From Destinypedia, the Destiny wiki
Ugroth will spawn in the center of the Observatory after Mukor has taken damage, after which they will very slowly pursue the player while firing their Taken Rotting Surge. Both Ogres have immense amounts of health; there will be several Scorch Cannons located around the Observatory, and ideally all of them should be used on Mukor and Ugroth rather than the lesser Taken that will spawn in periodically. Although both Ogres move very slowly, it is highly recommended to keep track of both Ogres at all times so as to avoid getting cornered.
