Zul'Jin: Final boss.

Abilities

Every time his health drops by 20%, he walks to the center of the platform, switches form, and does a threat wipe. Note that he's immune to Taunt, but Debuffs (and DoTs) remain on him.
[edit] Phase 1: Troll Form

* Whirlwind: AoE dealing 3k damage on plate, 6k on leather. 2s cast time.
* Grievous Throw: 1.5-3.5k initial damage on a random player. DoT deals 2.4k damage every 2s, removed if the player has 100% HP.

[edit] Phase 2: Bear Form

* Creeping Paralysis: Debuff on the entire raid. Deals 4.5k Nature damage after 5.5s, and applies the debuff Paralyzed. Paralyzed players are stunned for 4s. Both debuffs are dispellable magic effects.
* Overpower: 4.6-5.9k on the tank, ~9s cooldown.

[edit] Phase 3: Eagle Form

While in Eagle Form, he remains stationary, and doesn't attack.

* Energy Storm: Debuff on the entire raid causes every character that uses -any- ability that takes Mana to take 1250 damage.
* Feather Vortex: 4 Feather Vortex spawn, they look like tornados and move around. They deal 1k Nature damage and knock players back if they are touched.

[edit] Phase 4: Lynx Form

* Claw Rage: Zul'Jin focuses a random player other than the tank, and hits him 12 times with Claw Rage in about 6s. The first strike deals 500 damage. Every strike applies the stackable debuff Claw Rage, which increases the damage taken by consecutive attacks by 150. Thus, the second hit deals 650, the third 800, and so on. The last hit deals 2150 damage, for a total of 16k. Claw Rage attacks cannot miss, be dodged, parried, or blocked. If the focused player feigns/vanishes/etc, Zul'Jin will focus the tank.
* Lynx Hunt: When he uses this ability, he does so 9 times in a row in quick succession. Every attack targets a random player, and deals about 2k damage, further mitigated by armor. The target is chosen completely random; one player might be targeted multiple times in a row (up to 3?), and he can also target the tank. Every player that was attacked also gets the debuff Lynx Hunt, which deals 1.5k damage every 2s over 10s.

[edit] Phase 5: Dragonhawk Form

* Flame Whirl: He gains this buff, rotates for 2s, then deals 1k Fire damage to the entire raid (partially resistable). This will also apply a stackable debuff that increases Fire damage taken by x%, which cannot be resisted. 12s cooldown.
* Flame Breath: Hits everyone in front of him for 2-3k Fire damage (partially resistable). 7s cooldown.
* Flame Columns: PBAoE cast on a random player (or pet), dealing 900 Fire damage every second for 10 seconds. There may be up to 3 columns at the same time.

[edit] Strategy

Get your whole group up on his platform past the threshold when you start the fight, there's a wall of fire that closes his platform off. The 6 adds don't have many hitpoints and die fast to AoE. The adds are linked to the boss.

Every phase change he does a threat wipe, so be careful with DoTs. He's immune to Taunt, so the tank must quickly gain aggro. Use Mis-direction if possible. When he turns into an Eagle you do not need to worry about the threat list though, as explained below. He changes phases every 20% of his hitpoints. Also, raid members might want to consider changing their gear out for max, or at least more, stamina. Having the mages/priests/healers above 9k health is a lot of help in this fight.
[edit] Phase 1

Melees watch out for his whirlwind. Healers react quickly to Grievous Throw. Players only lose this DoT when their health reaches 100%.
[edit] Phase 2

As soon as he starts this phase you will notice everyone gets a Paralysis debuff. Dispel it off the main tank and yourself, then other healers if time (or the tank doesn't need a heal). DPS etc do not need it dispelled. After 5 seconds of having the debuff, you will take damage and become stunned, assign someone to top people off before the next. He can hit decently hard, so keep the tank topped. Uses overpower on the tank.

Two tactics exist to cleanse the debuff. Either have the raid stack, and use Mass Dispel to cleanse the entire raid of the debuff, or just dispel the MT and a healer or two of the debuff.
[edit] Phase 3

Stay away from the tornados that spawn and move around the room. They knock you back and deal around 1k damage. If you are a caster (yes healers included) everytime you cast you will get hit for about 1250 damage. The key thing to do in this phase is not get cornered by tornados and stay alive. Heal over time spells really make this phase much easier. Melee need to try and burn him down as quick as they can, as they get no punishment for doing damage. Use bandages. Casters use wands and regenerate mana for the next phases.
[edit] Phase 4

Lynx form he melees fairly weak on the tank. He also will use Claw Rage on a random player in the raid and melee them. Intervene near the end of the phase (9-11 stacks) to help out cloth wearers. Healers use fast spells. Announce Vanish/Divine Shield/etc to the raid, so healers know that he will change back to the tank. Healers take good care of Lynx Hunt victims, as everyone should be topped for the next Claw Rage. Everyone needs to be on their toes to stay alive, he's very fast, and your health can drop quickly. Keep Healthstones/potions ready.
[edit] Phase 5

Everyone will get a buffet like debuff every so often, increasing fire damage taken. He will choose random people throughout the raid and place a beam of fire on them. They may take lots of damage due to the debuff, so move out of these beams ASAP. It's a simple phase if people are good at staying out of void zones. Spread out so only one person is hit at the same time. Flame Breath will hit the tank for more and more fire damage due to the debuff, so DPS him down as fast as you can. The tank needs to build threat fast, but also stay focused to move out of the beams quickly. Melee stay in his back to avoid getting hit by Flame Breath.
