Kitsune age differently than most other mortal creatures. Instead of the usual 4 stages of adult life (adult, middle age, old, venerable), kitsune life stages are measured by how many tails they have. At adulthood, they gain their first tail, and every 100 years later they grow a new tail. Typically the live anywhere from 900 to 1,200 years old.

You are a Fey.

You are small in Fox Form, Medium in Human and Hybrid Form.

A kitsune's base speed is 40 feet.

Thanks to your vulpine ancestry you are granted improved vision, unlike those around you. You can see in dim light within 60 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 gain some spells only kitsune can cast.

A kitsune’s true form is that of a small fox, but it is most often encountered by mortals in its Hybrid form. The kitsune's HP remains the same throughout its different forms. A kitsune remains in one form until it chooses to assume a new one(cost:1BA). A change in form cannot be dispelled, nor does a kitsune revert to its natural form when killed. A true seeing spell, however, reveals its natural form if it is in humanoid or hybrid form.

• Fox Form: In fox form the kitsune is Tiny size. It takes a -4 size penalty to its Strength score, but gains a +4 size bonus to their Dexterity score and has a bite attack appropriate for its size.
• Humanoid Form: The humanoid form is unique to every kitsune; a kitsune in this form always assumes the same appearance and traits, much as a lycanthrope would.
• Hybrid Form: In hybrid form a kitsune passes for a Medium size humanoid at first glance, but a Investigation check (DC 10) reveals the creature’s fangs, ears, and tails. The kitsune has a bite attack in this form, and can also wield weapons or wear armor.

Each kitsune is born with a mask, which grows with them as they age. The mask itself is a physical manifestation of the kitsune's soul, similar to a familiar. They need not wear the mask, but if it is ever destroyed or worn by another creature the link is severed and the kitsune gains disadvantages to all saving throws (costs a tail to recover mask). When worn, the mask provides the kitsune with a +1 bonus to saves made against charisma and wisdom saving throws. 

Kitsune age differently than most other mortal creatures. Instead of the usual 4 stages of adult life (adult, middle age, old, venerable), kitsune life stages are measured by how many tails they have. At adulthood, they gain their first tail, and every 100 years later they grow a new tail. Every new tail grants a +1 racial bonus to either Intelligence, Wisdom, Charisma. This bonus cannot exceed +6. Kitsune do not suffer aging penalties, nor do they gain any other benefit from aging.

Tails

For a player using this race, You can also grant tails at certain Level milestones to show their growth from early to end game. For exampe I may recoment giving a tail out ever two levels after 3rd level.

So a player at 15th level would have a total of seven tails.

A kitsune character has a +2 racial bonus on wisdom and perception checks.

Common, Sylvan, and one of your choice.

You are immune to being charmed, and seeing through illusions, and have advantages on checks to notice when an individual is being charmed or controlled.

As a kitsune you have some resistance to fire.

You have a +1 Proficiency Bonus cause of your vast wisdom
