Keksis, the Betrayed

Keksis, the Betrayed is a Taken Captain that was captured and imprisoned within the Prison of Elders.

Gameplay
Like any Taken Captain, Keksis is armed with an Arc Shrapnel Launcher and can both teleport erratically and rapidly hurl Darkness Bolts that blind Guardians. However, in Challenge of the Elders, he will gain the ability to summon explosives that will temporarily suppress a Guardian's abilities if left unchecked. The explosive will be floating around in the middle of the arena, and players must stand in it and channel its Corrupted Light to avoid getting the "Suppressed" debuff.
