Innate Spellcasting. The näkki's innate spellcasting ability is Charisma (spell save DC 14). The näkki can innately cast the following spells, requiring no material components:
Amphibious. The näkki can breathe air and water.
Fey Charm. The näkki targets one humanoid or beast that she can see within 30 feet of her. If the target can see the näkki, it must succeed on a DC 14 Wisdom saving throw or be magically charmed. The charmed creature regards the näkki as a trusted friend to be heeded and protected. Although the target isn't under the näkki's control, it takes the näkki's requests or actions in the most favorable way it can. Each time the näkki or her allies do anything harmful to the target, it can repeat the saving throw, ending the effect on itself on a success. Otherwise, the effect lasts 24 hours or until the näkki dies, is on a different plane of existence from the target or ends the effect as a bonus action. If a target's saving throw is successful, the target is immune to the näkki's Fey Charm for the next 24 hours. The näkki can have no more than one humanoid and up to three beasts charmed at a time.
