Korosek, Thronebringer

Bold text

Korosek, Thronebringer is a Hive Lightbearer Wizard Lieutenant who attempted to pull Savathûn's Throne World into the material plane from the Scarlet Keep for a Lucent invasion of Earth. They are encountered as the final boss of the PsiOps Battleground: Moon activity.

Gameplay
Korosek can be found at the end of Psi-Ops Battleground: Moon activity, after heading to the bridge section of the Scarlet Keep. The boss will immediately summon reinforcements, including Acolytes and Knights. Korosek is equipped with Arc Pulse Grenades and has the ability to Stormtrance when they have enough energy, indicated by the glow of their eyes changing from green to a bright blue along with using Darkness Blasts at any nearby player. Once they have been weakened, Imperial Optus Psions will subdue the Hive Lightbearer and teleport the fireteam into the Mindscape.

Upon entering the Mindscape, players must proceed forward and interact with the relic to begin the boss fight. Korosek will spawn, along with hordes of Hive enemies to assist them. After Korosek has lost a third of their health, they will summon an immunity shield and teleport away. Players must then pick up the Synaptic Spear and use it to defeat an Aspect of Savathûn in order to continue fighting the boss. The fireteam will have to repeat this a second time after the Thronebringer's health has been reduced by another third, when they teleport away and two aspects appear. Like before, they both must be destroyed with the spear in order to progress to the final phase of the boss fight. From here, Korosek is fully vulnerable and can be killed. Upon destroying the Ghost, which can resurrect the Wizard if left unchecked, the fireteam will return to the Scarlet Keep, where the Imperial Optuses will leave with a now fully-detained Mor'ek.
