Pixie

The pixie has advantage on saving throws against spells and other magical effects.

The pixie's innate spellcasting ability is Charisma (spell save DC 12). It can innately cast the following spells, requiring only its pixie dust as a component:

At will: druidcraft

1/day each: confusion, dancing lights, detect evil and good, detect thoughts, dispel magic, entangle, fly, phantasmal force, polymorph, sleep

The pixie magically turns invisible until its concentration ends (as if concentrating on a spell). Any equipment the pixie wears or carries is invisible with it.
