Comprehensive Strategy Guide by Icyveins

herioc text from icyveins guide

8. Heroic Mode ↑top

The only significant difference between the Heroic mode and the Normal mode is that Yor'sahj will spawn 4 oozes instead of 3. Since you can only kill one, it means that you will always have to deal with Yor'sahj being empowered with the abilities of 3 oozes, instead of 2.

Other than this, all abilities deal more damage and all units (Yor'sahj, oozes, adds, and Mana Void) have more health.
8.1. 6 Possible Ooze Combinations (Again!)

There is a total of 15 possible combinations. However, just like in Normal mode, Blizzard made it so that we would only see 6 combinations:

black — blue — green — purple;
black — blue — green — red;
black — blue — purple — yellow;
black — green — red — yellow;
black — purple — red — yellow;
blue — green — purple — yellow.

8.2. Ooze Priority

The general ooze priority is yellow > green.

We believe that there should be two exceptions to it:

black — purple — red — yellow: kill purple instead of yellow, this will enable you to heal through the extreme damage;
black — green — red — yellow; kill green instead of yellow, this will enable you to stack up on the boss and efficiently heal the extreme damage.

8.3. Strategy

If you are attempting the Heroic version of this fight, then you should be familiar with what the oozes do and how to deal with them. The fact that the boss is buffed by 3 oozes does not add complexity to the fight. It looks as if the possible combinations were carefully chosen so that you would have to perform exactly the same variety of tasks as in normal mode: stack on the boss, spread out, handle Deep Corruption Icon Deep Corruption, DPS the Mana Void, and DPS the Forgotten Ones. What the third ooze invariably adds is more raid damage.

In any case, we will not delve further into the strategy part, as it is really the same as in normal mode. The key to winning the fight is to properly handle several things:

heal the extreme damage caused by having black, red, and yellow at the same time;
have the healers not blow the raid up when purple is up;
strike a balance between attacking the boss and killing the various adds (oozes, Forgotten Ones, and Mana Void), as we explain below.

8.3.1. Black, Red, and Yellow

This combination of oozes will be the hardest to heal. Fortunately, since the raid will be stacked up on the boss, AoE healing cooldowns should be kept and used for this combination: Power Word: Barrier Icon Power Word: Barrier, Spirit Link Totem Icon Spirit Link Totem, Aura Mastery Icon Aura Mastery, etc.

Note that this combination can come twice or thrice in a row, meaning that your raid should try to use AoE healing cooldowns sparingly, only when necessary. This will enable you to survive the bad odds that come with getting this combination several times in the fight.
8.3.2. Deep Corruption

Your raid will have to deal with purple in half of the possible combinations (using our kill priority). This means that, unlike in Normal mode, properly handling Deep Corruption Icon Deep Corruption is no longer optional.

This debuff will stack on players every time they get a heal or receive an absorb effect. At 5 stacks, the player will explode and deal a massive amount of raid-wide damage.

To properly handle this debuff, healers must have it show in their raid frame addons (the spell ID is 105171 and its name is Deep Corruption).

Also, purple is always up in combination with blue, which deals no damage, and either of black or green, which deal very moderate damage. As you can see, purple is never combined with a highly damaging ooze that would cause the healers to panic, so they should be able to easily keep every player in the raid alive, without having to heal them more than 4 times.
8.3.3. Beating the Enrage Timer

Most guilds progressing on Yor'sahj Heroic will find the 10-minute enrage timer to be very tight. As we will explain in this section, precious seconds can be saved in the way you will handle the oozes, the Forgotten Ones, and the Mana Void.

Killing the oozes might not require the entire contingent of DPS. The idea is to kill the ooze close to the boss, and not half-way through (which would mean that some DPS that were sent to kill it would have been better employed on the boss).

It takes the oozes approximately 23 seconds to reach the boss, from the moment that they spawn. This means that you need about 110k DPS on the ooze in 10-man difficulty and 360k DPS in 25-man difficulty. These values should be used to determine exactly how many DPS should be sent to kill the ooze (some classes can do high burst damage, take it into account).

When the Forgotten Ones spawn (something that happens in all combinations, save one), DPS players should not specifically AoE them down. Rather, only classes that can spread their damage on the boss to the adds (for example, Combat Rogues with Blade Flurry Icon Blade Flurry, Fire Mages with Impact Icon Impact and Combustion Icon Combustion) or that can spread their damage on the adds to the boss (for example, Warlocks with Bane of Havoc Icon Bane of Havoc, Enhancement Shamans with Lava Lash Icon Lava Lash, Improved Lava Lash Icon Improved Lava Lash, Flame Shock Icon Flame Shock, and Fire Nova Icon Fire Nova) should bother with the Forgotten Ones.

Dealing with the Forgotten Ones in this way means that they will remain alive longer, which increases raid damage (or tank damage, if the tank managed to taunt them before they fixated on someone).

Finally, you can ignore the first Mana Void (try getting it to 20-30% by the time the next set of oozes spawn) and use cooldowns such as Hymn of Hope Icon Hymn of Hope or Mana Tide Totem Icon Mana Tide Totem after it has depleted all casters of their mana.

The idea is to survive with rather low mana for one phase or two, until you get a second Mana Void (something that should happen quickly enough as 4 of the 6 combinations have blue). Then, as soon as the second Mana Void has depleted all casters of their mana, the first Mana Void should be killed. Hopefully it will be on low health, after taking a bit of damage now and then.

After that, you should keep the second Mana Void as a means of re-filling your raid's mana after the third Mana Void spawns and so on. All in all, this will save you the trouble of killing one Mana Void. Since they have a significant health pool, this will prevent you from wiping to the enrage timer at 2% health.

three healers right? yep.

Be prepped and ready to do this tonight.

Healers, make sure your frames show Deep Corruption, as you will be doing this fight without healing over 5 times. If your heal set up does not show Deep Corruption and it's stacks, then make sure it does before tonight. Spell ID is 105171.

This is also for you too Mazz. We may toy with you healing this, as Skruey has 4 set which would be very beneficial... as well as having Proph being Shadow, another ranged over a melee DPS will also be beneficial.

LIKE A BOSS, Yeah pretty sure I can heal stuff . I assume my UI works with that debuff. I guess I won't really know until the fight but I don't anticipate any issues. 4pc is nice. We'll see how hard he hits and how bad the stack is on the tank in heroic. I must say I do have pretty decent AOE healing which would help in certain situations. Though my gear is lacking a bit.

Looks fun, we down this and Morchokie tonight I will buy everyone a smelly sticker!

Holy pallys are kings for this fight. Beacon does not cause stacks nor does WoG. So essentially Beacon tank Divine light and Holy shock the raid members when needed and WoG the tank if shit gets scary.

Other healers will Be assigned groups to Heal.

I was hoping to compile a list of abilities and whether or not they add stacks of Deep Corruption to help with H Yor'sahj where letting the purple ooze go through is often preferable.

I've been busy reading threads and below is what I've compiled. Thanks to anyone who has ever posted their findings in a thread related to Yor'sahj and the purple ooze. I'd love to fill in the blanks and add more spells where it might be debatable how many stacks they add so please feel free to contribute!

My research so far:

Druid
Effloresence - NO STACKS (I'd love to get this checked as my guess is it's supposed to act like Healing Rain/Holy Word: Sanctuary and give a stack on entry).
Lifebloom - 1 stack per cast. (NO STACKS on bloom)
Rejuvenation - 1 stack on initial application
Swiftment - 1 stack on the person swiftmended.
Tranquility - 1 stack per tick (i.e. a raid killer)
Wild Growth - 1 stack for each person hit by Wild Growth

Shaman
Chain Heal - 1 stack for each person it bounces to.
Earthliving - NO STACKS
Earth Shield - NO STACKS
Healing Rain - 1 stack upon entering. If you leave and re-enter, you gain another stack.
Healing Stream Totem - NO STACKS
Riptide - 1 stack on initial application
Spirit Link - NO STACKS (Although one report of it blowing up the raid. More info needed).
Unleash Elements (Earthliving) - 1 stack

Paladin
Beacon of Light - NO STACKS
Guardian of Ancient Kings - NO STACKS
Lay on Hands - NO STACKS
Holy Radiance - 1 stack for initial application (i.e. if it hits 4 people, 4 people get 1 stack).
Word of Glory - NO STACKS

Priest
Atonement - 1 stack
Binding Heal - 1 stack to the person you heal. More testing on whether stacks on the Priest.
Desperate Prayer - NO STACKS
Divine Hymn - 1 stack per tick (i.e. will wipe your raid)
Echo of Light (Holy Mastery) - NO STACKS
Guardian Spirit - ??
Holy Fire (with Atonement) - 1 stack per tick. Do not use if you have atonement.
Holy Word: Sanctuary - 1 stack upon entering. If you leave and re-enter, you gain another stack.
Holy Word: Serenity - 1 stack
Lightwell - 1 stack per buff gain (i.e. when the person clicks)
Penance - 1 stack for the whole channeled cast (i.e. not 1 per tick)
Power Word: Shield - 1 stack (even when glyphed)
Prayer of Healing - 1 stack
Prayer of Mending - NO STACKS
Renew - 1 stack on initial application (Renewing Renew in Serenity Chakra with a direct heal only adds 1 stack from the direct heal and none from the renewing the Renew. Yes, there are probably better ways to express this).

Other Abilities

Generally, most other abilities that are not used by a healing class will not add a stack.

Deathknight Anti Magic Zone - Possibly adding 1 stack per person under it.
Deathknight Bloodwordms - 1 report of adding stacks. Need more info please!
Deathknight Deathstrike - no stacks
Deathknight Death Pact - no stacks
Deathknight Rune Tap - no stacks
Druid Leader of the Pack - no stacks
Hunter Chimera Shot - no stacks
Mage Glyphed Evocate - no stacks
Paladin Divine Storm - no stacks
Priest Vampiric Embrace - no stacks
Rogue Recuperate - no stacks
Warlock Drain Life - no stacks
Warlock Fel Armor - no stacks
Warlock Healthstones - no stacks

Dranei Gift of the Naaru - 1 stack

Healing Potions - no stacks
Mysterious Potion - possibly a stack

Set Bonuses, Trinkets and Weapon Procs
No stacks. Use your Maw of the Dragonlord with no fear!

Abilities that Affect Stacks
Mage Ice Block - Clears stacks
Paladin Divine Shield - Still gives stacks

Further information needed for Hand of Protection.
