User:SC2Hayasui/Yogg-Saron, Master of the Legion

Yogg-Saron rises again, his undying essence possessing the imprisoned body of Sargeras. He is the Master of the Burning Legion.

Background
Long has it been said of the Shath'Yar, the Old Gods, that they are beyond life and death. They are outside the cycle of mortality, and even if destroyed their eternal power will continue to endure, a spooling corruption upon the land, growing and festering in the darkness until they are able to reconstitute themselves. Never before in the history of the cosmos has this phenomenon been demonstrated more horrifically than with the Old God Yogg-Saron. Slain in Ulduar, his undying essence polluted the Titan stronghold, until his demented worshipers channeled it into the body of Sargeras, the imprisoned dark titan.

With the devastating invasion of the Legion finally repelled on Azeroth's core and their core itself Etheric Amnion still seething, brave and powerful heroes take the battle to the Legion itself. On the central structure of the World's Heart, the Master of the Legion waits, clad in the nearly indestructible body of Sargeras, Yogg-Saron rises again, his every step a calamity, his every breath a blight upon the world. The resurrected fiend means to kill the world soul of Azeroth and destroying it. Gathering his strength from the Twisting Nether itself, Yogg-Saron bolsters in power by the minute, threatening the very existence of the Twisting Nether. Everything is bearing down on the shoulders of those who seek to eliminate the source of the Legion. Should justice prevail, all of those who fell to the mighty Legion, including the countless planets consumed in the Legion's wake, will finally be avenged and their souls finally at rest. However, if Yogg-Saron is victorious, then everything that has been fought for by all heroes from all times, will be in vain. Doing so will vanquish the Demon Lord once and for all. There will be no turning back or second chances.

Overview
Yogg-Saron is confronted upon the Etheric Amnion, the central structure of the World's Heart that contains the World Soul itself. The corruption of the Void has spread across the structure of the Etheric Amnion, but the World Soul within still shines bright, still resisting the demonic pollution of the Old Gods. The outer edges of the combat area writhe with corruption, making it dangerous to stray far from the safe, central area.

The Corruption
The Etheric Amnion is seething with the corruption of Yogg-Saron. The outer edge of the area is completely overtaken with the demonic flames of the Old God, and stepping into the corruption deals massive periodic damage. Throughout the combat, Yogg-Saron will call for Void-born monsters to manifest from the corruption and attack the heroes.

Phase Two
When the three Unbroken Ones have been slain, the Portals of Madness will become accessible to the heroes, who must now use them to enter the Realm of Madness.

The Screaming Soul of Yogg-Saron
Within the Realm of Madness, the Screaming Soul of Yogg-Saron is visible, a spectral representation of the Old God's true form.



Phase Three
When the Screaming Soul of Yogg-Saron is reduced to 40% health, it will shatter the Realm of Madness, removing all heroes from the realm safely and spawning alongside Yogg-Saron's physical form. Yogg-Saron will permanently lose the abilities Eldritch Barrier and Call the Corruption. The Screaming Soul will manifest in the center of the area, knocking away any targets that come into close contact with it.

Intermission - The Call of Yogg-Saron
This phase begins when Yogg-Saron's health is reduced to 10%. Yogg-Saron will be transported into the central area and the Screaming Soul will rise above him, and no longer knock back anyone nearby. The Screaming Soul will envelop them both in an Eldritch Barrier. Yogg-Saron will not act directly. The Eldritch Barrier protecting Yogg-Saron must be removed and his health reduced to 0% to end the phase.

Final Phase
With Yogg-Saron's physical form destroyed, his spirit has become untethered to reality and is collapsing it upon itself, threatening to drag the heroes into oblivion. Yogg-Saron's undying essence must be purged from existence once and for all.



Strategy
In Phase One, the heroes must endure Yogg-Saron's assault and reduce his health to 85%, at which point he will use Feldoom Barrier to make himself invulnerable and spawn three Unbroken Ones. Yogg-Saron must be managed while the three Unbroken Ones are dealt with. The outer edge of the area is infested with Yogg-Saron's corruption, making it a lethal hazard that must be avoided. Yogg-Saron will periodically use Call the Corruption to summon a small army of monsters from the corruption.

Once all three Unbroken Ones have been slain, Phase Two begins. The heroes can now use the Portals of Madness to enter the Realm of Madness. The heroes must split their forces in two, with one group remaining to manage Yogg-Saron and the creatures he summons, while the other group enters the Realm of Madness to engage the Screaming Soul of Yogg-Saron. Heroes in the Realm of Madness must use Titanic Energy to remove the Screaming Soul's immunity barrier, at which point the Screaming Soul will begin casting Descent into Madness. The heroes must inflict as much damage as they can before retreating from the Realm of Madness to avoid being destroyed by Descent into Madness. Once the Screaming Soul completes its cast, Yogg-Saron will be restored to 100% health, lose his Eldritch Barrier, and the fight will begin again from Phase One. The heroes must repeat the battle until the health of the Screaming Soul has been reduced to 40%.

Once the Screaming Soul is at 40%, Phase Three begins. The Screaming Soul and Yogg-Saron will appear together, and both their abilities must be managed simultaneously. The Screaming Soul will be invulnerable during this phase, and will knockback any heroes that approach it in melee, forcing the heroes to engage Yogg-Saron in the outer edge of the area, making keeping out of the corruption more difficult. Heroes must use the Titanic Energy that spawns to keep the area clear of danger. As Yogg-Saron's health is reduced, both he and the Screaming Soul will gain more abilities.

When Yogg-Saron's health has been reduced to 10%, the Intermission Phase will begin. Yogg-Saron will be brought to the center of the area with the Screaming Soul hovering above him. Neither enemy is vulnerable to damage, and the Screaming Soul will no longer knock back anyone nearby. Similar to the portion of the encounter in the Realm of Madness, heroes must gather Titanic Energy and use it to break the barrier protecting Yogg-Saron. With the barrier broken, Yogg-Saron's final 10% health must be reduced to 0 to move to the Final Phase of the encounter.

In the Final Phase, the Screaming Soul is the primary target. It's 40% health must be reduced to 0 to end the encounter. The Screaming Soul will use several of its abilities from Phase Three, as well as employing Yogg-Saron's Call the Corruption ability to spawn additional monsters.
