Vaporighu

Vaporighus are native to the plane of Gehenna. In all respects they are petty, sadistic, and voracious. The only force that motivates them is the gnawing pain of hunger that they can never satiate.

A vaporighu is a hideous, bloated, waddling blob of hairy flesh, vaguely humanoid in shape. Its skin is the color of gangrenous rot and drips with poisonous slime. Long, tangled, and matted fur hangs in shaggy layers from its forearms, back, belly, and stumplike legs, and its head is topped with a pair of small horns. Where its mottled skin is visible, veins of pulsing bile can be seen just beneath the surface. Its breath comes and goes in enormous, wheezing gurgles, punctuated by an occasional explosion of mucus. A vaporighu reeks of all the decay and sulphurous stench of Gehenna.

Vaporighus seem to perform no specific function in Gehenna other than to waylay whatever is unfortunate enough to cross their paths. They often pick out likely hiding places near portals or the rare watering holes in Gehenna and wait for victims to approach.

Vaporighus speak Abyssal and Infernal, but they usually do not communicate.

Vaporighus are tenacious opponents. They fight without subtlety or art, and they fight to the death.

Corrosive Slime (Ex): Vaporighus constantly exude a mucuslike slime that contains a corrosive substance. A vaporighu’s slam attack leaves behind a smear of slime. An opponent’s armor and clothing dissolve and become useless immediately unless they succeed at Reflex saves (DC 18). Any weapon that strikes a vaporighu also dissolves immediately unless it succeeds at a Reflex save (DC 18). Both DCs are Constitution based.

Fear (Su): Anyone (except other vaporighus) who sees a vaporighu within 30 feet must make a Will saving throw (DC 15) or become frightened for 2d4 rounds. An opponent who succeeds at the saving throw is immune to that vaporighu’s fear aura for 24 hours. This is a mind-affecting fear effect.

Improved Uncanny Dodge (Ex): Because of its unusual talent for detecting prey, a vaporighu retains its Dexterity bonus to AC (if any) even when flat-footed, and it cannot be flanked.

Poison Breath (Ex): Once every 1d4 rounds, a vaporighu can exhale poison breath as a standard action. This creates a 15-foot cone of toxic and corrosive green vapor. Every creature in the area takes 1d10 points of acid damage (no saving throw). The vapor is poisonous (Fortitude save DC 18). The primary damage is paralysis (3d6 rounds); the secondary damage is 3d6 Con. The vapor lingers for 2d6 rounds, dealing acid damage and requiring a new saving throw each round a creature remains within it or touches it. Vaporighus are immune to their own poison breath and to that of others of their kind.

Spell-Like Abilities: At will⁠—​animate objects, deep slumber, fly, light, mislead, produce flame. Caster level 10th; save DC 10 + spell level.

Summon Night Hag (Sp): Once per day, a vaporighu can summon one night hag. This ability functions like a summon monster VII spell (caster level 10th).
