Background

Former Leader of the Forest Troll Clans. Caught By the Alliance in the Second War but freed by the Horde. Because of their actions, Zul'jin decided to aide the Orcs and their efforts as long as they attempted to fight the Elves who had driven them from their homeland jungles. Zul'jin is rumoured to have become a Merchant near the end of the Troll Forests after the Second War.

He has recently arisen again, trying to gain the support of all the clans of forest trolls, to recapture what is left of Quel'thalas now that there is no great High Elf army, and the Blood Elves are weak. He can currently be found in Zul'Aman

Introduction

Zul'jin is the leader of the Forest Trolls. In the trailer for the Zul'Aman dungeon, his monologue goes as follows:

"Dis was our land. TROLL land. We Amani was here before anyone! Da' elves and dere Alliance came to drive us out. But we never give up. We never forget...

Da' elves took my eye. I cut off my own arm to escape 'dem... and now, 'de fight alongside da' HORDE!? I SPIT on da' Horde! I hate you, I hate you all... But I got a surprise for ya' now, so come on in...

De' Amani never give up! We never forget. We never die. 'Dis is our land: you wanna stay, you stay here forever! We gonna bury you here."

In the Dungeon Zul'Aman, he is the last boss to be tackled.

The Fight

This is another multi phase fight. Zul'jin changes form every 20% of his hitpoints, and with the change of form comes a threat wipe and different abilities. The threat wipe can be a pain, because he is immune to taunt, so be careful with damage over time spells. At the start of the fight, everyone should go to the platform on which Zul'jin is standing.

Phase 1

Zul'jin starts off in Troll form, dealing mainly melee damage. He will do a whirlwind, which hits everyone within melee range, and also casts Grievous Throw, which causes damage over time on the target until the target has been healed fully.

Phase 2

At the start of this phase, there will be a threat wipe and Zul'jin changes to Bear form. He also performs a debuff on the raid which should be dispelled as soon as possible on the main tank and healers. If not dispelled within 6 seconds, players will receive damage and be stunned for a further 4 seconds. Zul'jin does some fairly strong DPS in this stage.

Phase 3

The usual threat wipe, then Zul'jin takes on Eagle form. He spawns energy storms that causes players within range to take damage and be knocked back. The main downside to this stage is that casters will take 1250 damage every time they cast a spell, including healers, therefore, heal over time spells are handy here. DPS Zul'jin down as soon as possible, use bandages and casters use wands, which also saves mana for the remaining fight.

Phase 4

Another threat wipe, then Zul'jin takes on the form of the Lynx. He does not do a lot of damage in this stage, but he will "Fixate" on a player, dealing damage to them over the period of 10 seconds. Intervene is useful here to take some of this damage. After Fixate has finished, Zul'jin's attention returns to the tank. He will then perform a Whirlwind-like move, similar to Kargath Bladefist in the Shattered Halls. Health can drop quickly here so use health potions, health stones and bandages.

Phase 5

The threat wipe is accompanied with Zul'jin changing to a Drogonhawk form. He does mainly fire damage in this phase. Players will receive a debuff which increases fire damage taken. Zul'jin will place a Pillar of Fire under random players, similar to void zones, which must be avoided as they will kill anyone standing in them for a short time. Players should spread out to avoid these zones. Zul'jin also does Flame Breath which can cause extra damage due to the debuff. All melee other than the tank should stand behind Zul'jin, due to this Flame Breath.

Zul'jin has several abilities, which he uses depending on his form at the time. Below is a table showing the special abilities that are used:
