Also Known As Hell Horse

From Wikipedia, the free encyclopedia

In Danish folklore, a helhest (Danish "Hel horse") is a three-legged horse associated with death. The horse figures into a number Danish phrases as recent as the 19th century, such as "han gaar som en helhest" ("he walks like a hel-horse") for a male who "blunders in noisily," and the helhest is sometimes described as going "around the churchyard on his three legs, he fetches Death." In Schleswig, a phrase is recorded that, in time of plague, Hell rides about on a three-legged horse, destroying men. The helhest was originally the steed of the goddess Hel.

A nightmare that is described as a mare who "destroys mercifully." The orginal Aganippe was the result of Poseidon's raping of Demeter, and she punished the evil by bestowing upon them dreams terrible to behold

A nightmare can fight while carrying a rider, but the rider cannot also fight unless he or she succeeds on a Ride check.

A nightmare's natural weapons, as well as any weapons it wields, are treated as evil-aligned for the purpose of overcoming damage reduction.


Flaming Hooves (Su): A blow from a nightmare's hooves sets combustible materials alight.

Smoke (Su): During the excitement of battle, a nightmare snorts and neighs with rage. This snorting fills a 15-foot cone with a hot, sulfurous smoke that chokes and blinds opponents. Anyone in the cone must succeed on a DC 16 Fortitude save or take a -2 penalty on all attack and damage rolls until 1d6 minutes after leaving the cone. The cone lasts 1 round, and the nightmare uses it once as a free action during its turn each round. The save DC is Constitution-based.

Because of the smoke it gives off, a nightmare has concealment against creatures 5 feet away and total concealment against creatures 10 feet or farther away. The smoke does not obscure the nightmare's vision at all.

astral projection and etherealness (Su): These abilities function just like the spells of the same names (caster level 20th); a nightmare can use either at will.

Carrying Capacity: A light load for a nightmare is up to 300 pounds; a medium load, 301-600 pounds; and a heavy load, 601-900 pounds.
