WoW Cataclysm - Cho'gall Boss Guide

Under Cho'gall's control, the orcish Twilight's Hammer clan was transformed into a murderous cult obsessed with the Old Gods and their herald, Deathwing. Extended contact with his dark master has hideously warped both Cho'gall's mind and body.

Once a promising member of the Shadow Council, Cho'gall's thirst for power and forbidden knowledge led him to embrace the maddening whispers of the Old Gods. His body, twisted and malformed, now reflects the corruption that has taken root in his very soul. Cho'gall's dual heads, each with its own twisted personality, embody the chaotic nature of his masters. One head is calculating and manipulative, while the other is utterly deranged, driven by a manic devotion to the dark forces he serves.

The transformation of the Twilight's Hammer clan under Cho'gall was swift and brutal. What was once a group of disenfranchised orcs became a fanatical sect, willing to commit unspeakable atrocities in the name of their dark gods. Rituals of blood and shadow became commonplace as Cho'gall sought to usher in the return of the Old Gods to Azeroth.

Cho'gall's influence extends beyond his immediate followers. His mastery of dark magic and his connection to the Old Gods have made him a significant threat to all of Azeroth. Heroes from across the land have tried to stop him, only to find themselves ensnared in his intricate web of deceit and terror. His ultimate goal is to bring about an age of chaos and destruction, paving the way for the Old Gods to reclaim their dominion over the world.

Cho'gall's Abilities Breakdown

Corrupted Blood Mechanics:

Exposure to several of Cho'gall's abilities increases a player's Corruption level. For each point of Corruption, players suffer 2% additional damage from Cho'gall's Corruption of the Old God ability.

- Corruption - Accelerated: At 25% Corruption, players gain Corruption: Accelerated, which rapidly increases their Corruption level.

-  Corruption - Sickness: At 50% Corruption, players periodically become violently ill, vomiting and dealing 19500-20500 Shadow damage in a 20-degree cone in front of them, increasing Corruption for those hit.

-  Corruption - Malformation: At 75% Corruption, a tentacle Malformation erupts from the player's back, casting Shadow Bolts at allies for 24375-25625 Shadow damage.

-  Corruption - Absolute: At 100% Corruption, players fully transform into faceless horrors, becoming unhealable but dealing 100% additional damage and casting spells instantly.
