Garrosh, son of Grommash Hellscream, first learned of his father's heroism when Thrall encountered the young orc in Outland. The seeds of pride were planted. Garrosh spearheaded Horde victories in Northrend and, as Warchief, consolidated Horde power amidst the chaos of the Cataclysm. But his visions of orc supremacy by any means have brought the armies of the world crashing down upon Orgrimmar... a final reckoning that Garrosh himself awaits with brutal relish.

• Overview - At the beginning of the encounter Garrosh calls Kor'kron Warbringers and Far Seers to assault the players alongside him. Siege Engineers periodically join the battle and try to activate the Kor'kron Iron Stars on the sides of the room. Killing a Siege Engineer will prevent him from activating his Iron Star, but an active Iron Star will also crush any Kor'kron orcs in its path. When Garrosh reaches 10% health remaining, he will draw upon the power of Y'Shaarj to heal himself, gaining new abilities and no longer calling orc soldiers to his aid. During this phase, Garrosh will periodically pull all players into the Realm of Y'Shaarj, where they must battle their way through Sha minions to reach Garrosh and interrupt his efforts to draw more power from the heart. Every 25 energy Garrosh is allowed to gain will empower one of his abilities. Upon being reduced to 10% health a second time, Garrosh will fully drain the Heart of Y'Shaarj, granting him 100 energy and empowering all his abilities until he is defeated.
