Dark bishop

Dark Bishops are Hexen's equivalent of the Disciples of D'Sparil from Heretic. Dark Bishops are far more dangerous than the disciples, however. Dark Bishops can move around fast, leaving afterimages of themselves behind, and shoot homing fireballs that move in an awkward rotation pattern. When a Dark Bishop is killed, it will hurt the player if they are too close to the explosion radius of the Dark Bishop that is dying.

The Heresiarch also summons them to aid it in battle.
