Ascendant Lord Obsidius is the last boss of Blackrock Caverns in World of Warcraft: Cataclysm.

For his unyielding devotion and penchant for cruelty, the powerful shaman Dessirik the Depraved was gifted with ascension: a dark ritual that infused him with elemental powers, transforming him into a monstrosity known as Ascendant Lord Obsidius.[1]

Strategy

When you first arrive in the area Ascendant Lord Obsidius will be surrounded by many assistants—all but two (heroic: three) of whom will be eliminated when Raz makes his final appearance. The remaining assistants will aggro the player who most recently attacked them, and when they get close to their target, will channel a debuff (while on the run!) that reduces the effectiveness of healing.

Assign a DPS party member, preferably one with multiple instant ranged attacks (or AoE snares) to kite the assistants around, keeping them off the tank, for the duration of the fight. The assistants do not deal much damage, so this role is reasonably safe for a even a cloth-wearer. On heroic, Obsidius will periodically use Thunderclap; the kiter should therefore stay well away from the boss to avoid getting snared himself.

Twice during the fight, everything will stop for a moment while Ascendant Lord Obsidius changes bodies into one of his assistants. The new Ascendant Lord Obsidius will grow back to his former enlarged state, and everyone will need to switch targets and resume kiting/DPS. Tank threat is transferred; however, the kiter will need to pick up the assistant left in place of Obsidius.

Obsidius will cast Twilight Corruption, dealing 24000/48000 damage over 12 seconds on a random player; this magic DoT debuff should be dispelled.
