Guardian Nagas are the largest nagas, being around 20 feet in length and weighing around 500 lbs at full growth. Their serpentine bodies are patterned in green and gold with a silvery triangular pattern on the back, and their eyes are bright and intelligent, burning with an almost hypnotic inner light.

In combat, guardian nagas can wrap around a victim of man-size or smaller and constrict, inflicting damage each round; escaping from this constriction requires a roll equal to that needed to open a stuck door. They also will use their deadly venomous bite (if bitten, save vs. Poison or die). Alternately, a guardian naga can spit its venom at any target within 60 feet, and if the victim is hit they must save vs. Poison or die. If all of this weren’t enough, a guardian naga has the spell-casting abilities of a 6th-level Cleric.

Guardian nagas are not generally aggressive, and may even assist parties. They are often found guarding dangerous evil creatures or artifacts, or sometimes protecting shrines or other holy places.
