Combat

Nagas favor spells over other forms of combat. Because they are almost always found in the lairs they guard and know well, they can arrange most encounters to suit their wishes.

Spirit nagas meet foes boldly so as to use their gaze attacks to best effect. They quickly slither forward to bite foes that avert their eyes.

Poison (Ex): Bite, Fortitude save (DC 18); initial and secondary damage 1d8 temporary Constitution.

Charming Gaze (Su): As charm person, 30 feet, Will save (DC 17).

Spells: Spirit nagas cast spells as 7th-level sorcerers, and can also cast cleric spells and spells from the domains of Chaos and Evil as arcane spells.
