Breath Weapon (Ex)

Every 1d4 rounds as a swift action, a thunder beast can exhale a cloud of poisonous gas in a 20-foot cone. Living creatures in the area must succeed on a DC 18 Fortitude save or sickened every round they remain in the area and for one round after leaving the area. The save DC is Constitution-based. The cloud lasts 1d4 rounds before dispersing. A strong wind (21+ mph) disperses the cloud in 1 round.


Environment The Abyss
Organization herd (5-20; 50% noncombatant young)
Treasure none

Thunder beasts are herd animals that spend their time roaming the uncountable layers of the Abyss sustaining themselves on a diet of rotted plants, minor demons, and other inconsequential life forms.

If angry or frightened, a thunder beast bellows with a low, rumbling tone. If the object of their concern does not immediately withdraw, they then breathe their foul breath and attack with their vicious bite.

A typical thunder beast is about 20 feet long. It is yellow-brown, ochre, or olive in color, mottled dark brown or black.
