Heroic: Omnotron Defense System
Defeat the Omnotron Defense System in Blackwing Descent on Heroic Difficulty.
Defeat the Omnotron Defense System on Heroic Difficulty in Blackwing Descent to earn this 10-point achievement.
Manage Nefarian's ability modifications
During the fight, Nefarian will periodically modify the Omnotron bosses' abilities. When Magmatron is affected, the player marked with Acquiring Target will be rooted; move away from the flamethrower as a raid. When Electron is modified, the lightning rod becomes an AoE hitting the entire raid with reduced damage closer to the affected target. When Arcanotron is modified, a power generator transforms into a bomb that expands and detonates across roughly a fourth of the room. When Toxitron is modified, the raid warps to the center of an existing chemical cloud, which risks a wipe if poison bombs are present in or near the cloud.
Defeat the Omnotron Defense System
Defeat all four bosses—Magmatron, Electron, Arcanotron, and Toxitron—while managing Nefarian's ability modifications throughout the encounter.
