Warlock Green Fire Quest - Codex of Xerrath - Final Boss

***Something I found out after is if you use the Pit Lord’s charge stun the boss takes 100% increased damage. Use it on cooldown as long as you have it up to stop Cataclysm and the fight is easier at lower gear levels*** This was done on live servers with 496 ilvl raid gear, day of patch release. Final boss in the quest line, very tough fight. Quest starts from a random drop off rare spawns in the Isle of Thunder.
