Part I: The Last Stand of the Zandalari
Jin'rokh the Breaker: Video Guide
Stand in the water to DPS/heal. When he charges the water with electricity, get out of it. If you have Focused Lightning following you, get out of the water. Healer cooldowns on Lightning Storm. Tank swap each time the current tank gets Static Wound.
Horridon: Video Guide
Pull Horridon so his side is to the first gate on the left. Kill the adds at that gate, then repeat the process at each of the 3 next gates. Add kill priority: Dinomancers --> Elites --> Regular mobs. Also, don't stand in anything on the ground. At the last gate, War God Jalak spawns and Horridon enrages. Kill War God Jalak then Horridon. Throughout the fight, avoid Horridon's front and back AOEs. If he charges on you, run to the tank. Tanks switch off between Adds and Horridon at each different gate. The add-tank for the last gate will need to pic up War God Jalak. Have healing cooldowns ready for when Jalak is up.
Council of Elders: Video Guide
Bloodlust/Heroism shortly after pull and burn down Sul. Tank swap Malakk at 10 stacks of Frigid Assault. Healers use big CDs at the beginning of the fight because it gets progressively easier. Dispel those caught inside sand traps.
Part II: Forgotten Depths
Tortos: Video Guide
DPS priority: AOE cave bats, single target spinning Whirl Turtles, kill Tortos. Kick the dead Whirl Turtle's empty shell at the boss to interrupt Furious Stone Breath. Tortos takes 25% increased damage for 20 seconds after being hit with a turtle shell. MT on Cave Bats and OT on Tortos. Bats need to be taunted and hurt a lot and healers need to keep the tank topped off or bats will life drain. Healer CDs on Quake Stomp. Avoid falling stalactites.
Megaera: Video Guide
Tank pulls the green head and the other tank gets the blue head. DPS on green head. When green head dies, that tank go to red head. Rotate DPS and Tanking heads Green --> Blue --> Red over and over until Megaera's body dies. Healer CDs on Rampage after each head dies. Save mana for the end of the fight. Dispell Cinders. If you have Ice Beam or Cinders, run away from the group. DPS don't stand in front of heads' breath. No one stand in ice or fire on the ground.
Ji-Kun: Video Guide
Before the fight, choose 3 DPS and 1 Healer to fly from nest to nest. Each time a nest gets a red pillar of light, fly to it and kill the eggs in the nest. Everyone else, stay on the main platform. Spread out 8 yards apart to avoid being hit by someone else's Caw. Stand on green slime pools before they take up the entire arena. Healer CDs on Quills. All run to the middle using speed boost cooldowns on Down Draft. Tank swap at two stacks of Talon Rake.
Part III: Halls of the Flesh-Shaper
Durumu the Forgotten: Video Guide
Tank swap at 5 stacks of Serious Wound. DPS and Healers run away from the raid to drop off Lingering Gaze purple puddles. Don't stand in them. Run out of Force of Will (purple smoke cone on the ground). If you get fixated by red or blue beams of light, run around the room until you reveal a Fog monster. DPS down Fog monsters. When Disintegration Beam starts to case, stop what you're doing and run to where there are purple wriggling worms on the ground. Don't stand in purple/black smoke. Follow the maze through the smoke. It always starts where the wriggling worms are. There's one path at melee, and one at ranged. Run in front of someone with Life Drain on them to break it.
Tanks kite the boss slowly around the outside circle of the room. Tank swap at 7 stacks of Malformed Blood. DPS kill bloods and stand in Mutagenic Pools to gain buffs. After 10 buffs, you turn into a Saurok and can do full dps to the boss. Heroism/Bloodlust when most DPS are Sauroks. Healers also absorb Mutagenic Pool buffs. Don't dispel unless someone has more harmful than helpful buffs. No one stand in purple Volatile Pools.
Dark Animus: Video Guide
Stack at the entrance to the room. AOE Small golems then spread far out to kill Large then Massive golems. Don't get hit by Crimson Wake moving fire circles. Healers use all mana and CDs when large and massive golems are activated. DPS Bloodlust/Heroism when Large and Massive golems are up. When all the golems are dead, the boss is easy. Tanks round up half of the adds each for the trash phase, and for the boss have one tank on the boss and the other tank popping Anima Ring bubbles so the boss-tank can run through the gap. When Dark Animus is activated healers don't cast before Interrupting Jolt - wait until after or use instant casts only.
