Rotface Rotface is a boss in the Plagueworks wing of the Icecrown Citadel raid . The fight is a Battle for survival and requires good raid awareness , repositioning and some kiting . This boss has been available since January 5 , 2010 on US servers and January 6 on EU servers . Abilities . Little Ooze . 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 . Big Ooze . These result when any two Oozes merge . Setup . 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 ) . Cooldowns . 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 . Slime Spray . 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 Oozes . 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 : 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 : 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 . Problems . 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 . Heroic Mode . 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 . Quotes . Sound files .
