Fox Fey have the unique ability to change into a spirit form. The most experienced Fox Fey have developed the ability to change from their humanoid form, into a large, 9 tailed fox spirit. 

 Spirit Form: As an action, the Fox Fey can change their shape from their humanoid form to their spirit form. The Fox Fey’s spirit form appears as an ethereal fox. While in this form, the Fox Fey retains their hit points, ability scores, AC, and the ability to cast spells. At the 10th level, the Fox Fey gains the ability to change into a 9 tailed fox spirit rather than a seemingly normal fox. The Fox Fey can transition back to their humanoid form as a bonus action. While in their spirit form, Fox Fey cannot use any items they may have equipped, or in their inventory.

• Fox Spirit: Before the 10th level, the Fox Fey has the following traits changed, and gains the following abilities, when they transition into their spirit form.

• You are classified as a small fey. 
• Your movement speed is 45 feet. 
• You have 120 feet of darkvision. 
• You can communicate with other beings telepathically.
• You can use the Dash and Dodge actions as bonus actions. 
• You can use the Bite ability as an action.  

• Bite: + 2 to hit, reach of 5 feet, one creature. 1d4 Piercing damage + your Dexterity modifier upon a successful attack. 

• 9 Tailed Fox Spirit: At the 10th level, the Fox Fey has the following traits changed, and gains the following abilities, when they transition into their spirit form.  

• You are classified as a large fey.
• Your movement speed is 60 feet. 
• You have 120 feet of darkvision. 
• You can communicate with others telepathically. 
• You gain the trait Frightful Presence.  

• Frightful Presence: Each creature of the Fox Fey’s choice that is within 120 feet of the Fox Fey and aware of it must succeed on a DC 14 Wisdom saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the Fox Fey’s Frightful Presence for the next 24 hours. 

• You can use the Bite ability as an action. 

• Bite: + 7 to hit, reach of 5 feet, one creature. 3d6 Piercing damage + your Dexterity modifier upon a successful attack.  

Your Charisma score increases by 2. Your Intelligence score increases by 1. 

Fox Fey seem to be ageless. It is unknown if they are born, or if they are created. The oldest Fox Fey recorded was said to be over 700 years old. 

Fox Fey range from under 5 to over 6 feet tall and have slender builds. Your size is Medium.

Your base walking speed is 30 feet.

Accustomed to twilit forests and the night sky, you have superior vision in dark and dim conditions. You can see in dim light within 75 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern color in darkness, only shades of gray.

You have advantage on saving throws against being charmed, and magic can’t put you to sleep.

Fox Fey don’t need to sleep. Instead, they meditate deeply, remaining semiconscious, for 4 hours a day. (The Common word for such meditation is “trance.”) While meditating, you can dream after a fashion; such dreams are actually mental exercises that have become reflexive through years of practice. After resting in this way, you gain the same benefit that a human does from 8 hours of sleep.

You can speak, read, and write Common and Elvish. Elvish is fluid, with subtle intonations and intricate grammar. Elven literature is rich and varied, and their songs and poems are famous among other races. Many bards learn their language so they can add Elvish ballads to their repertoires.
