Hundred Club doesn't check pets for the achievement. I've completed both 10 and 25 man version with motw buffed on myself and my pet.

Note too that a mage with the magic absorption talent (low arcane) and MotW will have more than 100 frost resistance, so if you have any fire, frost, or arcane mages who have that talent (frostfire mages won't have it) make sure they click off mark before you engage.

For those still having the Razuvious problem.

It's caused by tremor totem, It instantly breaks the MC, and for those of us who put all the priests in the shamans group for 1% hit and have pro shamans like me who just drop tremor because we are so used to it because of the old t6 2 piece may have big problems.

My Group is new to Naxx, How should the progression go in Naxx (What order should the wings be run in?)

Whatever order you feel like, the difficulty and "progression" is nothing like it used to be. The only steps up in difficulty are Sapphiron and Kel'Thuzad. Patchwerk is nothing close to a gear check anymore, except possibly the hateful tanks in 25man.

It can still be said for a group entirely new to raiding the challenge at Thaddius (executing the strat) and 4H is probably going to be a bit tough. Other fights like Gothik test your communication as much as gear or strategy and can be hard for new guilds that have not played with each other much.

Overall there is no "required" order of bosses or wings as there was in the 60 days, so just try out the wings that sound interesting and go from there.

One of your warlocks has really low average of frost damage taken compared to the rest. He wasn't using a felhound was he? It's slightly hard to tell from the log, since it doesn't show his pet doing anything other than taking damage and some healing.

He's sitting at an average of 975 per tick, while the others are taking between 1250-1800 a tick. One of your priests was about 1k a tick as well. Yeah, see what Dolor and Starrshine were doing compared to everyone else.

Beg to differ - we tried using out-of-the-box tanks on Patch-10 and got raped. The next week we'd pounded a few more heroics and did fine, though, so there's not much in it.

The route we took for both Naxx-10 and Naxx-25 was Spider, Plague, Military, Construct, but if you have the nous to handle unusual execution fights you could go straight into Military without batting an eye.

The felhunter Master Demonologist buff no longer grants resistances. It gives reduced magic damage taken.

You are right, after some probing, it seems that Dolor inadverdently put on some resist gear. Human error.

From easy to hard assuming your guild is relatively new to raiding and not into much theorycraft I'd say go like this:

Noth
Anub
Faerlina
Maexxna
Heigan
Loatheb
Patchwerk
Grobullus
Razuvious
Gothik
Gluth
Four Horsemen
Thaddius

That's how I would rate them in order of "difficulty" with Thaddius being only rated last because the insane UI lag you'll experience there will take a hefty toll on your DPS on a fight that's fairly well-tuned.

Razuvious is more annoying than anything else unless you have two good priests that can communicate the MC's and taunts well. Patchwerk isn't hard per se, but the hateful strike tanks are going to take more damage than you're used to in any form of heroic or even most TBC encounters and will probably require some partial Naxx gearing for your offtanks.

We've had times during our early kills when both priests were renewing their MCs at the same time. Razuvious moves very fast across the room. Or at least it seems deadly fast when he's one shooting people. You could try having your tanks taunting Razuvious during refresh time and burn a CD. You can sort out a sequence of CD to use between tanks and healers. (See any 3 drake sartharion strategy for inspiration of CDs they use to survive breaths).

Also, MC range is only 20 yard, and the further the mob is the easier it is to break. You could also switch to an alt priest for the fight? The priest don't need any gear to MC an understudy.

The bone-shield spellstealing technique was removed in a hotfix. I'm not sure what it is they changed exactly, but it's no longer possible. (The reason for this is most likely the fact that a mage soloed most of the wing with an arcane talent that gives you a stacking spellpower buff when you fully absorb damage.) As far as i know, the hunter alternative still works.

Your hunters can use Distracting Shot to taunt Razuvious for 6 seconds, after which he will go back to the #1 on threat. There's a video where 3 hunters rotate Distracting Shots to keep Razuvious on them for the entire fight. If you have a priest, you can conjure up a hybrid strategy where you use 2 (maybe 1 is enough) hunters to Distracting Shot Razuvious when the priest breaks MC. They then occupy the boss for a short amount of time while the priest reacquires his target.

You'll probably have to figure out some positioning that allows the hunter(s) to kite easily while reducing the time the priest needs to move the understudy back to Razuvious after re-MCing. The chance of success will strongly depend on the quality of your hunters and priest.

One priest Razuvious just wouldn't work.

With 2 Understudies they taunt and resume the threat of the other, therefore staying ahead of DPS threat (like normal tanks do). With 1 Understudy, when the priest loses it, your top DPS takes aggro. You MC a new Understudy and taunt. You now have threat identical to the top DPS. 9 times out of 10 DPS will pull aggro as they are generating threat faster than the Understudy. The Understudy's attack generates a lot of threat, but has a lengthy cooldown - unless they build up a lead over time it's easy to surpass within one cooldown. Even perfect MC rotations can have excellent DPS chasing Understudy threat.

I'm sure anyone who has had difficulty where one broke early and the other Understudy wasn't yet on the threat list can confirm this. You lose 2-3 DPS every time it occurs. If you know it will occur every single time an MC drops... you're not in a good way.

I'd suggest your guild power-level someone's priest alt from 70-80 (surely someone has one) and have them swap just for that fight, or find a priest in a small 10man guild and get them to join you just for Razuvious every week.

Sudden thought - other alternative is right after an unbalancing strike have a tank taunt off Understudy, drop MC, start new MC, taunt off tank before it can be unbalancing-gibbed. You would preserve threat, but your risky points would be standard tank phases - the tank could possibly die before healers realize (s)he is tanking, swap target, and casts complete.

You know the Understudies have a 20sec duration taunt? Unless I've missed something, the debuff stays on Razuvious for 20 full seconds.

Will a shieldwalled tank survive an unbalancing strike?

If so, you can do the same thing that's being used on Sarth 3D where you blow panic-button cooldowns to survive one hit before the MC'd understudy taunts it back. Two of those cooldowns come from priests though, so that probably makes it a bit of a redundant strategy :-)

If a DK with boneshield up can survive a hit you're probably in good shape as the cooldown is relatively low and they have two more options as well.

Just last week our 2nd MC priest was having trouble making MC last more than about a second. The other priests didn't pick up any adds. I basically solo tanked it after the first rotation. We lost 1-3 players per recast of MC, and probably made it through sheer force of DPS. My guess was she was recasting MC while still channeling the previous, but I didn't confirm it with her (just wanted to move on). I also checked with the shaman and none of them had tremor totem down.

Anyway, my point was that if you have good enough DPS, you can probably just brute force it with 1 priest and just lose some people each rotation.

The most common cause of fast, 0-1 second breaks, is lag + priests moving before the MC really takes hold of the mob. If your server is notoriously laggy on raid nights, then just have them make extra sure their MC has completely taken before moving into position.

A very effective sollution we found was having a army of the dead rotation on each MC reapplication. Having 3 or more Deathknights helps a lot here.

The bone shield buff is no longer stealable, however it can still be removed via Purge/Dispel/Tranq Shot etc.

Question for everyone:
Last night my 25-man raid tried to do Momma Said Knock You Out. We killed off the two Followers, then pre-emptively sacrificed each Worshipper, keeping her silenced for the duration of the fight. At no point did she do her frenzy yell, or gain the frenzy buff. She was definitely silenced each time, as we sacrificed every 28 seconds or so.

However, we didn't get the achievement.

The only unusual thing I noticed was that BigWigs flashed a "Frenzied!!!" warning early on in the fight, but this was not accompanied by a frenzy buff on the boss or her emote yell.

Has anyone else encountered similar weirdness with this achievement?

Also, just a warning to people not to kill Noth the Plaguebringer with dots while he's on the balcony during the adds phase. We have managed to do it two weeks in a row and are still waiting on our loot from GM tickets

You can't kill any worshipers, EVER, if you want the achievement.

edit: We decided to do it in 10 man so we had our ot wear dps gear and just burned her while the adds all just kinda nuked whoever and ended up having her frenzy at ~20%, lost 3 people including the mt and got the achievement.

But in the end it's not something that should ever even happen at all? I've never been present for that occurance. Treating the symptom when you can just remove the problem is kind of foolish. Unnecessary complication.
