Nalfeshnee

From Planescape: Monstrous Compendium Appendix I (1994):

Few beings terrify mortals more than the nalfeshnee. Mortals who pass into the Abyss eventually come before one of these “lords of woe”, there to suffer judgment and the pain of transformation.

Nalfeshnee are 20’ tall; most of their immense strength goes simply to support their bodies. They combine the worst features of ape and boar, and their small wings appear unable to bear their ponderous bodies. Nalfeshnee have red, glowing eyes that pierce the mind and seem to draw energy from just a glance.

Nalfeshnee can communicate with any being using a powerful form of telepathy.

Nalfeshnee are the most intelligent tanar’ri, considering themselves superior even to the balors. Nalfeshnee do not act on this feeling because they recognize the balors’ greater strength. However, a nalfeshnee seldom passes up an opportunity to secretly embarrass a balor, foil its plans, or even prolong the Blood War. The nalfeshnee rule the 400th layer of the Abyss, where they sit on flaming thrones on the Mountain of Woe. There they judge the mortal life forces that pass into the Abyss.

Nalfeshnee feed on hatred and despair, emotions they can draw out of any being they see. They devour these feelings from the life forces they judge, leaving empty husks of useless thoughts. These husks then transform into other forms of tanar’ri in ceremonies involving unimaginable torture.

Combat: Nalfeshnee are never surprised. They are immune to weapons of less than +2 enchantment, but can be hit by weapons of cold-wrought iron.

Though the nalfeshnee usually sit atop their thrones and judge the masses of mortal lives in the Abyss, they are capable in battle. They can attack with two claws (1d4 damage each) and bite (2d4 damage), but prefer a special attack that looks like the color spray spell (usable three times per day). They must concentrate for an entire melee round; hits on the creature during that round do not break concentration. Then the nalfeshnee releases multiple rainbow beams that shoot in every direction. All creatures within 60’ suffer 15 hp damage (save vs. spell for half damage). They must then again save vs. spell with -2 penalty. Failure means they are temporarily stricken dumb and wander in a trance for 1d10 rounds. In that trance each creature a vision of its greatest fear.

In addition to the standard abilities of all tanar’ri, nalfeshnee have the following spell-like powers: alter self, bind, call lightning, chill touch, detect invisibility (always active), distance distortion, ESP (always active), feeblemind, forget, giant insect, invisibility, know alignment (always active), mirror image, protection from good (always active), raise dead, slow, and web. Nalfeshnee can also attempt to gate in 1-6 babaus or 1 vrock, twice per day, with a 50% chance of success.

From Dungeons & Dragons Monster Manual (2014):

The nalfeshnee is one of the most grotesque demons — a corpulent mockery of ape and boar standing twice the height of a human, with feathered wings that seem too small for its bloated body. These brutish features conceal a remarkable intelligence and cunning.

Nalfeshnees are devastating in combat, using their wings to soar above the front ranks and reach vulnerable adversaries that can be dispatched with little effort. From the thick of battle, they telepathically bellow commands to lesser demons, even as they inspire a sense of dread that forces their foes to scatter and run.

Nalfeshnees feed on hatred and despair, but they crave humanoid flesh above all else. They keep their larders filled with humanoids abducted from the Material Plane, then eat those creatures alive during elaborate feasts. Thinking of themselves as refined and cultured, nalfeshnees employ stained and rusted cutlery when they dine.
