Hell hounds are rusty red to red brown in color. Their eyes are glowing red. Teeth and tongues are sooty black.

Hell hounds are not normally from the material plane, but some few now dwell on it, having been brought along by various creatures who wished their evil service.

Hell hounds move with great stealth, so they surprise opponents on a die roll of 1-4 (out of 6).

They have keen hearing, and they are surprised on a die roll of 1 only (out of 6).

Their exceptional sight allows them to locate hidden or invisible creatures 50% of the time. For these reasons they are favored as watchdogs by monsters and fire giants.

In addition to a normal attack (simply biting with their great black teeth), hell hounds breathe out a scorching fire on an opponent up to a 1" distance, causing 1 hit point of damage for each hit die they possess, unless the opponent is able to save versus [...] Breath, in which case only one-half damage is inflicted, i.e. a 7 hit dice hell hound breathes for 7 or 4 hit points of damage/attack.
