Viscidus Viscidus is an optional boss in the Temple of Ahn ' Qiraj , a giant slime that can be accessed after the death of Fankriss the Unyielding . This boss requires a high Nature Resistance as it uses AoE poison bolts which have direct damage along with DoTs . He resets if taken outside his room , much like the bosses in Zul ' Gurub . If you are about to wipe , run outside the room and you may be able to save your life . Abilities . The Three Frost Stages . Viscidus must be slowed by Frost attacks in order to defeat him . Frostbolt , Frost Shock , and Icy Touch count toward this objective . The strength of the Frost attack doesn ' t matter , only the number of hits , so use the fastest Frost abilities possible . ( Rank 1 Frostbolt and fast Frost wands ) Frost attacks are required , but other attacks too , freezing is faster if more people is attacking it . The Three Melee Stages . Once Viscidus is frozen he must be shattered . This needs to happen very quickly or he will thaw out and continue attacking the raid . Melee attacks are required , but other attacks too , Viscidus only explodes when there ' s enough damage being done . Strategy . Ideally , all raid should drink a NR potion 2 minutes before starting , so the cooldown fades . Then , refresh NR potion on every chance . Aim for enough dps to kill your assigned Glob , and then balance stamina with NR equipment . Low stats due to wearing green NR armor may not be the best to stand NR damage . If your raid uses CT _ RaidAssist , the raid leader can check the NR resistance , and the number of NR potions on each member . Once you master the encounter , you may try drinking a pot only when you are low on hp . Beware of the single bolt : it announces the landing point of a toxin cloud , which drains health real fast . There is an addon called Viscidus Raid Warning to whisper people suffering Toxin Cloud . Viscidus is vulnerable to Frost ( spells / abilities and Frost damage ) , therefore mages are at a premium for this fight . Warlocks equipped with a Frost damage wand , i . e . Wand of Biting Cold ( usually 1 . 5 sec ) will be nearly as effective as a mage ( 1 sec casting on rank 1 frostbolt with improved frostbolt still faces the 1 . 5 sec global cooldown ) . The raid is required to get as many frost attacks into Viscidus as possible so that he will go through his several emotes and freeze . After he is frozen , a number of melee attacks must be done to shatter him into 20 or so small blobs . The raid must then kill these blobs in order to reduce Viscidus ' health . The triggering for his normal state into frozen seems to be a hitcounter of ~ 200 Frost based attacks / spells / abilities . The triggering for him to shatter once frozen seems to be a hitcounter of ~ 75 ( in 1 . 12 ) melee hits , regardless of damage . All stages have a 15 second time - limit , so if you fail to reach the next stage after that he reverts to his previous one . Time is of the essence . Once people start dying , the fight goes down hill . Killing Viscidus should take around 4 freezing phases to accomplish . Therefore , longevity is the key along with poison cleansing abilities . Mages and Druids are key to this encounter . Shamans make the fight relatively easier for the Horde because of the Poison Cleansing Totems . There might be changes in 1 . 11 or future patches allowing weapons with + X - Y frost damage to count as ( part of ) the number of attacks needed . This would mean that Hurricane and other weapons would be very useful . Alternatively , just cheese the globs with mass Goblin Sapper Charges in the middle of the room , 1 phase should be enough to take it to 15 - 30 % . Melee positioning . Most guilds keep their melee players away from Viscidus so that they don ' t take poison damage . They have to stay at least 100 yards away to avoid damage . This can be accomplished either by standing on the staircase outside Viscidus ' room or by standing inside Viscidus ' room far off to one side . The difficulty with this strat is that meleers will take one or two poison volleys while running in and out , and someone has to be in range to depoison them . However , with proper depoisoning , meleers takes much less damage and may not even need to wear full NR . The alternative is to have high - NR melee players in melee range of Viscidus , DPSing him at all times . This does a minimal amount of damage to Viscidus , but it does hurt him a bit . The advantage is that , with players moving around less , it is far easier to keep in range of shaman totems and of your Druids for depoison . The tradeoff is that you take more direct Poison damage ( which is resistible ) , but hopefully you take less DoT damage ( not resistible ) . You can also make use of Frost Oil to help freeze Viscidus . Viscidus at 80 . Assuming you made it this far , youve got a decent setup . You are still required to freeze Viscidus to defeat him . With a small group of level 80s you are likely going to get him to 1 % HP before you kill him , and completely bypass the shatter phase . It seems this fight no longer requires X number of frost attacks in a certain number of seconds , more of an overall number it seems . In my personal raid setup I had 2 Deathknights , and 1 Shaman , spamming Icy Touch and Frost Shock . The fight took just over 5 minutes . And progressed just as the above strategy says it will , minus the shatter phase . It took a long time before the first " Viscidus is starting to freeze " emote , so dont get discouraged . Keep at it ! Demigod or even old God ? Chemist Fuely suggests that oozes may be connected to the Old Gods , and that an Old ( or Demi ) god could be Viscidus . Nonetheless , it ' s currently the most powerful ooze ever known .
