A cauchemar nightmare is about the size of a light war horse.
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 24 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.
Carrying Capacity: A light load for a cauchemar is up to 612 pounds; a medium load, 613–1,224 pounds; and a heavy load, 1,225–1,840 pounds.
