Your Dexterity, Constitution, and Charisma scores increase by 1.

Concubi do not age in the same manner as many other beings. They feed on the libido of other beings by copulating with them to retain their beauty and youth. They can remain in this state so long as they feed regularly, mimicking immortality. If they do not feed, they begin to age, the process increasing the longer they go without feeding.

Unlike their fiendish counterparts, Concubi tend towards chaotic alignments due to their nature leaning heavily upon their own best interests. Rarely, if ever will you find an evil Concubi.

Concubi range from just under 6 feet to just over 7 feet tall. Your size is medium.

Base walking speed is 30 feet.

You have a flying speed of 30 feet. To use this speed you can’t be wearing heavy armor. Also you cannot end your turn in the air if you are wearing medium armor, you must land or otherwise keep yourself aloft or you will fall to the ground at the end of your turn. If you are wearing light armor or no armor you can stay in the air at the end of your turn.

Because you are a fiend, you have superior vision in dark and dim conditions. You can see in dim light within 120 feet of you as if it were bright light, and in darkness as if it were dim light. You can't discern color in darkness, only shades of gray.

Your creature type is considered to be both Fiend and Humanoid, and you are considered to have the Shapechanger tag. Additionally, you are vulnerable to radiant damage.

As an action, you can polymorph into any humanoid of your size that you have seen or back into your true form. However, your equipment does not change with you. You lose the fly speed trait if your current form does not have wings. If you die, you revert to your natural appearance. Your attributes are unaffected by this change. 

Concubi not only have a way with words, knowing just what to say, but their unnatural allure inspires people to confide in them and reveal their deepest desires. You have proficiency with the Persuasion and Insight skills.

Concubi possess unnaturally alluring eyes. All it takes is one glance and their eyes entrance anyone who returns their gaze. You can cast the charm person spell a number of times equal to your charisma modifier using this trait, using Charisma as your spellcasting ability. Casting in this manner does not require any material, somatic, or verbal components and does not consume a spell slot. You regain all expended uses of this trait when you finish a long rest.

The Concubi kisses a creature either willing and/or charmed by it. The target must make a Constitution saving throw against your Charisma Spell Save DC (8 + Charisma + Proficiency), taking 1d10 + Charisma Modifier psychic damage on a failed save, or half as much damage on a successful one. You regain hit points equal to half the damage dealt as you syphon energy from their body. The target's hit point maximum is reduced by an amount equal to the damage taken. This reduction lasts until the target finishes a long rest. After the target takes damage from this effect, it becomes immune to it for the next 24 hours.

You can speak, read, and write Common, Celestial, and Infernal.
