Ultimate Ability. Serath lets her dark side take over for the ultimate dutation. At that time, one stack of Burn and one stack of Weakness is applied to enemies around her. A Burn stack does Ability Damage over 3 seconds. Weakness will cause Enemy Damage to be lower than normal for 3 seconds.
Any enemies she hits with another ability during the entire ability Duration will also apply a stack of Burn and Weakness to them. Burning enemies take additional Basic Damage if Serath hits them with a Basic Attack while this ability is active.
