Regarding the "buggy" laser barrage in phase 4 of Mimiron - it's actually not as buggy as it seems, it's just odd mechanics. As noted a few pages back, the laser turret spins in relation to the front of the bottom (tank) part and not in relation to the ground. That means that if you don't turn the bottom part during the barrage it will do the regular ~180 degree clockwise barrage. On our first few goes at phase 4, the tank would run to the other side of the laser turret to avoid it himself, turning the tank in the process. That also caused the turret to swing around to maintain it's relative facing with the bottom part. Since it fires so fast, it would kill a few people during that turn, usually the tank included.

Now, once your tank is dead, you're screwed, because the bottom part will move towards whomever is highest on aggro now, which probably involves a turn, causing the laser turret to spin around again to go back to its previous relative facing, likely killing a few more people in the process. This behaviour looks as if it's a random bug that wipes your raid every few tries, but it actually isn't.

Funny enough, you can use the mechanic to your advantage by turning the bottom part counter clockwise at the same speed the lasers move clockwise. Since they will maintain their relative facing to the bottom part they will not move at all, making avoiding it fairly trivial.

We had a night of attemps on him on thursday and had this happen as well. We went back sunday to kill him and have not seen this happening again. If anything, the hotfix has fixed it for us, but given your experiences I'd say it's safe to assume it's still bugged.

That said, you don't really need all 8 clouds to get the job done, so missing 1 because it's bugging out isn't a huge issue.

Do not dot the vapours. If they die to a dot tick, the resulting slime will not do anything.

I believe the magic number is 4 in 10 man based on our clear last week.

Besides Ignis (supposedly), are there any other boss in Ulduar not affected by parry haste?

 

Kirth

Did some testing of what mana regen was and was not working on vezek last night.
Worked:
Rapture
Judgment of the wise
Seal of Blood/Martyr
Lifebloom returns
Aspect of the viper
Hymn of Hope
Water Shield
Improve Stormstrike

Not working:
Replenishment
Innervate
Mana Gems
Shadow Fiend
Mana Tide

Seems anything talent related that is independent from spirit regen will still work.

We're having a hell of a time with phase 1 of mimiron(10 man), it could just be our tank types (paladin and druid) but even with two healers focusing on the tank (usually a disco priest and resto druid, the shaman is on raid heals) the plasma blast is just wrecking them, and we've seen a few cases where he's casting plasma while charging for the lightning nova. The tank winds up running away and there's no chance to dodge the plasma while that happens and they faceplant. It seems like who plasma blast targets is a bit buggy at times too. If the tanks switch agro on the pull, he'll still at times blast the first tank even tho he's been on the OT for 10 seconds solid.

Once we get past phase 1, phases 2 and 3 aren't really a problem.

It seems like phase 1 is almost hand designed for a DK/Warrior combo, unfortunately we have neither of those. Both tanks are very well geared (all 213/226 level stuff) and we've had no tanking issues prior to this encounter. Anyone have any thoughts or have you done it with a similar setup? (druid/pally tanks)

Thanks.

To add to this list, we found that Imp Stormstrike does work, and Mana Tide does not.

We successfully do this with a pally MT. First Plasma Blast he uses his shield wall (forgot the corresponding name for pallys), second plasma blast I use Hand of Sacrifice + Beacon on him an just heal myself. If we occasionally get a third blast I use Fire Resistance Aura + Aura Mastery + Avenging Wrath. Using this we get through phase 1 reliably.

 

cecukemon

We're doing it with a warrior / druid tank. The warrior takes the first plasma blast with shield wall, I run in and taunt after the lightning nova, eat the second blast with barkskin and the third with survival instincts / glyphed frenzied regen.

 

Kirth

Pain suppression on the first beam when the laser cooldown timer is at about 1-2 seconds, I also like to time weakened soul so I can pop a fresh shield on the tank when the beam is about to cast as well, additionally ignore anyone who eats a napalm blast during the laser except maybe a shield or Prayer of mending. The second beam is handled by tank cooldowns but again try to line up a fresh shield and be prepared to focus solely on the tank. If you get a third beam just have your OT taunt and blow his cooldowns as well. I haven't seen the beam cast during a shock blast, I have seen it come almost right after however. After a blast on phase one our OT, who moves in the opposite direction of the main tank, usually taunts to move the tank back into position in the middle and it hardly moves out of the center.

With proper dps you should only need 3 tank CDs. We used a warrior/pally tank combo. I (warrior) started off. I shield walled the first plasma blast, and used LS for the second one. Then the pally tank taunted off me and used his shield wall thing for the 3rd one. If you have enough dps you might only get two even, for us it seemed he did the 3rd one right as he was dying. If really need be, you could heal through it (assuming you're running 3 healers). I forgot to SW on one of our early attempts and our healers kept me alive through it.

We run druid / pally tank, I'm the druid. We were working on this last night. The best think we did was have a Hand of Sacrifice rotation on me. The pally tank would go first, Hand of Sac then Divine Shield. Our holy paladin would use the second Hand of Sac on me. I would use barkskin on the first plasma, and then SI / Frenzied Regen on the second. We would usually be able to push him into stage 2 in two plasma blasts.

From your setup you don't have a holy paladin for the second Hand of Sac, so have your paladin tank Hand of Sac the first plasma blast and divine sac the second. Hand of Sac caps at 100% of the paladin's health and Divine Sac caps at 150%. I would have the pally tank use Hand of Sac and then heal himself to stay alive. Use the Divine Sac and Divine shield combo to prevent his death from the 150% damage.

Edit: If you get a third, pain suppression works for that.

When the plasma blast happens, all three healers need to focus the tank. The only other raid damage is the Napalm Shells and that's lower priority. Be aware that the first plasma blast happens around 10 seconds into the fight, so make sure the tank gets fully hotted, save the PW:shield and swiftmend and just be ready for it. Its a whole mess of damage, but it can be done.

The 10-man version is definitely healable, annoying as it is to actually heal it. The 25-man should have plenty of external cooldowns to use.

 

Szynszyla

We have had different tanks, different healer setup at mimiron, while having sometimes trouble to heal 10man plasma blast it was always becouse ppl didnt line up their direct heals and didn't spam them during.

Healers must be encouraged to not cast any hots , shields during plasma, if they do, the lost GCD is likely to mean a dead tank. Full prehot before plasma or during its cast, shield and than straight forward spam with direct heals.
It sounds like your healers are not doing their job, likely they don't, since many still likely didn't change their playstyle/adjust after months of naxxramas.
Just to make sure, i hope you used 3 healers in this encounter. We tried 2 healer setup, disc + Rdruid or Hpal/Rdruid and a DK tank with 46k HP and still he would get gibbed even if we did our job perfectly.

 

Dralmoo

The fight is totally doable with 2 healers on 10-man if the tank uses cooldowns (and what else would he use them for, anyhow).

 

raiod

We use 2 healers and warrior/druid tanks on Mimiron 10 (non hard).
For the first plasma blast i shield wall and then the druid taunts and uses barkskin/laststand for the second,
after that we are in phase 2 if no dps got himself killed.

 

nooble

For the Pallies out there:

Doesn't work
Illumination (talent)
Lay on Hands
Judgement of Wisdom
Seal of Wisdom
Divine Plea

Does work
Blessing of Sanctuary (talent)

It would be nice if Blizzard was a bit more consistent with Aura of Despair as their tooltip lists only a few abilities.

 

Xunwael

If you say so, I guess. Sure isn't exclusive to dot ticks, though, since our mage killed one tonight with arcane barrage and it did squat.

We just cleared him with 3 ranged dps and he wasn't targeting the melee so it's lower than 4. Sure gets annoying with only 3, though - I got the mark of the faceless 7 times in a row and was allowed to entretain myself in a corner somewhere for large parts of the fight.

My healers think death grip stops them from working, so I don't do it anymore, but they still report vapors bugging out on occasion. I expect the bug is in reality unrelated to how they are killed.

 

nooble

We had a DK on cloud duty and we had one spawn and fail to give regen.

 

fr0d0b0ls0n

With 10-man gear is hardly healable (we maybe healed 1/5 of the plasmas w/o CDs). Is mandatory to rotate cooldowns: we use Pala's Shield Wall and Divine Guardian and kill him usually seconds before the 3rd plasma.

I am pretty sure that this is not the case. If the laser barrage starts out facing the tank, and he moved to avoid it, then the laser turret would also move and aim towards the tank. This would mean that if the laser barrage happens to be facing the 180 degrees that the tank is on, then the raid wipes because the tank dies.

Have you done this on 25man? In our 10man the laser turret section did seem attached to the bottom, and the laser barrage would never aim towards the tank. On 25man, however, it just went crazy sometimes. We tried 2 tanks taunting, focusing on having zero deaths during spinup, perfect strafe-circling, cooldowns to stay in during Shock Blast...but in the end it just felt like we got lucky with not having him bug out.

 

Tojara

Found the easiest way to deal with the laser barrage in phase 4 is to just have a second tank (or dps paladin/warrior with a shield) be directly behind your MT and taunt when the boss is spinning up. They only have to do this if the boss is going to spin on top of your MT (he definitely doesn't spin 180 degrees, more like 120~). Once taunted the MT runs into a safe position and taunts it back quickly.

Using this method your MT doesn't have to risk repositioning him. Although it is very possible to move the bottom section without moving the entire boss, I found it rather difficult as the tank section over corrects on top of you VERY easily. This is especially true if he casts spinning up directly in the MT's face.

Since we started doing this we haven't seen any 'buggy' laser barrages.

 

Lucinde

We run 25-men content exclusively and we spent a good few wipes to "bugged laser barrage" in phase 4 figuring out how it works. I'm pretty convinced it works like this, given that our paladin tank can keep generally keep it facing the same direction for the full direction. Also since we noticed it, the turrets have never 'bugged out' anymore. If they start on your tank, he can still move to the far edge of the turrets without spinning the bottom part and then strafe counterclockwise to avoid it.

That said, we one-shot Mimiron this week, so I don't exactly have a lot of empirical data to proof my claims with. I guess we'll see this week. I still don't think it's intended behaviour, but for us it felt controllable.
