Water Breathing (Sp): Once per day a nixie can use water breathing as the spell cast by a 6th-level sorcerer. (They usually bestow this effect on those they have charmed.)

Charm Person (Sp): A nixie can charm person three times per day as the spell cast by a 4th-level sorcerer. Those affected must succeed at a Will save (DC 15) or be charmed for 24 hours, performing heavy labor, guard duty, and other onerous tasks for the nixie community. Shortly before the effect wears off, the nixie escorts the charmed creature away and orders it to keep walking.

Skills:All sprites receive a +2 racial bonus to Search, Spot, and Listen checks. Nixies receive +2 on Listen and Spot checks and +5 racial bonus to Hide checks when in the water.

Sprites fight their opponents with spells and pint-sized weaponry. They prefer ambushes and other trickery to direct confrontation.

Nixies rely on their charm person ability to deter enemies, entering combat only to protect themselves and their territory.
