^^ This is NOT meant to be an accurate representation of where the Malignant Growths actually spawn. It's simply meant to illustrate the idea of the "pizza slices" to look for.
Recommended comp: 2 tank 5 heal 13 dps, 4 warlocks. Boomkins are great for p2 and p3, BM hunters are good all around, and Warriors are insane for Phase 3.
There are three major changes in Mythic:
- The orbs must be dunked on BOTH sides within 3s of each other to count towards charging the Power Matrix
- Any time any type of add dies in the encounter, it spawns Ghunnies, which are essentially the same adds as the Infested M+ Affix, except they try to infect you instead of another mob.
- In Phases 2 and 3, there is a new mechanic called Bursting Boil. 3 spawn at a time, every 20s, and must be soaked by 2 players each. Soaking puts a debuff on you that lasts 30s. If you soak a Boil when you already have the debuff, you get MC’d and must be killed.
- Every player in the raid will need to run at some point in the fight
- Classes that could solo run on heroic can now still solo run on Mythic
- 2 Warlocks is a minimum for Gateway, 4 is recommended. Fight is MUCH easier with 4 lock gates.
- These get places such that the second gate is ~8 yards further up from where the first gate ends
- Each group going up needs either 2 solo classes, else 4 people. Debuff lasts 3 minutes
- Basically, set up 5 groups of 4. On each side, one person grabs the orb and clicks first Gateway. The 2nd person should be waiting near the 2nd Gateway. Person 1 passes to person 2, person 2 uses second Gateway and dunks the orb.
- Make sure orbs are dunked within 3s of each other
- If you have multiple solo-run classes, sub them in for a group of 4. This will allow your tanks to never need to run
- If you have 4 players who can solo run, this frees up your 2 tanks and 2 healers.
- Same idea as on Heroic, you need to focus on adds. Interrupt as many casts on the Cyclopean Terrors as possible, and make sure to always interrupt the Blightspreader Tendril’s Decaying Eruption
- DPS’s main targets to focus are the Blightspreader Tendril (big tentacles)
- Also passively work down the Dark Young, just so you never have 2 alive
- Priority is Blightspreader > Cyclopean Terrors > Dark Young
- When any add dies, Ghunnies spawn. These adds fixate a random player and chase them, trying to reach and infect them. If they reach you, you get a debuff. When debuff ends, you spawn 2 more Ghunnies
- Fixated players must ensure they are kiting the Ghunnies. They are stunnable, can be knocked back, and can be slowed.
- Work through phase 1 as you do on heroic, and make sure Ghunnies aren’t affecting people
- When the Power Matrix activates, stop attacking the tentacles and the Dark Young, and focus attention to the Ghunnies, because Ghunnies do NOT get stunned by the Blast
- Easiest way to handle these is to have everyone stack on a pre-assigned stack point. When the Ghunnies get close, you Ring of Peace, use knockbacks, etc to prevent them from reaching you
- AoE nuke down the Ghunnies so you go into phase 2 cleanly
- Similar strat to heroic, just with more mechanics to deal with
- All mechanics from Heroic are present and working exactly as they do in heroic
- Busting Boils
- Three red Boils spawn around the arena floor, and explode after 8 seconds, afflicting the 2 closest players to the Boil with a 30s DoT
- If you soak a second Boil while already having this debuff, you get MC’d and need to be killed
- Boils spawn every 20s for all of phase 2 and phase 3
- Only exceptions are during the Reorigination Blast, and when G’Huun casts Collapse to begin phase 3
- The “closest” term is relatively loose, as the DoT has an unlimited range
- Even if you’re 30 yards away from a Boil, if nobody else is closer you’ll still be selected for the DoT
- Bursting Boil soakers don’t necessarily need to be assigned, but your guild may find it easier to assign soak teams for each Boil soak
- Easiest way to do assignments is as Team 1 and Team 2, each with 10 people
- Rotate between Teams 1 and 2 each Boil spawn
- Having the teams consist of the entire raid ensures you’ll always have the 6 people minimum you need to soak Boils
- Additionally, you can make sure that your Power Matrix running teams never consist of 4 people from the same Boil team, which gives you guaranteed 8 soakers available for every Boil cast
- When Blood Feast is cast, all players not currently carrying the Power Matrix should get in the circle
- Nuke the add ASAP
- When the add dies, 5 Ghunnies spawn, make sure they’re controlled and focused down
- Time your Power Matrix activation so the Reorigination Blast happens immediately after the 2nd and 4th Gibbering Horror spawns
- All DPS should ignore this horror, as the Blast kills it. Focus on boss DPS
- After the 2nd Power Matrix Overload, you should be pushing into phase 3 (20% HP on boss)
Phase 3
- Burn phase, lust as soon as everyone is in position
- Tank boss in the middle of the room, have everyone spread evenly around him
- Assign spots for your 5 healers so they’re roughly equally distributed around the room
- You can handle the positioning and Malignant Growth just like on Heroic. Think pizza slices
- All mechanics from Heroic remain
- Explosive Corruption, Gaze of G’Huun, Malignant Growth, and Wave of Corruption occur just like heroic
- Only thing different in phase 3 from Heroic is the Boils, which still need to be soaked the same as they were in phase 2
- The important thing in phase 3 with soaking Boils is the “closest” to the Boil part.
- There will be times when nobody can get within 20 yards of a Boil due to the Malignant Growths on the ground, that’s O K, as long as available soakers are still closer than anyone else
- The “soft enrage” of this phase is the Wave of Corruption applying stacks of Putrid Blood. Eventually, the stacks get high enough the damage is unhealable. This is generally at 6 or 7 stacks. At that point, people will just start dying.
- One way to help alleviate a little of this is creative use of Battle Rezzes
- If nobody dies before phase 3, you’ll have 2 BRs available
- You can have your two best execute players (usually warriors) suicide themselves at 3-4 stacks of Putrid Blood by intentionally being hit with Malignant Growth
- Immediately BR when they die, and they now have 0 stacks of Putrid Blood
- These people now require significantly less healing, and will still be relatively sturdy when the raid hits 6-7 stacks and other people start falling over
- Doing this may give you that last little 1% on boss to get you the kill
