The Prophet Tharon'ja

The Prophet Tharon'ja is the last boss of Drak'Tharon Keep. He is a large skeletal wind serpent much like the Avatar of Hakkar. The Prophet Tharon'ja is known for ripping the flesh from the bones of some of the most formidable ice troll warriors. From the upper tiers of the fortress, Tharon'ja watches as waves of undead trolls pour from the keep's corridors to bolster the Scourge ranks in their assault on Zul'Drak.

 * Decay Flesh: Burns an enemy, removing flesh from the target.


 * Return Flesh: Returns the flesh to the target.


 * Curse of Life: Deals shadow damage every 3 seconds for 9 seconds. The effect is removed if the target falls below 50% of their maximum life and can be decursed.


 * Eye Beam: Channeled ability dealing 1040 to 1160 Nature (Heroic: 2080 to 2320) damage every 2 sec for 5 seconds.

Tactics
He begins the fight as a skeletal serpent with a few abilities:
 * Shadowbolt (2000 damage)
 * Curse of Life (Drains 50% of the enemy's health.)

At certain intervals he uses Decay Flesh, which drains party members' health and turns Tharon'ja into a mortal Windserpent while turning the players into undead skeletons. When in this form, the skeleton players have four spells, in order of how they show up on the bar.
 * Slaying Strike: Instant cast, 8 yard range, requires melee weapon, inflicts about normal weapon damage.1 sec cooldown.
 * Taunt: Instant cast, 10 yard range, taunts the creature, increasing the chance that it will attack the caster.
 * Bone Armor: Instant cast, encases the caster in bone armor, absorbing 4163 to 4837 damage for 10 sec. While the armor holds, spellcasting cannot be interrupted by physical attacks. 10 second cooldown.
 * Touch of Life: Instant cast, 20 yard range, steals 1900 to 2100 life from target enemy. 5 second cooldown.

Tanks should use Bone Armor on cooldown and spam Taunt. Everyone else should spam Slaying Strike.

When in mortal Windserpent form, Tharon'ja will occasionally cast a ground-targeted AoE, which does 800 to 900 Nature damage per tick to any player standing in the area. It can be avoided by simply moving around and out of that area.

After a certain percentage of damage is done in this form, everyone switches back. Tharon'ja's switch to mortal Windserpent form and back to skeletal form are both aggro wipes. .

Alternate Strategy: This fight can be done with two or more hunters. The pets will continue to attack even during the skeletal phase, which will nuke the boss down in seconds. Be sure to rotate taunts between party members. Each time the skeletal phase is about to begin and as soon as it ends, cast Mend Pet (and/or Lick Your Wounds if specced). Any pet class can do this - Hunters, Warlocks, or Unholy Death Knights. All pets avoid the Decay Flesh debuff and continue to attack.

Trivia
Tharon'ja shares the same voice actor as Volkhan. Who this is, however, is a mystery.

Speculation
By his title "The Prophet," and his wind serpent form, he may be another transformed Drakkari leader who killed a Loa god for his power prior to being corrupted by the Scourge.
