Sara, Avatar of Yogg-Saron, has come to bring an end to the Nexus. Empowered by Yogg-Saron, Sara has control over the whole battlefield, having the ability to manipulate enemies from afar with Tentacles who do her bidding. Using her global Brain Link and Tentacles who can spread Psychosis, Sara can spread the Old Gods' insanity out of combat, reducing the enemy's armor before a fight even breaks out. In combat, Sara's mortal form struggles a little, but she can still apply plenty of debuffs against foes to claim a victory.
Many of Sara's abilities use Chaos, a scarce resource that Sara generates little by little. To gain more Chaos, Sara needs to complete Rituals that she can choose at Level 1. Obtaining Chaos is key to letting Sara wreak havoc.
But once Sara reaches Level 10, her power grows tremendously. She may either choose to double down on her mental dominance with Malady of the Mind, or she can unleash her true form with Avatar of Yogg-Saron. Beware the latter heroic ability; if Sara is allowed to get to Level 20, perhaps Yogg-Saron himself will join the fight!
