Immerseus is stationary in the middle of the room, he has a corruption bar which needs to be reduced from 100 to 0 to kill him and has 2 phases:
Phase 1: Boss phase
During phase 1 you will fight the boss himself, he has a relatively low health pool and has the following abilties:
Sha Bolt is an ability that Immerseus uses roughly every 10 seconds. It deals moderate Shadow damage to every raid member (and to anyone within 5 yards of them), and places a small void zone at their location. These void zones persist until the end of the phase. When the phase ends, the void zones will move towards Immerseus and disappear upon reaching him.
Swirl is an ability that has two components. Immerseus will summon a number of small void zones that move around the room, dealing damage to any players who come in contact with them, and knocking these players up in the air. Immediately afterwards, Immerseus will channel a very damaging jet of water in front of him, and he will spin clockwise for 10 seconds. After the 10 seconds are up, the void zones will disappear and Immerseus will resume his usual behaviour.
Corrosive Blast is a frontal cone attack that deals Shadow damage to affected players, and debuffs them to take 300% increased Shadow damage for 45 seconds. This effect stacks. Immerseus casts this ability every 35 seconds or so. This ability requires a tank switch.
Seeping Sha is essentially a protective barrier that surrounds Immerseus (displayed as a ring of water). Players who get too close to the boss and enter this water take damage and are knocked back. This prevents players from walking through the boss, but since his hitbox is very large, it does not interfere with melee players' ability to attack.
I pulled the above descriptions straight from Icy veins.
The Sha bolt ability means that you will have to be spread out, and will be responsible for taking up as little space as possible with the void zones, these spawn at your feet when the ability hits you and all you have to do is move out of them, and prepare to move from the next one. Overlapping these will provide the most space to move around and thus prevent accidently walking in puddles(hopefully).
The Swirl ability will just spawn many swirly pools that move around the room, just avoid these, swirly pools are like fire, fire is bad.
Corrosive Blast is simply a frontal cone tank switch, don't stand in front of the boss.
Seeping Sha just prevents you from going into the pool in the middle...you never need to anyway..he has a large melee hit box, I have no idea how this will effect charge/shadowstep/killing spree....we will see.
These abilities continue until you "kill" the boss, at which point phase 2 begins.
Phase 2 (split phase):
Phase 2 is the phase where you actually kill the boss, phase 1 is just forcing him to this phase. The boss dies when he reaches 0 corruption. The only way to get rid of corruption is to deal with adds that spawn in this phase:
Sha Puddles: This is the add that must be killed, they do not need to be tanked, they don't do damage, they simply run towards the boss. Kill these before they reach the boss or there is moderate raid wide damage, they can and should be stunned and rooted.
When A Sha puddle is killed all players within 10 yards gain 25% increased damage to Sha puddles for a limited time, this effect stacks.
Contaminated Puddles: This is the add that must be healed, upon reaching the boss it does moderate raid wide damage if it is not fully healed, minor raid wide damage if it has been fully healed
When A contaminated Puddle is fully healed, all players within 12 yards gain 25% of their mana, and gain a 75% increase in healing done for a short time; this effect stacks.
For every add that is killed/healed respectively, the boss loses 1 corruption, when he reaches 0 corruption the fight is over, you win.
It's rinse and repeat phase 1 --> phase 2 until the fight ends, bare in mind that his hp in phase 1 is dependant on how much corruption he has, so phase 1 will go faster each time.
It's worth noting that as his corruption level decreases, the ratio of hostile : friendly adds changes; as his corruption level decreases you will have more friendly adds, so for example the boss has 75 corruption, you might get 18 hostile adds and 6 friendly ones, but if the boss has 25 this will be opposite.
Pop bloodlust at the start of this encounter entirely because there is no other time to use it, and you may as well get to the phase change faster.
This fight is mostly about positioning, it's not a real heal/dps check and is certainly not a difficult encounter, a nice way to start the raid, a nice simple boss.
