Fiendish Charm

One of your ancestors was a succubus, incubus, nymph or other charismatic Fiend or Fey, or you’ve been blessed or possessed by one. You gain the following benefits.

Ability Score Increase. Increase your Charisma score by 1, to a maximum of 20.
Irresistible Allure. You have Advantage on Charisma (Persuasion) checks made to interact with a creature that is normally attracted to your species and gender. 
Fiendish Enticement. If you interact with a Humanoid for at least 1 minute, you can attempt to entice it. The target must succeed on a Wisdom saving throw or be Charmed by you for 1 hour or until you or your companions do anything harmful to it (DC 8 + your proficiency bonus + your Charisma modifier). If a target succeeds on its saving throw, the target knows it was Charmed by you if the actions you convinced it to take clashed with its values. Once you use this feature, you must finish a Long rest before you can use it again.
Infernal Touch. You can touch a creature to assail it with a fiendish, rapturous chill. As an action, make a melee spell attack. Charisma is your spellcasting ability for this feature. On a hit, the target takes 1d6 Psychic or Necrotic damage (your choice), and it can’t take a Reaction until the start of its next turn. You regain Hit Points by an amount equal to the damage inflicted. This damage increases when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6). You can use this feature a number of times equal to your Proficiency Bonus and you regain all expended uses when you finish a Long Rest.
