Heretical Knights

Heretical Knights are the Pit of Heresy enemies that carry the Void charges, or orbs, needed to progress.

In the Tunnels of Despair, each Knight drops a Void orb. Three orbs deposited at the vessels by the three ogre-guarded doors open the next stage. The tunnels are also patrolled by Harrowing Pariahs, which are invulnerable and do not drop orbs, so players avoid them by moving through small side caves.

In the Chamber of Suffering, Knights again drop orbs, which are deposited in the container beside the blocked door. A stacking debuff builds over time, and each deposit removes stacks only from the player who makes it.
