The Fight:

This is a three phase fight, and is the most difficult, yet challenging and not rng fight you'll face yet.

Phase 1 (100-80%):

First off, this is a 2 tank fight, but the 2nd tank is not needed at all until the 3rd phase.   Therefore, it's opted to use that OT for...

Mutated Transformation, clicking on the potions on his table turns you into this abomination.   You'll be dealing 2K per tick in 10 man to everyone in the raid, and it is disease cleansable.   But don't cleanse it because it has the following abilities:

• Eat Ooze, which consumes the various slime pools that are dropped 
• Regurgitate Ooze, which will slow targets by 50%, will be key to kiting things
• Mutated Slash, which increases physical damage taken by 4% for 20 sec stacks to 5

These abilties are key to the fight and should be done in almost that priority listed.

Putricide will drop 2 Puddle of Slime around.   They will grow with time.    The only way to eliminate them is for the Abom to eat them up.   Which conseqently gives them the "energy" they need to perform, Regurgitated Ooze to snare adds, if you're doing it normal non-achievement kills.   A key to this is not to simply eat up every slime you see and clean the room.   You must conserve 1 or 2 so the Abom can readily have energy available for the moves to perform.     Must balance between cleaning new puddles, keeping existing puddles small and managable.

Mutated Slash, is just an extra ability, costs no energy that you can use if there's nothing else going on.  It'll help increase dps if you have time for it.

Putricide will summon an add, "Unstable Experiment" and it alternates between the Volatile Ooze and Gas Cloud.   In his room, you'll see 2 big vats on the walls, one green on the right (north), one orange on the left (south).    The Volatile Ooze will spawn from the green one, the Gas Clouds will spawn from the orange one.

Volatile Ooze, a few seconds after spawning, they will fixate on someone.  A big giant green beam will connect with his target.  That target will be rooted, and when the ooze reaches him, it does a knockback explosion (not death), in which damage is split among all it hits.    Then it will pick a new target to fixate on and repeat.    The goal is to have the dps, including and especially melee kill it asap.    The Abom is to snare it so there'd be more time.   The DPS are to try to stay away until it fixates, but maybe nudge closer to get there faster when it does.   You'll likely fail the first fixates at current gear/dps levels, try to kill it before the 2nd fixate it does.  This will be the biggest source of damage in this phase until you have the dps to out zerg it, or luck of position to have enough time for it.

Gas Cloud, will also fixate on someone.   Except this time, the target will gain a 10 stack debuff of Gaseous Bloat.   A stack of it falls off every 2 seconds.  Should the Gas Cloud reach its target, it will aoe with each melee hit it does, with damage based on the number of stacks.   Basically 10 stack is around  25K damage to the entire raid.    Goal is to kite it and kill it.   Abom again slows it down, and dps don't be near it til it fixates on someone.

Anyways, as for tank positioning, we now use the tanking on Green Side strat.   Every time a Volatile Ooze spawns, everyone (mostly) stacks up on it and zerg it down.   If it explodes, the damage is split with all of us so it's minimal, just have to reach and kill before 2nd explosions.   Also gives us minimal running time for max dps time on Putricide himself.   We'd also be on the far side of Gas Clouds giving good kite distance.  

At 80%, he will cast Tear Gas, which stuns everything in the room, also making us immune to damage so the various pools won't kill anyone.    It also resets any snares and fixate targets the Ooze or Cloud may have.   Prepare to re-snare it, or time your pushovers when there's no adds up.

Phase 2 (80-35%):

It's the same abilties as above, with 2 new things.

Choking Gas Bomb, small orange beakers he drops around him.    They not only hurt, but also like Archavon's cloud, reduces your hit by 75%.   They also explode after 20 seconds.    Tank is to kite Putricide away from them, and of course the raid don't stand near them.

Malleable Goo, are ooze shadow crashes again.   They explode in an area and also slows down all that hit.   Watch for flying oozes, don't stand under them.

Tear Gas stun occurs yet again for the transition into the next phase, so again time it well...

Phase 3 (35-0%):

Adds no longer spawn, you also lose the Abom ability, P2 abilties remain, and it's where the OT comes into play.    Quickly finish off the remaining ooze/cloud if one remains.

First off, without the Abom, that mean existing and new slime pools will grow indefinitely making a soft enrage similar to Vashj.    As the room will eventually be covered, killing us all.   There's also a hard enrage too at 10 mins, so maybe you won't actually see soft enrage happening.    Still, it forces you to kite in a gradually shrinking room.

Anyways, the new abilty that he has for the OT is Mutated Plague.   What it does is puts a debuff on the tank, which makes him aoe everyone around him (think Burning Bile).   Each stack, doubles its damage, so like 200 -> 400 -> 800 -> 1600 -> etc.    Should the stack fall off, Putricide heals for 300K (500K in other modes) per stack.    So the goal is to never let the stack fall off, but yet manage it so no single one tank gets high in stacks to make the damage spike up exponentially.

A guide to this with 2 tanks is to do it like this...   MT tanks it to 3 stacks.   OT takes over and takes it to 3 stacks.    MT comes back in and takes over before his debuff falls off and tanks it to 5 stacks (that's 2 extra stacks).    OT comes back and tanks over to 5 stacks as well.   Hope you kill it by then.

In 25 man, it was designed to have 3 tanks.   You can do something similar to above, or alternate per stack (taunt after each new stack), making the kill with 3 stacks per tank.

Find what works best for your raid.   That's about it for normal mode, a fairly fun and challenging fight.    Good luck with your attempts!
