Immerseus - Druid Healing Strategy Guide

Recommended Talents for Immerseus 10M Regular.

T1 - 
   ˚  Displacer Beast -  Use this talent to avoid the 30k damage and knock-back from Immersius' water jet during swirl. Also useful to get where you're going very fast.
 

T2 - 
   ˚  Ysera's Gift -  is a great passive heal. There is a lot going for most of this fight, so having a hands-free heal going out is really nice.
 

T3 - 
These talents generally won't be used, as your priority during split phase will be healing.
However in the beginning of the fight when there are mostly Sha Puddles spawning, you can help out your DPS by using 

• Typhoon: Kicks back a group of adds and dazes them for 6 seconds. 
• Mass Entanglement: Roots multiple adds for 20 seconds, though as damage releases them it may not be the best choice unless DPS can focus one add at a time.
• Faerie Swarm: Slows a singular target by 50%, the least useful as it can only affect one target.

 The choice is yours, but Typhoon will probably be the easiest and most effective to use.

T4 - 

1.   ˚  Incarnation. is arguably the best talent choice, because it gives you instant-cast Regrowth which can give you incredible burst healing, but only once every 3 minutes.
2.   ˚  Soul of the Forest, gives a passive 100% Haste buff from using Swiftmend. This creates fantastic healing versatility for Immerseus' Split phase.

•   Swiftmend + Wild Growth to heal multiple Contaminated Puddles.
•   Swiftmend + Regrowth or Healing Touch to heal one or two Puddles very rapidly.

     

 But you really want to use your  Wild Mushroom: Bloom for healing Contaminated Puddles. 

I will explain this below.

T5 - 
Again, as you can only use these talents on enemy adds, try not to worry about using these talents.


T6 - 

1.   ˚  Heart of the Wild is a great option for this fight as you have a lot going on and the simpler your healing rotation during Split Phase the better. 
2.   ˚  Nature's Vigil on the other hand might be the best choice for extra healing and damage  during split phase.

Damage Mitigation for the end of Split Phase: Erupting Sha.

• Death Knight -  Icebound Fortitude
• Monk -              Fortifying Brew
• Mage -              Ice Block
• Hunter -              Deterrence

Icebound Fortitude or Fortifying Brew  are best because they provide a significant damage reduction without sacrificing the ability to heal.

Ice Block and   Deterrence deflect all incoming damage but prevent you from healing.

Split Phase: Helpful Healing Tips:

• Priest - Leap of Faith : Pull a friendly add back from the center pool to give yourself more time to heal it.

Detailed Immerseus Healing Strategy

Immerseus Phase:

The big watery guy is up and attacking things, he does a frontal cone AoE (lots of damage in the direction he is facing) Corrosive Blast. Only Tanks will be standing in this so you need:

 

  Lifebloom: Keep 3 Stacks applied to Tank. 
Refresh with Nourish, Healing Touch, or Regrowth.
 Lifebloom ticks proc Mastery: Harmony which increases the amount of healing done by Wild Mushroom: Bloom.

  Corrosive Blast deals 900,000 shadow damage, so watch DBM and apply Ironbark before it is cast to help mitigate tank damage.

There are two major mechanics you have to manage during this phase: Swirl and Sha Bolt.

1. Swirl:

• Spawns several moving void zones that will deal damage and knock you up in the air, you should be able to avoid these easily.
• Immerseus casts a water jet that deals 30k damage and knocks back players. The Jet always moves clockwise.
•   Displacer Beast can be used to blink through the wall rather than wasting time running away from it.

2. Sha Bolt: 

• Spawns a void zone under each player every 10 seconds. 
• Move to the outside edge of the pool, this will help you keep the pools organized and manageable.

(You can stack pools on top of each other if space is getting tight, just be careful and quick to get back out.)

Preparing for Split Phase
Do this at the beginning of the fight and repeat during each Immerseus phase:

Wild Mushroom : Place this under nearby players

Rejuvenation : Cast on multiple nearby players

Genesis : Use after casting Rejuvenation, until

Wild Mushroom: Bloom indicates that it has absorbed maximum overhealing (Shines Yellow). 

Split Phase:

Immerseus splits in to a number of light blue friendly adds (Contaminated Puddles) and hostile adds (Sha Puddles). It is your job to heal as many Contaminated Puddles as possible before they reach the center of the room and reform Immerseus.

1.  When Immerseus Splits, head towards the largest group of Contaminated Puddles. (you can see them flying away from immerseus)
2. If you have Nature's Vigil now is the time to use it
   
3. Position your Wild Mushroom close to the pool in the center of the room. Align your Mushroom so a group of Contaminated Puddles will pass over it. 
4. Stand on top of a Contaminated Puddle and use  Nature's Swiftness + Healing Touch. The puddle should be healed to full and grant a stack of Purified Residue. This restores 25% mana to all allies within 12 yards and increases healing done by 75%.
5. Once the puddles reach your mushroom, cast Wild Mushroom: Bloom and they will be instantly healed to full.

  Wild Mushroom should be placed close to the Sha Pool in the center of the room. 
The Contaminated Puddles group up the closer they get to the Sha Pool where Immerseus reforms. 
This placement maximizes the number of Puddles healed by a single Wild Mushroom: Bloom.

While you're waiting for the group of Contaminated Puddles to reach your  Wild Mushroom, move to stand on smaller groups of puddles and use:

• Healing Touch (Instant Cast) From - Tier 16 (2) (2) Set bonus.
  (The (2) set bonus will proc from using Rejuvenation on multiple targets.)
• Nature's Swiftness +  Healing Touch  
• Swiftmend +  Healing Touch
• Rejuvenation multiple Contaminated Puddles then cast Genesis for multiple direct rapid heals. 
• Now is the time to use Leap of Faith to pull an unhealed Contaminated Puddle to the edge of the room to allow healers a second chance to purify it.

(Stand on as many Puddles as possible while healing them. The Purified Residue buff stacks )


TIP: The number of healing adds increase as the fight goes on, so plan to save some of your bigger healing cooldowns ( Incarnation ) for later on in the fight.

Also note that Tranquility does not heal the Contaminated Puddles. 

Split Phase will end when every Sha/Contaminated Puddle reaches the center of the room. When any Puddle reaches the Sha Pool it triggers Erupting Sha which causes 75k damage to all players.
This is the time to use your Symbiosis talent of choice/barkskin while popping a healing cd.

When Split Phase ends, Immerseus phase will begin again. The two phases alternate until Immerseus reaches zero corruption.

I hope this guide was useful, have fun progressing!
