for us. Shadowpriest and Warlock kept their backs to Yogg all the time and dotted him up while melee were hammering the adds.
I'm the retribution paladin and I realised quickly that our dps on adds was great so I used most of the time judgeingYogg, doing Consecration and Divine Storm to help damage Yogg, this worked nicely since all can damage from behind.

So how did it go and tips
Untill we perfected the above we used 3 hours before the actual kill, the hardest part was getting phase 2 under control and people grabbing each others portals in the chaos.
It worked with 4 dps as brainteam, but maybe 3 dps and 1 healer would do the same trick - its up to you to find out in your own raid.

From a retribution paladin point of view, I did my best to dps but also to support my raid:
Extra adds is really not a problem, but doing this achievement it can be. So we kept melee from adds and only let our ranged deal with the adds, but:
- while we were dodging clouds in phase 1, I judged Judgement of Light for extra healing support
- I used Exorsism and Hammer of Wrath whenever I could on adds in phase 1.
- You can Divine Shield out of Constrictor Tentacle (mages can Ice Block)
- Dont hesitate to use Divine Shield + Divine Sacrifice if you are stuck in a Constrictor Tentacle and noone is near to help you (this never happends ofcourse :D ) or you see raid taking heavy damage.
- Lay on Hands ; use it! whether its on yourself or fellow raider.

GL to all.

We attempted this finally and it didn't seem too bad.

Group Comp - 1 tank, 2 heals, 7 dps.

Phase 1 is pretty simple, don't stand in the clouds and kill the adds. Having someone constantly interupting dark volley will save you alot of wipes as 1 person getting 2 of Sara's debuff + dark volley can kill them, we made our enhance shammy do it at range with wind shear.

Note - you cannot Lose any sanity in phase 1.

Phase 2 - this is what will make or break your attempt. Your group needs to stay together to make brain links and constrictor tentacles easier to deal with. Also assign portals for each of your portal people to take so other don't take the wrong portal and leave someone stranded. Efficiency in the brain room is a must. The faster the brain room is cleared the faster the tentacle and Sara will be stunned and the less your outside group will have to deal with and the more Sanity you will have for phase 3.

Note - this is where you'll take the most sanity loss, efficiency in phase 2 is key to this encounter.

Phase 3 - Tank picks up the guardians as soon as they spawn, the tank must be on his game as the first one spawn right as P3 starts and if hes not paying attention it will kill someone. Assign people to kill the guardians and if you kept Thorim as your keeper he will kill them when they get low. Also Yogg will do his Lunatic Gaze, you must pre-emptivly turn away from the gaze.

Note - the only way to lose Sanity in phase 3 is by looking at Lunatic Gaze it is a must to turn away from it before he casts it because even looking at it for 1 second each time he casts it will slowly drain your sanity and you will probably cause your group to wipe.

One last thing - His enrage timer is 15 minutes, so take your time and do things right.
For example - on one attempt a tentacle spawned on the opposite side of Yogg to where we were in P2, our mage decided to blink ahead of the group and start killing it and guess what happened. He got brain linked to our boomkin who was still with the group on the otherside of the room and then the boomkin got grabbed by the tentacle, so this mage single handedly caused a wipe for us on that attempt just by blinking ahead to kill the tentacle.

Good luck with your kills.
