Hengeyokai
The creatures collectively known as hengeyokai are a diverse array of sapient animal yokai, or faerie creatures. United by their common traits of base nature as a magical animal and their ability to assume a humanoid form, the most prominent of the hengeyokai are the kitsunes (foxes), bakeneko (cats), mujinas (badgers), itachi (weasels), and tanuki (raccoon dogs). Minor species of hengeyokai include kawauso (otters) and jorogumo (spiders)
For those wishing to add a more myth-accurate feel to the race, add the following optional racial trait:
Hengeyokai: You belong to a race of magical beasts that can assume partially or wholly humanoid form, as well as revert to your true bestial shape when it suits you. As an action, you can shift into any one of your three forms.
Hybrid Form is your default form. It functions as normal for a character.
In your Human Form, you gain Advantage on all Charisma (Deception) checks made to pass yourself off as human. It otherwise functions as Hybrid Form.
In your Beast Form, which is determined by your race, your game statistics are replaced by the statistics of the beast, but retaining your alignment, personality, Intelligence, Wisdom and Charisma scores. You also retain all of your skill and saving throw proficiencies, in addition to gaining those of the beast; if you and the beast have the same proficiency and the beast’s bonus is higher than yours, you use the beast’s bonus.
Changing shapes does not alter your current hit points, maximum hit points, or hit dice.
You can remain in any of these three forms as long as you wish, but must consciously choose to change shapes.
You can change shapes once at 1st level, twice at 5th level, and thrice at 11th level. You regain all expended uses of this trait when you complete a long rest.
If you have exhausted your uses of shapeshifting, you can revert back to hybrid form, but you cannot then change again into beast or human form.
