These creatures range widely in size. They are not particularly aggressive, but will often lash out with a bite attack before attempting to retreat.
Viper snakes rely on their venomous bite to kill prey and defend themselves.
Poison (Ex): A viper snake has a poisonous bite that deals initial and secondary damage of 1d6 Con. The save DC varies by the snake’s size, with the Huge Viper's Save DC being 14. The save DCs are Constitution-based.
