Behemoth, Thunder

Thunder behemoths walk the land as little more than roving appetites, driven by an all-consuming hunger to devour every animal, plant, and even building in sight. They indiscriminately gorge their five seemingly bottomless stomachs on forests and jungles, collapse mine and mountain alike in search of ore, and raze settlements and strongholds for the cowering morsels within.

Thunder behemoths are sent out by the gods to destroy wicked cities, raze great temples or monuments that offend divine eyes, and otherwise act as instruments of divine wrath either on the surface of a world or just below it. The days before a thunder behemoth arrives are fraught with minor but unnerving earthquakes, mass exoduses of burrowing animals to the surface, and an unexplained increase in fallen trees and sinkholes.

Mighty Roar — Every 1d4 rounds as a standard action, a thunder behemoth can issue a mighty roar in a 60-foot cone that duplicates the effect of an empowered greater shout (Fortitude DC 30 for half damage). This is a sonic effect. The save DC is Constitution-based.

Rock Spitting — A thunder behemoth can spit rocks from the essentially inexhaustible store in its gizzard. It can spit up to four rocks as a standard action, with a range increment of 60 feet. A creature that is critically hit by one of these rocks must make a DC 38 Fortitude save to resist being stunned for 1 round. The save DC is Strength-based.

ruinous

Swallow Whole — A thunder behemoth has five stomachs and can shunt a swallowed victim into any one of them (usually choosing an empty stomach).
