I will update this to keep it up to date with changes from both the PTR and live servers. The strategy that I post is what my guild/group used to kill the boss on PTR or live. If you have a more efficient suggestion please post to let me know.
Though once vast in number, only a few donzen twilight dragons now remain. Astride these hardened survivors are the last vestiges of the Twilight's Hammer's army: the elite drake raiders of Deathwing's personal escort. Led by the insidious Warmaster Blackhorn, they move with hunholy purpose, driven to protect their dark master.
Flying alongside the Skyfire and surveying the scene while his massive twilight drake lobs balls of destruction at the gunship, Warmaster Blackhorn gives the order for his elite dragonriders to swoop into battle.
Sky Captain Swayze helms this massive gunship equipped with numerous cannons and a pair of harpoon guns for its defense. The gunship is sturdy but not indestructible, and if it sustains too much damage the pursuit of Deathwing will come to an untimely end
Alliance engineers equipped the Skyfire with two repurposed harpoon guns, seized during its prior service in Northrend. Harpoon gunners spear the enemy's Assault Drakes and reel them in to bring them within reach of ranged attackers on the deck. The drakes strain against the line, eventually breaking free and returning to a safe distance. After a pause to reload, the harpoon gunners then spear their target anew.
Warmaster Blackhorn takes to the skies with this massive twilight drake.
Goriona unleashes a massive blast of dark energy at a random location on the deck of the Skyfire. Twilight Onslaught inflicts 800,000/2,000,000 (10/25) Shadow damage, divided evenly among all players within its 10 yard radius and the Skyfire. If the attack strikes the deck of the Skyfire without hitting a player, the gunship suffers the full damage.
Twilight Assault Drake
These drakes strafe across the deck of the ship, deposit their fierce riders onto the deck, and then retreat to a safe distance to bombard the gunship.
he twilight drakes launch bursts of dark energy at a random location on the deck of the Skyfire. Twilight Barrage inflicts 200,000/200,000 (10/25) Shadow damage, divided evenly among all players within its 5 yard radius and the Skyfire. If the attack strikes the deck of the Skyfire without hitting a player, the gunship suffers the full damage instead.
Twilight Elite Dreadblade
The Dreadblade charges at the location of a random distant player. Inflicting 100,000 Physical damage to all players in its path.
The Dreadblade carves a swath of destruction with its dark sword. The sword inflicts 400,00/800,000 Shadow damage to enemies in a frontal cone, and 3000 shadow damage every 2 seconds for 1 minutes. This effect stacks
Twilight Elite Slayer
The Slayer charges at the location of a random distant player. Inflicting 100,000 Physical damage to all players in its path.
The Slayer strikes a vicious blow with his sword. The strike inflics 150 physical damage, and 3000 physical damage every 2 seconds for 1 minute. This effect stacks.
Sleek infiltrator drakes airdrop goblins strapped with powerfule xplosives onto the deck of the ship. These sapper rush to the breach the gunship bridge and detonate their destructive payload.
Upon reaching the Skyfire's bridge, the sapper explodes. Doing 250,000/250,000 damage to all players in 8 yards, damages the skyfire for 20% of its total durability, and kills the sapper.
Once the skyfire's defenders defeat three waves of dragonriders, Warmaster Blackhorn leaps down onto the deck of the gunship.
Sunders his current target ruducing players armor by 20% for 30 seconds, stacks.
Screams fiercely inflicting 65,000 Physcial damage to all enemies within 10 yards and interrupting spell casting for 8 seconds.
Unleashes a wave of force that inflics 100,000 Physical damage to enemies in a 80 yard frontal cone, and stuns them for 4 seconds.
As Warmaster Blackhorn takes damage during the course of the fight he inflicts 1% more damage for each 1% of health he is missing.
After depositing her master on the deck of the skyfire, Goriona hovers alongside and rains destruction down on the players. Once she has suffered sufficient damage, she will break off.
Goriona launches a blast of dark energy at the location of a random player, inflicting 50,000 Shadow damage on impact to all players within an 8 yard radius. Twilight flames linger on the deck inflicting 40,000 shadow damage to players who stand in it.
