Dikast

'''Dikast, Oppressive Mind''' is a Vex Cyclops boss first seen in Season of the Splicer. It was the final boss of Expunge: Styx, governing the Styx domain and keeping the Endless Night running through its subroutines.

After the Guardian destroyed it the first time, Bungie revived it through Quria, Blade Transform. In Expunge: Corrupted Styx it returned as Dikast, Oppressive Mind Reborn and was finally defeated.

At half health it raises an immunity shield and summons laser walls. Players must insert the Authentication Key into an installation on the far side of the room to drop the shield. The corrupted version can also summon Taken alongside Vex.
