SQ hydra traits
A thessalgorgon can use its breath weapon once every 1d4+1 rounds to create a 60–foot cone of green gas. Those caught in the area of the gas can attempt a DC 23 Fortitude save to resist the effects, but those who fail the save are immediately petrified. This petrification is temporary—each round, a petrified creature can attempt a new DC 23 Fortitude save to recover from the petrification as long as it is not caught within the area of effect of the thessalgorgon’s breath weapon a second time while petrified. A creature exposed to the thessalgorgon’s breath a second time while already petrified becomes permanently petrified, and can no longer attempt to make additional Fortitude saves to recover naturally. The save DC is Constitution-based.
Though a thessalmonster cannot be killed by severing all of its serpentine heads, doing so prevents them from attacking and can assist in slaying its body. Any attack that is not an attempt to sever a head affects the body, including area attacks or attacks that cause piercing or bludgeoning damage. To sever a head, an opponent must make a sunder attempt with a slashing weapon targeting a head.
A head is considered a separate weapon with hardness 0 and hit points equal to the thessalmonster’s HD. To sever a head, an opponent must inflict enough damage to reduce the head’s hit points to 0 or less. Severing a head deals damage to the thessalmonster’s body equal to the thessalmonsters’s current HD. A thessalmonster can’t attack with a severed head, but takes no other penalties.

Environment temperate plains
A typical thessalgorgon stands over 12 feet tall at the shoulder and measures 24 feet from snout to tail. It weighs about 8,000 pounds.
Thessalgorgons are a cross between a gorgon and a thessalhydra. They attack intruders on sight, attempting to trample, gore, or petrify them. There is no way to calm these furious creatures, and they are impossible to domesticate.
A thessalgorgon begins combat by charging at its opponents. It then bites relentlessly with all heads until its opponents are dead or flee.
