A player known as The Legend Himself on YouTube, who also goes by sc Slayerage on Reddit and Twitch, has conquered one of the hardest boss battles in Destiny: The Taken King's raid, King's Fall.
Together with another player (EPICOOKIEZ), Slayerage managed to top a boss fight designed for six well-equipped players. I've personally participated in this battle myself and it's no joke, even with a full Fireteam in the raid.
Playing as a Titan Defender, Slayerage used Weapons of Light, combined with the new Black Spindle Exotic to inflict massive damage. Meanwhile, his teammate used a Nightstalker tether.
Together, they had to manage a swarm of thralls and exploding thralls while switching Golgoroth's gaze.
According to the post on reddit, the duo had been trying the fight for around two hours, with many close kills, before they finally succeeded. Other Fireteams might spend the entire night in the raid without managing to get Golgoroth down to half health.
That's just how good these players are.
