Concubus

Concubus Features

Source: Monster Manual
Concubi, or succubi and incubi, are the iconic depiction of lust. Feared for their typically evil nature and ability to steal one's soul, concubi are fiends who wield subtle illusions and enchantments to tempt their victims into forfeiting their eternal souls.
Ability Score Increase Your Dexterity score increases by 1, and your Charisma score increases by 2.
Alignment Even with their fiendish natures, concubi often tend to be rather neutral when it comes to alignment. They first of all serve themselves, and live to spread their lust. They care little for mortal life, and serve when they see it in their interest to serve. Due to this they are often chaotic in nature.
Size Succubi are shapeshifters; however, in general, they are similar in size to most other humanoid races. Your size is Medium.
Speed Your base walking speed is 30 feet.
Darkvision Because you are a fiend, you have superior vision in dark and dim conditions. You can see in dim light within 60 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.
Fiendish Nature 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.
Shapechanger As an action, you can transform your appearance or revert to your natural form. You can't duplicate the appearance of a creature you've never seen, and you revert to your natural form if you die.
You decide what you look like, including your height, weight, facial features, the sound of your voice, coloration, hair length, sex, and any other distinguishing characteristics. You can make yourself appear as a member of another race; you lose the flying speed granted by your wings trait if your current form does not have wings; otherwise, none of your game statistics change. You also can't appear as a creature of a different size than you, and your basic shape stays the same; if you're bipedal, you can't use this trait to become quadrupedal, for instance. Your clothing and other equipment don't change in appearance, size, or shape to match your new form, requiring you to keep a few extra outfits on hand to make the most compelling disguise possible.
Even to the most astute observers, your ruse is usually indiscernible. If you rouse suspicion, or if a wary creature suspects something is amiss, you have advantage on any Charisma (Deception) check you make to avoid detection of your true nature.
Unnatural Beauty You gain expertise with the Persuasion skill. You have advantage on Charisma checks concerning seducing and enticing someone. Additionally, If you spend 1 minute talking to someone who can understand what you say, you can make a Charisma (Persuasion) check contested by the creature's Wisdom (Insight) check. If you or your companions are fighting the creature, your check automatically fails. If your check succeeds, the target is magically charmed by you as long as it remains within 60 feet of you and for 1 minute thereafter. When the charm wears off, the target will not realize that they were charmed by you. If the target's check succeeds they realize there is something off about your unnatural beauty and charisma. They will not trust you, and you have disadvantage on Charisma checks with them as your target. A person succeeding on a general insight check with you as their target, against a DC of your persuasion bonus + your deception bonus will realize that there is something off about your unnatural beauty and charisma. They will not trust you, and you have disadvantage on Charisma checks with them as your target.
Wings You have a pair of wings that give you a flying speed of 30 feet. You cannot use this fly speed if you are wearing medium or heavy armor or if your current form granted by your shapechanger trait does not have wings.
Language You can speak, read, and write Common, Abyssal, and Infernal.
Telepathy You can speak telepathically to any creature you can see within 30 feet of you. The contacted creature doesn't need to share a language with the monster to communicate in this way with it, but it must be able to understand at least one language.
Radiant Vulnerability All radiant damage does double damage on you.

Common Etiquette Rules

Concubi often live up to their reputation, acting as seductive females or males to lure males and/or females into relinquishing some of their life-force. Particularly adept at controlling others in the peak of their strength, they're often employed - albeit reluctantly - by others to act as crowd control, or to tame certain creatures. Most of them share the nature of their reputation; flirtatious. They avoid fighting where possible, instead choosing seduction or fleeing.

History

Concubi inhabit all of the Lower Planes, and the lascivious dark-winged fiends can be found in service to devils, demons, night hags, rakshasas, and yugoloths. Asmodeus, ruler of the Nine Hells, uses these fiends to tempt mortals to perform evil acts. The demon lord Graz'zt keeps succubi and incubi as advisers and consorts.
