At the beginning of the fight, Skolas will be virtually immune to all weapons. The players must hunt down special translucent Servitors found in the arena and kill them, which will grant a 20-second period during which Skolas may be damaged. Once Skolas's health has been reduced to 70%, the servitor bonds will break and he will become permanently vulnerable. Killing any remaining Servitors after this point will have no effect. A second set of mines will appear when Skolas has been reduced to 15% health. After this set is dismantled and Skolas is killed, the encounter will be completed.
