Icecrown Rotface

Source: Aliena (25-man)
Hello and welcome to the TankSpot Icecrown Citadel Raid Guide! My name is Aliena and in this video I'll cover everything you need to know about the normal mode 25-man version of the Rotface encounter that's unlocked after defeating Deathbringer Saurfang.

Rotface has 36 million health and is located in a circular chamber with pipes going all around the outsides of the room. He is pretty much a tank and spank fight with three twists to him that give him a bit of a Grobbulus-Heigan Naxxramas flavor. A setup of 2 tanks, 6-7 healers and 16-17 dps is recommended for this encounter.

To start out the fight, your main tank should run into the middle of the room and turn the boss 180 degrees with the rest of your raid staying close behind Rotface's back. Once he is turned, the raid should spread out in the area right behind and next to Rotface, ideally leaving the area right around your main tank open. This is because Rotface uses an ability called Slime Spray, which is a 1.5 second cast and then a 5 second channeled AoE nature damage spell. He will pick a random raid member to cast it on, turn towards that person and then channel Slime Spray which hits for about 7k damage per second in a frontal cone.

While he doesn't hit particularly hard, you do want to avoid that extra damage on your tank if at all possible. It's incredibly easy to predict what area is going to be affected by Slime Spray since Rotface turns before he even starts channeling. Everyone in the affected area simply needs to move out of it.

Now secondly, what I'd like to explain is the environmental twist and the reason you're all stacked up in the very middle of this large room. The room is actually split into four quarters. At any given time during this encounter, one quarter of the room is going to be covered by green slime that deals around 5k nature damage every second and reduces movement speed by 25% for 5 seconds to anyone standing in it. The slime will randomly cover all four areas one after another, but never the same one twice until all four have been covered once. That pattern repeats throughout the entire fight. It's easy to see where the next ooze flood will take place since the pipes open a little prior to that. The majority of your raid will never have to worry about this, unless they get hit with a debuff called Mutated Infection.

Mutated Infection is a disease that lasts 12 seconds, deals around 4000 damage every second and will reduce all healing received by the target by 50%. This is approximately cast every 15 seconds but seems to speed up as the fight progresses. When the debuff runs out or is cleansed, a small mutant slime baby will pop out at the affected target's feet, which is where your offtank comes into play. People that get the debuff always need to run to the Offtank, so he can pick up the slime offspring. Once two of these little slimes come together, ie. after two infections, they will merge into a big slime that hits exceptionally hard and it is advised to kite it along the outsides of the room, but keeping the ooze flood pattern in mind.

Every person that gets a debuff after the big ooze has emerged needs to move into the kiting path between the offtank and the big slime to ensure that the big slime is close enough to absorb the little one.

The big slime continues absorbing little player slimes to power himself up, and once it absorbs 5 little oozes, it will cast a spell called Unstable Ooze Explosion. This ability has a slow cast and air travel time, but basically launches around 10 missiles into the air that are aimed at random players, or rather the ground they stand on. They also deal considerable damage in a 6 yard range when they hit anyone and the damage stacks, so once you see the emote, every raid member needs to move out of the middle of the room to keep it free before the bombs land.

Once it explodes, the whole game starts over. Merge 2 slimes, power them up 5 times, move out of the middle, rinse repeat. The pace of debuffs and oozes spawning seems to pick up during the battle, so ideally you want to assign someone to dispel it when the raid member is close to your offtank so the affected person does not have to stand around the whole 12 seconds.

Key to this fight is your kiter, sufficient DPS, and relying on people with the debuff to move to the right spot at the right time without getting irritated by Ooze Flood. Good luck!

There are two major mechanics the raid needs to be aware of and react to. Every few seconds, Rotface will turn toward a random player and begin to channel a slime cone attack. To counter this, we split our raid into two groups, with each stationed behind one of Rotface’s legs. Whenever the boss turns to face a group, everyone in that pile rotates around to the other group’s position for the duration of the slime spew. When it ends, they shift back to their native position.

The other major mechanic the raid needs to be aware of is the mutated infection. This disease effect causes a moderate amount of damage, but more importantly causes a Small Ooze to spawn when removed. Small Oozes cannot be taunted, and will slowly pursue the player who they spawned from until they are destroyed. Once the player afflicted by Mutated Infection is outside of the raid, they can be cleansed safely.

When a Small Ooze contacts another ooze, the two will merge to form a Big Ooze. The Big Oozes have a normal threat table, and can be taunted.

The first player with the infection gets clear of the raid, is dispelled, and has to kite his Ooze until a second player is infected. When the second player is infected, he needs to get clear of the raid (preferably in the direction of the other kiter), be dispelled, and kite his Ooze into the other Ooze. From there, the offtank will taunt, tank, and kite the Big Ooze, while subsequent infections run out of the raid to drag their Small Oozes into the Big Ooze until it explodes. Remember: damage never has to attack anything other than Rotface himself. The Oozes will all be consumed by proper execution of the kiting.

Both sizes of Ooze will occasionally fire globs of Sticky Ooze near the player who is kiting them. These globs spawn patches of slime on the floor which reduce movement speed by 50%. They are tossed out inaccurately, and as such are fairly simple to avoid.

Periodically, Professor Putricide will flood a corner of the room with slime. The slime causes a relatively low amount of damage, and a minor snare. This is actually a fairly insignificant mechanic; the kiting tank can still outrun the Big Ooze, the damage ticks are not significant enough to be threatening, and the rest of the raid has no reason to be anywhere near the flooded areas.

Once the Big Ooze absorbs five other oozes, it will begin to explode. The whole raid will need to be aware of the explosion, as a series of ooze droplets will rain down on locations which players were standing at when the explosion occurred. All the raid has to do to counter this is move to an area no one had been standing at. Any of the corner sections that isn’t flooded by slime should be safe. When the slime has finished raining down, the raid resumes their normal positions and starts with the first Small Ooze kite again.

TANKING FOOTNOTE:
While the Big Ooze’s initial damage is still manageable, the damage dealt quickly reaches unhealable levels as other oozes are absorbed. We found the Big Ooze was best handled by taunting it free from the raid, then generating a small amount of threat by tanking the Big Ooze through a defensive cooldown for about ten seconds. From that point on, the offtank should kite the ooze around the edge of the room, being careful to keep it away from the raid as it has a point blank AE pulse.
