Felmyst Felmyst is a fel dragon and the third boss of the Sunwell Plateau raid . She is raised from the corpse of the blue dragon Madrigosa when the blood of the slain pit lord Brutallus seeps into the ground and flows beneath her body . Felmyst is the final boss encounter before reaching Agamath , the First Gate . Felmyst drops the last of the 8 tier 6 tokens . Strategy . Even though the majority of raidwide damage Felmyst does is nature based the resistance that will help you most ( and one you should use at least while learning ) is Arcane . The incoming Nature damage is low and predictable . The Encapsulate damage ( which is Arcane based ) is rapid , random and affected by normal resistance rules . For that reason , during the learning , everyone should use their Violet Badge and plenty of Major Arcane Protection Potion . Separate your raid into three groups , each comprised of no more than 10 people ( so as to benefit from Mass - Dispel ) . The most common tactic is keeping a melee group directly behind Felmyst , and ranged groups on either side . There is no tail swipe , nor cone - breath , but she does cleave , so make sure no - one but the tank is in front of her . The Corrosion ability cannot be resisted and must be healed through . During that time the tank should also watch his own HP very closely , and stop attacking if his health ever drops under 50 % - to avoid getting killed by Parry hasten . Everyone should stay a little apart to spread out quickly if anyone nearby gets the Encapsulate , but not too spread out so they can receive Mass Dispel to negate Gas Nova . The Noxious Fumes , like most aura - type spells , should simply be healed through . During this phase Felmyst still can - and should - be attacked . For the first few seconds , while she ' s taking off your main tank can keep building aggro . Once she is in the air , only ranged attacks are possible - so all ranged DPS should be ready to use Soulshatter , Invisibility , Feign Death or any other aggro - dropping ability as soon as Felmyst lands again , if they are above the tank . Hand of Protection may also be used , provided that the ranged DPS character will be below 130 % of the main - tank ' s threat , once it expires . Felmyst will use her first aerial - ability roughly 5 seconds after leaving melee range ; the Demonic Vapor . She will target a random player for a couple seconds , then cast it under them . The spell follows that player for about ten seconds , leaving the DoT trail and summoning skeletons soon after . Stepping in the trail is not only lethal but will also summon more skeletons , which will likely overwhelm and wipe the raid . Best way to counter this ability is spreading out until second use - and starting to kite the beam away as soon as it ' s used . The safe spot for tanking skeletons and moving during Deep Breaths should be assigned - and until second Demonic Vapor starts no - one should move near it . The area around huge crate directly south from the dead tree is a good place for that . The adds spawned by the Vapor are perfectly tankable by a protection paladin . Slowing effects like the hunters ' Frost Trap are recommended in either case . This spell is cast twice , with the second cast right after the first ends . Following the two Demonic Vapor attacks , Felmyst emotes a raid warning and flies over the stage casting her Fog of Corruption attack , covering a third of the stage with a lime - green cloud . Anyone caught in the cloud will be mind - controlled until they are killed . If your raid group tanks Felmyst on an edge of the stage , the cloud can be avoided easily while you continue clearing the skeleton waves . After three breaths Felmyst will land and return to the Ground Phase . Rinse and Repeat . You have 10 minutes . A well - geared group can down the boss before a third flight phase . At level 80 - 85 . Ideal Raid Composition : 4 healers ( 2 priests ) , 2 tanks , 19 dps At level 80 , Felmyst is still a technical fight and is the biggest hurdle a raid attempting Sunwell Plateau will face . The easiest way to deal with this fight is to burn Felmyst down ( preferably to 1 % ) during phase 1 , properly deal with phase 2 , and finish her off when she lands again ( phase 1 ) . If your raid group has very high dps output , it is possible to kill Felmyst before she takes off the ground ( phase 2 ) . Below is a breakdown of each phase . Preparation : Before the fight , clarify each of the three " safe " zones where people should run during Phase 2 . The safe zones are behind the tree , in the middle ( where the ground slopes down ) and all the way down by the river that is on fire . Assign a spotter to call out where she will breathe in Phase 2 . Phase 1 ( ground phase ) is for the most part a tank and spank with a few noteworthy exceptions : Phase 2 ( flight phase ) begins 60 seconds after phase 1 ( ground phase ) . During this phase Felmyst flies around and casts two abilities : " Notes : Any raid member who is killed after being mind controlled by Felmyst ' s Fog of Corruption will not take any durability damage and should not worry about a big repair cost if the raid has wiped this way multiple times . " At 85 , burning Felmyst should go much quicker than at 80 , ensuring dispels and people dodging the fog , the fight should go quickly .
