Adventure Guide

Uldir's titanic watcher was gifted with tenacity and an insatiable desire to discover a "solution" to the Old Gods. Her protocols have remained fully intact, even though many other systems in her facility have collapsed. WARNING: M.O.T.H.E.R. will not accept aid from contaminated subjects.


Overview of tactics for the MOTHER fight.

Pass through Defense Grids to reach the final chamber of the Hall of Sanitation. Reaching the third and final chamber cleanses the raid of all corruption, and inflicts MOTHER with Depleted Energy. When MOTHER is first active in any chamber she will begin a countdown to activate Cleansing Purge within that chamber.

Alliance Brann Bronzebeard yells: Well that explains why the blood trolls are lurkin' about, but why would the titans keep an Old God alive?

Alliance Brann Bronzebeard yells: Sounds like a plan. While we're at it, I'll see what other secrets the titans may have left behind.
