Overview

Adventure Guide says

Players attempt to turn the massive Hellfire Cannons in the Citadel's courtyard against the mighty gate of the Citadel, while fending off Siegemaster Mar'tak and her militarized force. Throughout the encounter, waves of enemies rush at the players, periodically accompanied by huge siege weapons that seek to destroy the Cannons and the players defending them. Destroying these siege weapons allows players to salvage Felfire Munitions, which may be brought to the Hellfire Cannon, allowing it to continuously fire Hellfire Rounds at the Reinforced Hellfire Door. Once players successfully breach the Reinforced Hellfire Door, Siegemaster Mar'tak's forces retreat into the Citadel.

  • Quickly defeat Gorebound Felcasters after they use Metamorphosis to become a Gorebound Terror.
  • Defeat Fel-Infused Siege Weapons to keep the Hellfire Cannons alive.
  • Be ready to grab the attention of any Hellfire Reinforcements.
  • Slam stacks increase Physical damage taken, so be wary when tanking multiple enemies and a Hulking Berserker.
