Breath Weapon (Su): Despite its large number of mouths, a squamous spewer can only use one type of breath weapon in a given round, though it may spew it from up to three mouths simultaneously in up to three different areas. The energy type is determined randomly by rolling d% before each use: 01-25 acid, 26-50 cold, 51-75 electricity, 76-100 fire. The area of the breath weapon in any given round is either a 30-foot cone or a 60-foot line (50% chance of either). Regardless of the type of energy it uses or the area it affects, the breath weapon deals 3d6 points of damage (Reflex DC 17 half). Once a squamous spewer uses its breath weapon, it cannot use it again until 1d4 rounds have passed. Some squamous spewers may have breath weapon varieties that differ from these options - the DM can select a breath weapon possessed by another type of dragon if he or she so wishes.

Roar (Ex): Three times per day, a squamous spewer can let loose a frightening roar from its many mouths. All creatures within a 60-foot-radius spread with fewer Hit Dice than the squamous spewer become panicked if they fail a DC 19 Fortitude save. Creatures with HD equal to or greater than the squamous spewer are shaken on a failed save rather than panicked.

Amorphous (Ex): Squamous spewers are not subject to critical hits. They have no clear front or back, so they cannot be flanked.

Blindsense (Ex): A squamous spewer's extraordinary powers of scent and echolocation allow it to pinpoint the location of any living creature within 60 feet.

Dragon Traits: Despite their aberrant nature, squamous spewers share certain traits with creatures of the dragon type, including darkvision out to 60 feet, immunity to paralysis and magic sleep effects, and low-light vision.

Skills: Thanks to its multiple eyes, a squamous spewer has a +4 racial bonus on Spot checks. Its natural camouflage gives it a +4 racial bonus on Hide checks.

A squamous spewer prefers to hide from enemies until they are within range of its roar. After dispersing weaker foes, the creature uses its breath weapons until targets close within melee range (using Combat Reflexes if the opportunity presents itself).
