Asps never shirk from battle, and fight with cunning and strategy.
Poison (Ex): Bite or weapon, Fort save (DC 14); initial and secondary damage 1d6 temporary Con.
While most nagas produce venom (except the constrictors), only those with severe mutations have an effect natural bite attack to deliver it. A naga can use a full-round action (provoking attacks of opportunity from threatening foes) to apply a single dose of its natural poison to its weapon, running no risk of poisoning itself. Alternatively, a naga who has a hold on an opponent in a grapple can bite the opponent with a successful grapple check. This bite does no damage but allows the poison to do its work.
Telepathy (Ex): Nagas are all part of a communal consciousness they call the Akasha. This shared consciousness facilitates communication between nagas near and far, and contains the memories of their entire species. A group of nagas within 30 feet of each other are in constant communication. If one is aware of a particular danger, they all are. If one in a group is not flat-footed, none of them are. No naga in a group is considered flanked unless all are.
Taint Immunity (Ex): All nagas are immune to the Shadowlands Taint. They can still be harmed by effects such as the cloud of Taint spell, but they can never have a Taint score.
Alternate Form (Su): A female naga can transform her serpent tail into humanlike legs, as if using the polymorph self spell. Her size becomes Medium-size (regardless of her original size), and her speed becomes 30 feet (and she loses any swim speed she may have possessed). Changing form in this manner is a full-round action.
These creatures are scaly and usually cold-blooded. The reptilian subtype is only used to describe a set of humanoid races, not all animals and monsters that are truly reptiles.
