Greater Nightmare

20 feet. The nightmare continually exhales black smoke. Creatures within the aura are Concealed to those outside it, and creatures outside the aura are concealed to creatures within it. Nightmares and their riders can see through this smoke. A creature that begins its turn in the area must succeed at a DC 28 fortitude save or be Sickened 2. It's then temporarily immune to being sickened by the smoke for 1 minute. This is an inhaled poison, and the nightmare and its rider are immune to it.

The nightmare Strides or Flies up to triple its Speed. Its hooves burst with intense flame, dealing 6d6 fire damage with a DC 30 reflex save to each creature other than the nightmare's rider that the nightmare moves adjacent to during its gallop. Each creature can be affected only once during a single use of Flaming Gallop.

Large or smaller, hoof, DC 30 reflex The monster Strides up to double its Speed and can move through the spaces of creatures of the listed size, Trampling each creature whose space it enters.
