Sacred Nagaji
Source Pathfinder Lost Omens Impossible Lands
You stand out from most nagaji, with the upper body of a beautiful human and the lower body of a green or white snake. Legends claim your ancestors were faithful snakes uplifted by Nalinivati rather than nagaji created by the goddess. Instead of a fangs unarmed attack, you have a tail attack that deals 1d6 bludgeoning damage, is in the brawling weapon group, and has the finesse and unarmed traits. You gain a +2 circumstance bonus to your Fortitude or Reflex DC against attempts to Grapple or Trip you. This bonus also applies to saving throws against effects that would Grab you, Restrain you, or knock you Prone.
