Siege of Orgrimmar

Immerseus

• Immerseus
• Sha Puddle
• Contaminated Puddle

Immerseus begins with 100 Corruption, displayed as a visible power bar, and the objective of the encounter is to cleanse him by reducing his Corruption level to 0. Each time Immerseus is reduced to zero health, he Splits into a mix of dark Sha Puddles and watery Contaminated Puddles. Following each Split, Immerseus reforms with reduced health and Corruption depending on how successful the raid was in dealing with the two types of Puddles. This cycle repeats until Immerseus's Corruption reaches 10 or lower, at which point he is cleansed.

• Damage Dealers: When Immerseus splits, destroy the dark Sha Puddles before they reach the center and merge into Immerseus.

• He Softfoot
• Sun Tenderheart
• Embodied Misery
• Embodied Sorrow
• Embodied Gloom

Players battle the brewmaster Rook Stonetoe, the rogue He Softfoot, and the priest Sun Tenderheart, as the three Fallen Protectors assault the raid simultaneously. At 66% and 33% health remaining, each Protector performs Desperate Measures, manifesting spirits of fallen allies to bring new and powerful attacks to bear against the raid until those spirits are defeated.

• Damage Dealers: Each Protector channels [Bond of the Golden Lotus] at 1% health remaining, and will recover unless all three are defeated at once.

Norushen

• Norushen
• Amalgam of Corruption
• Manifestation of Corruption
• Essence of Corruption
• Greater Corruption

Norushen seals all players inside a Quarantine Zone and extracts a portion of each player's corruption to form an Amalgam of Corruption. The object of the encounter is to destroy this creature. Players must reduce their personal level of Corruption in order to inflict full damage to the Amalgam. Players can accomplish this by interacting with the nodes of Purifying Light that active around the room, which will pull them into another phase where they must face a role-specific challenge. Overcoming this challenge will Purify the player and allow them to inflict full damage to the Amalgam.

Sha of Pride

• Sha of Pride
• Manifestation of Pride
• Reflection

Players gain 5 Pride when hit by any ability from the Sha of Pride or its minions, though Norushen periodically protects several players at a time from this effect. The Sha of Pride's abilities trigger increasingly dangerous effects on players the more Pride they have. When the Sha of Pride reaches 30% health remaining, it destroys Norushen, who purifies the raid of their Pride with his final action. From that point, players must defeat the Sha before their Pride overwhelms them.

Players assault fortified towers as waves of Kor'kron troops rush forth to repel them, and Warlord Zaela circles overhead on her fearsome proto-drake, Galakras.

Malkorok

• Malkorok
• Living Corruption

Malkorok's platform begins covered with a dark miasma that absorbs all healing done to players, converting it into an absorption shield instead. Malkorok strikes the ground with a large cone smash three times in sequence, and then causes the same three areas struck to erupt simultaneously with dark energy. Malkorok draws in the miasma, entering a Blood Rage and empowering his melee attacks but allowing players to heal normally for a time. Malkorok then exhales the dark energy, and the cycle repeats until he is defeated.

When he detects a clump of seriously injured players, Thok enters a Blood Frenzy, during which he pursues random targets, instantly devouring any players that cross his path.
