Halion, the Twilight Destroyer

[Holyssa]

There aren't many movies out yet about the latest raid boss, nor is he immediately available as of this post. But for those that haven't looked at the PTR, Wowwiki has a general rundown of how the fight works:

Minibosses:

Saviana Ragefire: Will Periodically enrage, AoEing the raid until it is Tranq Shot'd off. Tank & spank.

Baltharus the Warborn: Uses Blast Wave frequently, and will split himself into copies which need to be offtanked. Mark the 'main' boss, and burn him down so the clones go poof.

General Zarithrian: An AoE fear, much like a warrior's Intimidating Shout. He'll also summon adds that use interruptable AoE abilities.

Halion has three phases, in which the raid must switch between the physical realm and the shadow realm.

Phase 1

A few seconds after being engaged, Halion summons a wall of flame in a circle around him, closing off any players not in the stage.

Halion has a frontal cone breath attack. Like most dragon bosses, he has a tail swipe and cleave. He also summons fireballs, which fall from the sky and hit a large area with fire damage, leaving a patch of flame where it hit, as well as four flames going in four directions out of the fire patch. The location where the fireball will hit is indicated by a hellfire graphic. Any player under it must move out before the fireball hits. All players must move away from the flames that spread from the patch.

He also puts a debuff on random players called Mark of Consumption. When the debuff ends or when it is removed, a patch forms under the player's feet that deals damage to players in it and players will be pushed away from the patch. Players afflicted have to move to the edge of the stage then get the debuff removed, before running back to the raid. The size of the patch depends on how long it took to dispel it.

This phase ends when halion reaches 75%.

Phase 2

Halion shifts to the shadow realm, and summons a portal which players can use to enter as well. In the shadow realm, Halion still has his breath and Mark of Consumption, but they do shadow damage instead of fire damage, and the Mark of Consumption's knockback is now a pull instead.

Also, two shadow orbs circle around the edges of the stage. Every once in a while, a death beam will come out of the two, connecting them and dealing enough damage to instantly kill any player in the beam. The players (including the tank) must rotate to avoid damage by the death beam.

This phase ends at 50%.

Phase 3

Halion exists in both realms, and the raid must split into two; one fights him in the twilight realm, which should consist mostly of melee, and the other fights him in the physical realm, which should consist mostly of ranged. This is because it is easier for melee to navigate in the twilight realm without fireballs making them have to go to ranged, and ranged have an easier time navigating in the physical realm where there are no death beams which require them to stop DPS to keep moving and not get hit.

The other change is that during this phase, Halion recieves a buff called Corporeality. This is determined by a percentage shown at the top of the screen which begins at 50%. Depending on the value of this, Halion will take and deal more damage in one realm and deal and take less damage in the other. There are no damage differences to either realm whilst it remains at 50%.

Damaging Halion in the Physical realm will cause him to phase further into the Twilight realm, lowering his corporeality and works vise versa when damaged in the Twilight Realm. If no damage is dealt in one realm, Halion will begin to rapidly regenerate health.

*Corporeality < 50% - Halion does and takes more damage in the Twilight Realm. He does and takes less damage in the physical one.

*Corporeality = 50% - Halion does and takes normal damage in both realms.

*Corporeality > 50% - Halion does and takes more damage in the Physical Realm. He does and takes less damage in the twilight one.

Halion's corporeality should be kept between 40% and 60%.
