Heroic Spine of Deathwing 10man Resto Shaman Pov

Welcome to Dragon Soul Heroic mode for the Spine of Deathwing. In this guide, I will run you through everything you need to know about how to best utilize your Resto Shaman spells and abilities for a healing showdown.
A lot of new goodies for the heroic version of this fight. You can bring 2 or 3 healers in a 10man raid the choice is yours depending on how high or low your dps is. The reason behind that is that in the heroic version of the fight the Burning Tendons, have so much life that you will need to dps them down twice before the plate explodes. This has a lot of ruminations for your raid.
Aside from all the additional damage that you will have to deal with AKA (as taken from Icy Veins )
• Grasping Tendrils (10-man/25-man)  now deal 12,000 damage per second in 10-man difficulty and 13,000 damage per second in 25-man difficulty, up from 6,000 and 6,500 respectively. Additionally, Grasping Tendrils now slow movement speed by 50%, up from 35%.
• Searing Plasma (10-man/25-man) now deals 12,000 damage every 10 seconds, up from 10,000. Additionally, it now absorbs 280,000 healing in 10-man difficulty and 420,000 healing in 25-man difficulty, up from 200,000 and 300,000 healing respectively.
•  Fiery Grip  now deals 90,000 damage every 3 seconds, up from 60,000.
• Superheated Nucleus (10-man/25-man) now deals 30,000 damage every 3 seconds in 10-man difficulty and 35,000 damage every 3 seconds in 25-man difficulty,, up from 15,000 and 17,500 respectively.
• Burst (10-man/25-man) now deals 14,000 damage in 10-man difficulty and 28,000 damage in 25-man difficulty, up from 10,000 and 20,000 damage respectively.
you will also be confronted with the following new mechanics :
Degradation  is a stacking debuff that is applied to all raid members each time a Hideous Amalgamation is killed. The debuff reduces the target’s maximum health by 5% per stack. It has an unlimited duration and it cannot be dispelled. Note that the debuff is only applied when a Hideous Amalgamation is actually killed, and not when they are disposed of through a Barrel Roll.
Blood Corruption: Death is a dispellable debuff that will regularly be placed on random raid members. It has a 15 second duration, at the end of which it will wipe the raid. When the debuff is dispelled, it jumps to another nearby target, retaining its remaining duration. After a varying number of dispels, it will mutate into a different debuff ( Blood Corruption: Earth) when jumping to the next target.
Blood Corruption: Earth is almost identical to Blood Corruption: Death. The only difference is that when this debuff runs out, the target receives one or two stacks of Blood of Neltharion. The amount of stacks depends on how many seconds were left on the Blood Corruption: Death debuff at the moment when it became Blood Corruption: Earth. Blood of Neltharion.  is a beneficial stacking debuff that reduces all damage taken by 20% per stack. It can stack up to a maximum of 2 times per player. This debuff’s purpose is to counter the negative effects from Degradation.
Everything that applies for the first plate applies for the rest of the plates only things are getting harder and harder mostly because for every Hideous Amalgamation that you kill, you get a stack of Degradation which effectively lowers all your raids health pool by 5%. Killing 2 Amalgamations every plate landing on the second plate will find you with 10% less health and landing on the third one will find you with 20% less health. By the time you blow up the last Amalgamation your raid will be at 30% less health making it harder and harder to keep your raiders alive.

How to deal with dispelling

As a Resto Shaman you might be called to the task of dispelling. Generally its better if one healer is responsible for dispelling the new Blood debuffs. Resto Shamans have amazing tools to deal with dispelling while generating enough mana back to last them through the fight as will be explained later in this guide.
The way to handle with the new debuffs is to immediately dispel Blood Death until it has mutated to Blood Earth. Given the fact that once Blood Earth expires it leaves back the Blood of Neltharion buff, its imperative that you try and get both of your tanks 2 stacks of Neltharion buff as soon as possible. Again the way to do that is to keep dispelling Blood Earth until it lands on one of your tanks. After you have secured 2 stacks of the buff to each of them you can move on and let it naturally expire to the rest of your raid. I try to apply at least one stack after that to each of my raiders choosing the weakest one to start with. If you find you simply don’t have time or mana, you can opt out but when a member has 2 stacks you should dispel it in favor of someone with zero.
TIP : Blood Corruption: Earth used to mutate back to Blood Corruption: Death if it was dispelled enough times. This was hotfixed or hushed away at some point so you don’t need to worry about wiping your raid. Once Blood Death has mutated to Earth it will never mutate back again.
TIP : For this fight specifically it’s very important to be able to properly handle Blood Corruption: DeathBlood Corruption: Earth  AND navigate yourselves successfully in a way that you will land Blood of Neltharion  buff to the appropriate targets as soon as you possibly can. Blood Death and Blood Earth both will show on top of your Vuhdo depending your configuration but Blood of Neltharion and especially its stacks will not. The way to easily deal with dispels is the following :
Add a distinct color on your raid frames to help you identify and separate Blood Death that will wipe your raid with Blood Earth. Vuhdo will recognize them both as debuffs and assign then with the same color, making it harder for you to identify them in the heat of the moment. I chose to color Blood Death black and left Blood Earth as it was. Below is a screenshot of how my Vuhdo looks like :

Notice that both of my tanks have 2 stacks each of Blood of Neltharion ( stacks are showing in the middle of each players frame ) and how there is one Blood Death already applied on one of my fellow healers. This way its easy for me to know immediately what kind of debuff is applied to which raider , who to dispel and in which priority. Below is my Vuhdo configuration needed to achieve these 2 effects.

Blood of Neltharion is not currently included in the default Vuhdo buffs. You can easily bypass this by adding it yourself. On the panel below simply click on the Enter new Buff os Debuff Name field and type Blood of Neltharion. Make sure the rest of the properties match the screenshot below and click on Save followed by Okey.

Suggested Raid Composition

2 Tanks – 2 Healers – 6 Dps  or  2 Tanks – 3 Healers – 5 Dps. This depends on how strong your healers are or how strong your dps is.

Gear and Reforging Check

For this fight any mastery oriented gear will do again. Personally though I retained my 2005 haste rating since my gear allows me to sustain that haste while stacking enough mastery.
Equip your talent tree with Telluric currents to get mana back as well as do damage and Focused Insight to be able to amplify your healing throughput. Remove all points from Enhancement tree to facilitate more mana gain adding the rest of the points to the Elemental tree as seen below.
Instant ghost is not needed for this fight and if you are in charge of dispelling you will need to amplify your mana back from Telluric currents as much as possible. Be sure to add maximum points to Improved Cleanse Spirit and Cleansing Waters. Don’t be afraid to drop points from Ancestral Awakening , since you will be mostly running with Healing rains on CD you will barely get an procs of that. On my kill AA only contributed 1.6% of my total healing. Also the difference between adding 2 points to Cleansing Waters is about half of your mana pool. While I was specced out of it after I was finished with my dispelling I was left with barely 30% of my mana, whereas spending 2 points on that talent left me with 60 to 70% of my mana.
 Below is an example of how your talent tree should look like.

Below is an example of how your character should look like. Gear, reforging, talent tree and glyphs included.
CharDev Example with 404 gear and reforge details
Haste in this example is as close to 2005 as it gets.
Mastery should be above 19 or as close to it as possible for the extra healing it will provide you.
Spirit is little below 3300 (counting the proc from  Heart of Unliving) in order to have plenty to meet your needs.
All items used are from Normal and Heroic Dragon Soul.This is how my character looked like when I got into the fight, you might go into it with more of less gear. As always, if your gear is different just apply the rules above for potential reforges.

Fight starting in 5..4..3..2..1. Pull.’

First Plate. Before you start the fight make sure to earthshield the tank. As soon as you cut off the cinematic drop your totems and use any shock spell of your choice to any  Corruption . Drop a healing rain in between the stacking side where your raid will perform a roll and riptide any member affected by Searing Plasma .(More and more will be affected always start by casting a riptide on them if its of cooldown.) After casting healing rain start relocating to the stacking point and make sure you are gripped. Cast another shock spell to any corruption and depending on your timing either cast another healing rain at your location and drop spirit link totem or vice versa. At that point the rest of the healers will be probably be using their raid cooldowns too. If you are responsible for dispelling get ready to dispel from 1 up to 4 Blood Corruption Death from your team.
TIP: Before starting dispelling, make sure you have 10 stacks of spirit procs from your Heart of Unliving trinket if you have it, and drop your mana tide totem. It will help you as well as the rest of your healing team regenerate as much mana as possible while save you a lot of mana too. Using this method I am left with more than 70% mana after I am done with dispelling if not even more.
The Blood Death debuffs, will all start at 15sec and every time you dispel them that time will decrease. The debuffs will not all start at the same time but very close together so make sure to always dispel the one that has the least time left. At this point you need to concentrate at first getting rid of any Blood Deaths as they will cause an instant wipe if their timer runs out. As soon as they start mutating to Blood Earth you will need to try and dispel them from every member they might jump to until they land to any of your tanks and let them safely expire there. When they expire they will leave each one stack of Blood of Neltharion buff.Once you have 2 stacks on each of your tanks you can let Blood Earth expire in any member of your choice.
TIP: Its very hard to get both of your tanks to have 2 stacks each at the first plate but doable. However if you are straggling for mana make sure the tank that is responsible for tanking the bloods has priority and also make sure that you wont get to the third plate without having 2 stacks in each tank since they will require more and more healing.
Use your Spiritwalker’s Grace to take advantage of the 4pc bonus that will give you extra haste and begin a rotation of
1. Casting lightning bolts to the Amalgamation your tank is tanking while,
2. Making sure you keep up with his earth shield
3. Your own water shield
4. Recasting any missing or destroyed totems
5. Casting riptide on cooldown if possible on any members that just got the Searing Plasma debuff or the tanks if everyone is off the loop
6. Throw any shock spell of your choice at the Amalgamation and cast either healing rain or greater healing wave to whichever member has the highest stacks of Searing Plasma. You will be able to rotate through those 2 if you keep your cool. Note that of course you can break this theoretical rotation at any given point that a) any member is gripped for more than they should since you will need  to shock heal them to keep them alive, b) if for some reason the tank needs extra healing.
Keep following all of the above up until the first Amalgamation explodes. As soon as it does your dps will kill the last Corruption thus landing you with a Blood Death debuff to dispel. Be ready for it but at that point you don’t need to panic like before , if you handled 4 earlier this one will seem like a walk in the park. If you used your Spiritwalker’s Grace when I suggested earlier then you will have it again shortly after the first round of handling one of the Burning Tendons. Continue as above until the second Amalgation exlodes and deal with one more Blood Death dispel.
TIP: Try and dispel as much as possible and experiment at the first plate where healing is not as intense. You will notice the difference as soon as you step on the second and third plate when you will need to heal more and you wont have to deal with as many dispels.
Second Plate. Same exact logic as with the first plate with 2 differences.
1. You will notice that its much harder to keep your raid alive while rolling. Make sure your timing at dropping spirit link totem is on the spot.
2. There will be one less Blood Death to deal with since now there are only 3 Corruptions to kill.
3. You might get a delayed Blood Death debuff applied so I suggest waiting a few seconds before popping your Spiritwalker’s Grace. You want to take advantage of that haste in order to get as much mana back as possible and wasting it while you are dispelling will reflect on your regeneration.
4. Overall dealing with Blood Deaths will be easier because a.) They are less and b.) You will most likely have already dealt with applying stacks to the tanks so as soon as they mutate to Blood Earth you will not have to worry about them anymore.
Third Plate. The hardest plate to handle since you will have 20% reduced health pool and an immense amount of bloods that are threatening to either kill your tank or get out of aggro control. Be ready to heal fast whomever needs it and try to always be in control of the Searing plasma debuffs. It’s very easy to lose a member that is gripped at this point due to the fact that he wasn’t knocked out fast enough while having a high amount of time still remaining on his Searing plasma debuff along with his 20% or 25% reduced health pool. Be on the lookout for any bloods running towards you and if this happens run towards the tank that is supposed to tank them in order for him to take aggro of you. As always remember you need to dispel an additional Blood Death when the Amalgamation dies.
This concudes this guide for the Spine of Deathwing HC .Enjoy the fight and happy looting!
I will leave you with a screenshot of my UI while in fight for a better understanding of how important it is to configure your Vuhdo before hand. Numbers are flying and generally its chaotic so the easier you make it for yourself to successfully dispel without errors the better it will be for you and your raid.

Heroic Warmaster Blackhorn 10man Resto Shaman Pov

Welcome to Dragon Soul Heroic mode for Warmaster Blackhorn. In this guide, I will run you through everything you need to know about how to best utilize your Resto Shaman spells and abilities for a healing showdown.
Once again Blizzard is not failing to fail us at what a heroic version of a fight should actually entail. Bring back Ragnaros HC! That was an amazing idea. In any case lets get back to boring funship. You are now faced with the fact that, besides everything that is going on around you, flames are spurring under your feet that eventually npc’s will extinquish. Of course, the ship is after all being attacked. What is more Goriona will also land on second phase. Other than that, its another day at Dragon Soul as usual.
Strategy-wise this is yet another heroic fight where you need to drop one healer in favor of one dps. Be prepared to discuss your raid cooldowns with your fellow healer and your tanks. You will need to rotate them for every Twilight Onslaught that Goriona lashes at you.
TIP. There are reported bugs of the fire visually stacking on the deck while physically is not doing any damage. It’s hard to guess where those patches would be making stirring around them very difficult. A solution is to reset the mode to Normal and then set it back to Heroic. This will momentarily fix the bag but it’s bound to be back with a vengeance. Also, you can’t switch back and forth instantly , you need to wait 5 min, so take your regular breaks on those resets.
While not many things change you need to be careful of how people absorb those Twilight Barrages, since now they are placing a 15 second debuff on players that increases shadow damage taken by 50%. This debuff can stack. So always put 2 people on each one that don’t already have it. It’s easier than it sounds. You don’t actually have to absorb that many.
TIP. Do not absorb any before any Twilight Onslaught unless you have to and absolutely avoid any Blade Rushes from  Twilight Elite Dreadblade and Twilight Elite Slayer adds.
During phase 2, Goriona will land and she needs to be tanked. She has two abilities during this phase:
  •  Twilight Breath (10-man/25-man), which is a standard frontal cone breath attack;
  •  Consuming Shroud (10-man/25-man), which is a debuff that Goriona regularly places on a random (non-tank) raid member. The debuff absorbs a moderate amount of healing (100,000 in 10-man and 150,000 in 25-man). Any healing done to players affected by the debuff is also mirrored as damage to the entire raid (except for the player affected by the debuff, who does not get damaged). For example, a 5,000 heal on the player will deal 5,000 damage to each raid member.
TIP. You will want to utilize as much as possible of your AOE heals for this phase.Healing rain is excellent since you can position it to include all 10 members of your party if not at least all the ranged that will be stacked on you. Move in unison avoiding Shockwaves.Put down 2 markers that will be at the far edges of your healing rain.These will serve as the outmost points where your raid will stack. When a shockwave hits one just move to the other.

Fight starting in 5..4..3..2..1. Pull.’

First Phase.
Drop your totems in the middle of the deck and try to refresh them there or as close as it gets to the middle when they expire or you replace them. Remember to keep your riptides rolling on the tanks or whoever needs it. Shock one of the two adds with any shock spell of your choice and lay on their feet a healing rain. Use greater healing waves to heal up any of your party that didn’t move from the blade rushes (although they really should). Spam lightning bolts in between heals.  By the time the rain is expired the first Twilight Onslaught will have made its appearance. If you are in full mana you are doing this correctly. Shock any remaining adds to get your healing rain amplified and ghost wolf towards the Onslaught.
First Twilight Onslaught. Immediatelly after you are in position start casting Healing rain.If you are designated to use your spirit link totem drop it after having cast your Healing rain. This way you get the most out of both spells. If however you find you don’t have time to do both , start by dropping your spirit link then cast healing rain. Try to coordinate yourself however, you will need the extra ticks from the rain before people spread out of it. As soon as Twilight hits, cast 2 or 3 chain heals starting from the lowest always party member and then move out of harms way. While running as always feel free to cast riptides on CD and unleash life.If your tanks need a boost or another party member cast a greater healing wave. As soon as your healing rain is over spam a shock spell to any add and drop another one on the tanks feet.
Second Twilight Onslaught. As always ghost wolf your way towards it, cast an amplified healing rain and if you have time either refresh riptides or cast lightning bolts. As soon as twilight hits drop your Mana tide totem and your Spiritwalker’s Grace and get the hell out of harms way while you chain heal members. Remember if everyone is safe you want to keep trying to fit in as many lightning bolts as you can, you need to get into the second phase with more than 50% mana.
Rinse and repeat for as many Onslaughts you may get although you shouldn’t get more than 4.
Second Phase.
Stay away from the rest of the dps so you can heal them without getting into any of the nasty pools that Goriona leaves on the ground. Ideally you won’t get more than one however. At this point immediately after the tank taunts her and face her away from the raid you will need to stack as close as you can get to one of your prepositioned marks. At this point rotate between your CDs as soon as they are ready, spiritwalkers grace, mana tide totem, spirit link totem. Drop amplified healing rains to your location and in between your marks so it covers them both. Keep dropping healing rain on cooldown, keep members up with chain heals, heal anyone in danger with greater healing waves and help out the tanks similarly. Save your instant greater healing wave to rescue the tank in need. Things to note. You WILL have to find time to unleash life in between all of this panicked healing but always make sure you do it before casting a greater healing wave. Its very important that you keep spamming any add with lightning bolts so you can keep your mana up. With only two healers this fight is bound to take every bit out of your mana pool.
This concudes this guide for the Warmaster Blackhorn HC healing showdown. Enjoy the fight and happy looting!

Heroic Warlord Zon’ozz 10man Resto Shaman Pov

Welcome to Dragon Soul Heroic mode for Warlord Zon’ozz. In this guide, I will run you through everything you need to know about how to best utilize your Resto Shaman spells and abilities for a healing showdown.
I don’t like the fact Blizzard felt we had to fight 2 bosses in the same room. I always feel I’ll either get oozes to spawn or tendons and vice versa. Its disorienting to be in the exact same environment but whatever. Thank you Blizz.
Zon’ozz on heroic features one main difference that will brighten your day. Remember those adds that spawned during black phase? What? You were too busy healing like crazy/ dpsing like crazy/tanking like crazy to remember? I have excellent news for you!They were there! And guess what! You get to fight them in heroic version. Excited? No? You’re more like me then. Hard audience. I’ll just get right to the point.
While the ping pong phase remains almost the same ( my suggestion will be to go for 5/5/5 then kill / kill / kill ) be prepared for even more damage to the tank and get ready to deal with the Disrupting Shadows  debuff that now not only deals damage to the affected raid member but also to all raid members within 10 yeards.If and when you get it, it move out of range and dispell.Rule of thumb.
Tip. If you don’t have an addon to display range, Blizzard has its own.Input the following in chat to get yours to pop out.
/range 10
In regards of the new adds that will spawn.
Claw of Go’rath is a large tentacle that must be tanked. If not tanked, this tentacle will deal massive amounts of damage to the raid, causing a fast wipe. 1 Claw spawns in 10-man difficulty. The Claw of Go’rath deals very low damage, and does not need a proper tank. Plate wearing DPS players and Feral Druids can perform this task.
Flail of Go’rath is a small tentacle with little health. It deals damage to random raid members and performs a knockback on players within 15 yards of it. 2 Flails spawns in 10-man difficulty.
Eye of Go’rath simply deals damage to random raid members. 5 Eyes spawn in 10-man difficulty.
Although you should take a look in the videos below for more info on how to handle these adds, my raid has the following strat. As soon as Black phase begins everyone should stack on the Claw .This way healers can lay down all their aoe heals while the tank will take upon the task to tank both the Claw and Zon’ozz. As for the dps assignments. 2 dps will take the closest Flail to their side while another 4 dps divided in 2 groups will take the closest eye to their side. Once those 3 are dead, the group that got the Flail down will split from the group taking one healer with them in order to kill 2 remaining eyes on their side, one of the other 2 dps split to the opposite side to deal with another 2eyes with yet another healer and the last 2 dps along with the last healer will remain in the middle (should be melee) in order to take down both the claw and dps the boss as much as possible. Rinse and repeat 3 times. On the forth pop Heroism , stack on the Claw again ( the tank still needs to tank both of them ) ignore all adds and dps down the boss. Needless to say it’s yet another dps intensive fight and healer likewise.

Suggested Raid Composition

1 Tank – 3 Healers – 6 Dps

Gear and Reforging Check

For this fight any mastery oriented gear will do, mainly since during Black phase the Black Blood of Go’rath   debuff that exists in normal mode works slightly differently. In heroic mode, this debuff gains stacks, and deals damage to the raid based on the amount of stacks it has (around 4,000 Shadow damage per second per stack). Each tentacle that is alive (Claw, Flail and Eye) applies one stack of the debuff. Killing the tentacles is required in order to lessen the raid-wide damage .It is important to note that the debuff does not deal damage to the raid outside of the Black Phase, but it maintains stacks based on how many tentacles are still alive during this time. When the next Black Phase starts, these stacks will be added to the stacks of the newly spawned tentacles, resulting in higher damage. What this means is that the whole raid will take huge amounts of damage that will bring each member to its feet, namely for the most part of the phase below 50% of their health.Shaman mastery healing here will work wonders while you are progressing, feel free to change to haste after your first kills.
Equip your talent tree with Telluric currents to get mana back as well as do damage before the Black phase and Focused Insight to be able to amplify your healing throughput.
Remove points from your ghost wolf since for this fight you probably will be called to dispel a lot so put some talents to your Improved Cleanse Spirit and Cleansing Waters. Don’t be scared to lose your instant wolf. You will only be running a short distance and at that point you will be sporting Spiritwalker’s Grace anyways.

Below is an example of how your character should look like. Gear, reforging, talent tree and glyphs included.
CharDev Example with 397 gear and reforge details
Haste in this example is as close to 916 as it gets. I’ve removed all extra haste to amplify my spirit and mastery needs.Also the only time you will really need haste will have heroism and spiritwalkers grace to compensate.
Mastery should above 20 or as close to it as possible for the extra healing it will provide you for when your raid hits all time lows. Mastery is a must in this fight since while in Black phase your raid will always be below 50% of health.
Spirit is little above 3800 (counting the proc from  Heart of Unliving) in order to have plenty to meet your needs.
All items used are from Normal Dragon Soul.
As always, if your gear is different just apply the rules above for potential reforges.

Preparation Tips and Tricks

Make sure your weapon is imbued with Earthliving Weapon enchant and your Water Shield is up . Put Earth Shield on the tank and try to keep it up at all times .Start overhealing the tank so that your well spent Ancestral Healing talent points will proc that wonderful 10% damage reduction and 10% maximum health pool increase. After you see you can’t climb more on their health cast riptide on him. As long as riptide is ticking the stacks will never drop thus securing the tank an extra 10% damage reduction and health pool increase throughout all the fight.

Fight starting in 5..4..3..2..1. Pull.’

 TIP. Depending on what healers your raid is sporting your assignment will differ. Below is my view of the fight from my POV so my spells are adjusted accordingly. I’m stationed in between the melee pile and the ranged pile for 3 reasons.
  First so I can spot heal the tank if needed while I’m keeping my earth shield on him  and also provide support for the melee pile (with healing but also with dispelling)  whilst I am also responsible to take care of my ranged team. (Not as scary as it sounds. Restoration shamans are amazing at multitasking like this. ) 
Second so I am close enough to roll lightning bolts at the boss to regain my mana as this is the only time you will be allowed to do that. 
Third so I am close to enough to spam the shocking spell of my choice to take advantage of my Focused Insight talent and amplify my heals. 
Run in and drop your totems at your position after the tank pulls. If you run in before the tank you risk engaging the boss . 
TIP. Relocate for the unfortunate event that the Void of the Unmaking spawns towards your direction since it may bounce of your totems. Relocate yourself accordingly allowing the ranged pile to assume your position in that case.
At this point there is no significant damage going out, help the tank healer with the tank, refresh your riptides to members that need it and roll some lightning bolts at Zon’ozz. As soon as you see the Void spawning you have few seconds to :
1.Shock the boss with any shocking spell of your choise and
2.Depending on where you see the ball is heading lay a healing rain under the feet of the ranged pile. This way your healing rain will be 30% stronger.Yes I can’t stress this enough, all it’s ticks will be 30% stronger so consider your GCD well spend.
Ping Pong Phase.
While in this phase make sure there is a healing rain under the ranged pile at all times always enhanced with any shocking spell. So cast it on cool down . Cast riptides on CD also and if you feel your melee pile needs more love cast chain heals to an non riptided member.Turn your attention to the tank and make sure he survives Psychic Drain and is topped off after. Since you keep rolling your riptides on CD and chain healing the melee pile your tidal waves will be up to give you 30% more crit chance to your healing surges and 30% faster greater healing waves. So if you are unsure of your tank cast 2 healing surges at him to keep him alive long enough so you can cast your greater healing wave at ease.
Note. Your tank healer will probably be on top of this so you won’t need to stress as much. Use this time to cast lightning bolts if you can.
Black phase.
As soon as black phase starts the boss will automatically teleport in the middle of the room. At this point there is some dead time where you need to run to your location which is stacked under the Claw with the rest of the raid. You should :
1. Make sure your tanks earth shield has enough stacks, if its under 4 refresh it on the run.
2.Spam once Unleash life on the tank and spam any shocking spell at the boss to activate your Focused Insight proc and pop your Spiritwalker’s Grace. Immediately start casting healing rain at the stacking location.By the time you are finished casting you’ll already be there.
3.In accordance with your fellow healers this is the time to drop your spirit link totem. You can only drop it every other Black phase so either you’ll be called to drop it on 1rst and 3rd adds or 2nd and 4rth.
4.Drop mana tide totem to regain mana while you’re casting and keep dropping it on cd after this. Like spirit link totem it will be back for a black phase again.
5.Shock the claw or the Zon’ozz and cast another healing rain at the melee pile.
Note.Remember. You will be called to dispel Disrupting Shadows every now and then.Remember to check if your raid member is in a safe 10 yards radius before you do.
Now depending on your assignment you will be either staying with the melee pile or called to heal a ranged group that will split after the first adds are down.
Melee group assignment
Shock either the Claw or Zon’zz and cast healing rain on CD. Keep your riptides rolling on whichever member needs it and keep the tank up with greater healing waves. As always if you see any member running low especially the tank cast 2 healing surges to secure them quickly before you lay a bigger spell. Occasional chain heals might help although they are not my preferred spell for this situation.
Ranged group assignment 
Transfer your earth shield to any ranged of our team. You heal more any member that you have earth shielded via this talent Nature’s Blessing . Spot heal them with healing surges and greater healing waves.
TIP.Keep your riptides rolling on CD. Yes the GCD is always worth it.Not only they will have a HOT on them to keep them going but this way you’ll always get to keep your tidal waves up making your greater healing waves 30% faster and give your healing surges 30% chance to crit. Overall win win.
Once the Black phase is over relocate to your original assigned position. Top off any member needed. If its ranged pile lay a healing rain, if its melee chain heal or spot heal of your choice.Remember to earth shield the tank if it has either run out or you had it on a ranged member. Assume your “healing rotation” since at this point effectively you are at the beginning of the fight again. Rinse and repeat 4 times.
Fourth set of adds.
 As soon as the 4rth series of adds spawn  pop Heroism and stack on the Claw again .Everyone at this point will ignore all adds, except for the tank that will still need to tank both the Claw and Zon’ozz. This will be very intense healing phase seeing as the adds will keep damaging your raid constantly until the boss dies. Your mastery is going to help you with this phase keep casting healing rains at your location and chain heal in between. Hopefully you will have enough mana to keep you going until its over.
This concudes this guide for the Warlord Zon’ozz HC healing showdown. Enjoy the fight and happy looting!
