Way of the Kitsune

Monks of the Way of the Kitsune channel the ancient, trickster magic of the spirit foxes. Through rigorous spiritual training, these monks bridge the gap between the material realm and the fey-like magic of the world. They excel at manipulating spiritual energy, commanding body and soul alike.

Level 3: Kitsunebi

As a Bonus Action, you can expend 2 Focus Points to conjure tiny, floating flames in a 10-foot radius centered on your space. Any hostile creature in the area when it appears must make a Wisdom saving throw. 

On a failure; the creature sheds dim light in a 5-foot radius, cannot benefit from being invisible, and the next attack roll made against them has Advantage. This effect lasts until the end of your next turn, or until you use a Free Action to end it.

On a success; no effect happens.

Level 6: Henge

You can use an Action to expend 1 Focus Point to change your appearance and your voice. You determine the specifics of the changes, including your coloration, hair length, and sex. You can also adjust your height and weight, and can change your size between Medium and Small.

You can make yourself appear as a member of another playable species, though none of your game statistics change. You cannot duplicate the appearance of an individual you have never seen, and you must adopt a form that has the same basic arrangement of limbs that you have. This trait does not change your clothing and equipment.

While shape-shifted with this trait, when you make a Charisma check, you can expend 1 Focus Point to roll a d4 and add the number rolled to the check. You can choose to use this feature after you make the ability check, but before the GM determines the outcome.

You stay in this new form until you become incapacitated or you take a Free Action to willingly revert to your true form. 

This transformation is a mystical glamour that alters your corporeal form, but not your true nature or spiritual presence. A creature can discern the disguise with magic that reveals illusions or true forms, at the GM’s discretion. 

Kitsune no Sugata

As a bonus action, you can expend 3 focus points to transform into a magical fox. Your size changes from Medium to Small. This form lasts until you use a free action to end it, you use your Henge feature, you are incapacitated, or the temporary hit points granted by this feature are reduced to 0.

While in this form, you gain the following benefits:

• Spirit Sight: You gain darkvision out to a range of 60 feet.
• Fox Agility: You ignore nonmagical difficult terrain.
• Keen Senses: You have advantage on Wisdom (Perception) checks that rely on hearing.
• Spirit Resilience: You gain temporary hit points equal to one roll of your Martial Arts die + your Monk level.
• Fanged Strikes: Your unarmed strikes deal an extra 1d4 magical piercing damage. Increases to 2d4 at level 17.
• Quadruped: You have disadvantage on all skill checks requiring the use of hands.
• Wise: Despite your altered form, you can still speak, use your Flurry of Blows, Step of the Wind, and other Focus Point-based monk features while in this form.

Level 17: Kitsunetsuki

As an Action, you can expend 4 Focus Points to attempt to possess one humanoid you can see within 5 feet of you. The target must make a Wisdom saving throw (a creature can choose to willingly fail this save).

You must concentrate on this effect as if concentrating on a spell.

On a Failure: Your physical body falls unconscious, and your spirit enters the target's body. The target is Incapacitated and cannot control its body, though it retains full visual and auditory awareness. 

While possessing the target, the following rules apply:

• Borrowed Form: You perceive through the target’s senses and control its body. You use the target’s Hit Points, Senses, Strength, Dexterity, Constitution, Armor Class, and Speed.
• Dominating Will: You retain your own Languages, Intelligence, Wisdom, Charisma, and proficiencies. You cannot use your own class features or spellcasting, nor can you use the target's class features, spellcasting, legendary traits, or special actions, except for the Kitsunetsuki feature.
• Separation: The true body and possessed body are separate creatures for all purposes, including targeting, areas of effect, damage, and conditions.
• Defiant Host: At the end of each of the possessed creature’s turns, it can repeat the Wisdom saving throw, ending the effect on a success.
• Tenuous Bond: Whenever either your true body or the possessed body takes damage, you must make a Concentration Check.
• Mortal Coil: The possession ends early if either your true body or the possessed body drops to 0 Hit Points.
• Violent Severance: If possession ends either due to Defiant Host or Tenuous Bond, both your true body and the possessed body take 2d10 psychic damage.

When the possession ends, your spirit instantly returns to your true body. If your true body has at least 1 Hit Point, it immediately regains consciousness. Whether the target succeeds or fails its saving throw against this feature, it becomes immune to your Kitsunetsuki for the next 24 hours.
