Your innate healing abilities let you recover from some of the grimmest wounds. During a Long Rest, you can automatically reverse Grievous Wounds. Additionally, you can reattach any severed body parts (fingers, legs, tails, and so on), which are automatically restored at the end of the Long Rest. If your severed body parts aren’t available, you can replace them with the same body parts of another creature of the same general anatomy as you. If you wish to intentionally swap out body parts with replacements, you can sever your own body parts with no pain or discomfort.

The ability to make use of unusual body parts (for example, giving yourself the taloned paw of a lion if you lose a hand) are left to the GM’s discretion. In any event, swapping a severed body part for an unusual body part grants you no mechanical Advantages not covered by other traits

As a Bonus Action, you can take the Hide action to conceal yourself without needing to be Heavily Obscured or behind Three-Quarters Cover or Total Cover. You need not be out of a creature’s line of sight to use this ability.

You become visible at the start of your next turn unless you have moved into a position that allows you to use the Hide action normally. You can use this feature a number of times equal to your Proficiency Bonus, regaining all expended uses when you finish a Long Rest.

Long Fade. If you take this trait twice, you have Advantage on your ability check when you take the Hide action from Fade Away, and you become visible at the end of your next turn instead of the start of your next turn.
