The Dark Mistress

You have made a deal with a mysterious fiendish entity of great power and allure: a Dark Mistress. A Dark Mistress is generous with her gifts but requires absolute loyalty from her servants. Strangely, a Dark Mistress does not often seem to have any care for her pactmaker's own alignment. She tends to remain neutral in the affairs of demons and devils, sending out her pactmakers to accomplish goals for her own personal gain. Such missions normally involve varying tasks such as the recovery or theft of a magic artifact, rooting out the deepest secrets of important figures, or something as petty as gathering a collection of rare jewelry she particularly likes.

The true location of a Dark Mistress' otherplanar residence is a closely guarded secret and only her chosen favorites know of it. When she wants to speak to her servants personally, she often teleports them directly to herself in her lair to give orders before tossing them right back out from whence they came.

Gift of Endurance

Distracting Allure

At 1st level, a distracting allure surrounds your appearance, affecting the minds of your enemies in combat. When you aren't wearing armor, you may add your Charisma modifier to your AC.

Dark Charmer

At 6th level, you are given some of the Dark Mistress' power to better charm humanoids. You learn the charm person spell if you do not know it already. It does not count against the number of spells you know. When you cast charm person against a humanoid you or your companions are fighting, it does not have advantage on its Wisdom saving throw. In addition, your dark power makes you immune to being charmed yourself.

Fiendish Arbiter

At 10th level, you have been granted supernatural resistance to all forms of heat. You gain resistance to fire damage. You also now carry an unseen warding mark of the Dark Mistress within you. Demons and Devils within 30 ft. of you will naturally sense this mark and become passive towards you, unless you are acting in an obvious manner against their interests. If they do become hostile, they have disadvantage on attack rolls against you.

Summon Servants

At 14th level, you gain the full trust of your Dark Mistress and may use an action to summon some of her lesser servants. When you summon these servants, a number of succubi or incubi equal to half your Charisma Modifier (rounded down) appear in unoccupied spaces of your choice within 60 ft. of you. The fiends remain for a number of hours equal to your Charisma modifier and will follow your orders. They will remain until you dismiss them as a bonus action or until you die. Should you fall unconscious in combat, they will attempt to stabilize you, carry you away, and flee any battle to bring you to safety. You may use this feature once per long rest.
