- ω ϖ—Inflicts 5,363 to 5,637 damage every second and reduces move speed by 25% for 5 seconds.
- ω ϖ—Raining Green Ooze. Deals 5,363 to 5,637 Nature damage to enemies in cone every second for 5 seconds.
- ω ϖ—Inflicts 3,900 to 4,100 shadow damage every second and reduces healing received by 50% (Heroic: 75%) for 12 seconds. After the Infection is removed, a small ooze is created at the target's location.
An ooze spawns when Mutated Infection is removed from a player (either by being dispelled or expiring). These merge into a Big Ooze and eventually explode.
- ω ϖ—Inflicts 2,925 to 3,075 damage every second and reduces move speed by 50%.
- ω ϖ 10 yd range—Inflicts 3,413 to 3,587 damage to enemies every 2 seconds, and also causes the Little Ooze to merge with other nearby Ooze.
These result when any two Oozes merge.
- ω ϖ—Inflicts 2,925 to 3,075 damage every second and reduces move speed by 50%.
- ω ϖ 10 yd range—Inflicts 4,388 to 4,612 damage to enemies every 2 seconds, it will also cause the Big Ooze to merge with other nearby Ooze.
- ω ϖ 10 yd range—Inflicts 9,750 to 10,250 damage to enemies. This is caused by the Big Ooze merging with other oozes 5 times.
This fight has only one phase. One tank should keep Rotface in the center of the room. A second tank (or other seasoned kiter) needs to kite the big Oozes in a wide circle along the outer wall. The raid stands behind Rotface.
It's a good idea to mark the kiting tank, but raidmarks may be moved at random by some boss mods. If possible, use an with an , or some other non-combat pet that follows its owner closely (usually a floating/flying pet, for example wouldn't be particularly useful for that purpose).
It's frequently recommended to use the DPS cooldowns at 30%. This is not a useful recommendation, since the encounter mechanics remain the same over the whole fight - there is no special enrage at low boss health. The only thing which changes is the Mutated Infection rate, the time between Infections slowly decreases. For this reason, it's best to use all cooldowns just a few seconds after the pull, as soon as everybody is in position. At that point, all damage dealers can maximize their output undisturbed from Infections or small Oozes. It's even possible to have the kiting tank help DPSing until the second Infection.
In regular intervals, Rotface uses Slime Spray. He turns in a random direction (this ability is not targeted on specific players) and sprays slime in a frontal cone, all raiders must quickly move behind him. It's easier to dodge this ability if everyone stands rather close to him (including ranged). Slime spray has a long range, so it can hit a Mutated Infection victims while they are dealing with their Ooze, in which case they need quick healing.
Some groups do not move for the Slime Sprays. This increases DPS time and makes it easier to track the off tank's position.
Mutated Infection and OozesEdit
Dealing with these two elements is the key to this fight. In decreasing intervals, a random raid member gets Mutated Infection. This debuff ticks for some damage for 12 seconds, and then spawns a small Ooze with 500k aggro on the formerly infected player. Whenever any two Oozes get within 10 yards of each other, they automatically combine. The result of such a combine is as follos:
- Two small Oozes merge into a Big Ooze (size 1)
- A small and a Big Ooze merge into a Big Ooze with size one larger than the initial one
- Two Big Oozes merge into a Big Ooze with size one larger than the smaller of the two initial ones.
- A Big Ooze of size 5 explodes (see below)
Big Oozes deal high melee damage, move at half speed and have a normal aggro table—thus they can be kited.
All players should follow these tips:
- keep track of the ooze kiter at all times, be aware where to run when getting infected.
- Upon infection, run ahead of the ooze kiter and wait for the Small Ooze to spawn.
- Some raids cleanse the infectee, 5 seconds after they become infected, but this may decrease the time to the next infection.
- When running to the kiter, avoid ooze patches and flooded room quarters. Meet the kiter ahead of such obstacles.
- As soon as the Small Ooze spawns, snare it or slow it down, so the Big Ooze catches up.
- Run with the kiter until the merge emote is displayed (e.g. "Big Ooze can barely maintain its form").
- The very first Infectee needs to kite or snare the ooze until a second small ooze spawns and merges with it.
Because the intervals between Mutated Infections decrease, over time the number of oozes and slime patches increases, to the point where they get out of control and the raid wipes (=soft enrage). Kiting and merging Oozes is complicated by Professer Putricide randomly flooding a quarter of the room with poison slime. It's possible to run through short distances of poison slime by jumping, but it's a better idea to keep an eye on the pipes leading into the room and avoid the quarter which gets flooded next.
Whenever a Big Ooze has absorbed five other Oozes, Rotface emotes, and four seconds later the Big Ooze explodes. This deals heavy AoE damage around the Ooze, and additionally rains small globules of slime at random raiders. The targeting of these small globules takes place once the casting of Unstable Ooze Explosion completes, so everyone must wait to move until the cast is complete.
A major problem in this encounter are accidental merges of Small Oozes while another Big Ooze is already up. This leads to a "loose" Big Ooze, which usually aggros a healer, heads straight into the raid and kills everyone with its aura. Players trailed by Small Oozes must take care to avoid this. In the later stages of the fight, when Mutated Infections happen faster, accidental merges may happen nonetheless. The Ooze kiter must be aware of this possibility and quickly taunt surplus Big Oozes. Some raids pre-designate a second kiter who takes care of extra Big Oozes.
The healers' focus should be on the raid and on Mutated Infection targets in particular. 1/2 (10/25 player) healers are enough to keep the tank up. All other healers must watch over the raid. Mutated Infection targets may be unable to avoid Slime Spray and/or may be forced to run through poison slime.
It may help to have one person call out what is happening. DPS/Healers can be told when to switch sides, and people with the slime debuff can be alerted. Situational awareness is required from every raid member.
- Death knights are arguably the best choice for an ooze kiting tank, due to their many long-range threat generation abilities. Chains of Ice are invaluable for snaring the little oozes in position to be engulfed by the big ooze.
- Mages should avoid using Mirror Image: this may confuse the little oozes' aggro table, causing them to stop chasing the mage and aggro on a healer. Slow can be cast on the oozes to help the designated kiter if they are having problems.
- Paladins should be prepared to cast Hand of Freedom on the offtank, should he need to run through the ooze flood.
- Shadow Priests can use Dispersion to run through the big ooze, merging their own ooze in the process.
- Warlocks can use Shadow Ward to slightly diminish the damage from ticking Mutated Infection, thus easing the healers job.
During the heroic version of Rotface, Professor Putricide comes to the balcony and casts Vile Gas on random players. If enough players stand away from Rotface, Vile Gas is never cast on the melee group. Analogous to Rotgut, 8 players at range seem to be enough (in 25 player). It's important that Vile Gas soakers don't move into melee range when avoiding the ooze flood.
Mutated Infection — The Mutated Infection inflicts 3,900 to 4,100 shadow damage every second and reduces healing received by 75% instead of 50%. This increases the healing required by infection victims by a lot.
Ooze Flood - The Ooze Flood inflicts 5363 to 5637 damage every 1 sec and reduces move speed by 10%, stacking up to 10 times, for 5 sec. This means players (including the ooze kiter) cannot spend too much time in Ooze Floods or they eventually get rooted.
