Combining Rogue exiles, Delirium, Tormented Souls, Essences

This really is a no brainer. Maybe essences needs explanation.

Rogue exiles traped in essences. As rogue exiles fixed set of enemies, they can be hooked up to the many essence types, with a more clear visual feedback so we can even ditch the big plate with lots of unneccesearly repeated words above the enemy head, and also make the actual contained enemies more interesting as they would be a clear showcase of the essence.
Delirium ofcourse would spawn upon breaking the essence covering a decent area in delirium spawning monsters of madness fueled by the Rogue exile as it carries this delirium fog around the head which is the origin. Tormented souls spawn continously infecting normal map enemies turning them deliriuos, furthure fueling the rogue exile now free from that icy prision ready to do what it was stoped by an different exile who felt Piety over them and imprisioned instead of killed, not knowing that imprisionment just caused the poor rogue exile to descent into madness creating this delirium as a pure tormented soul at that point.
