Explosions have a much better chance when dealing gibbing damage. This releases an explosive kamikaze Hades Sphere in the process, but you can find these independent of their hosts. They behave like anything but, though, considering that they have fast, straight fireballs and can only be permanently killed when they explode. The death incarnates are recolored revenants. They are basically Hell knights with half the health (thank goodness), can block damage, and have two different fireballs.
Demon wizards are the supreme flier, fairly durable and firing erratic waves of magic. Grells are erstwhile cacodemons, about half as healthy but toting a slowing, poisonous fireball and a bobbing flight pattern that makes them tough to hit with rockets.
The flesh spawn are faster, less durable lost souls, but they are only ever found in packs.
