Your Charisma score increases by 2, and your Dexterity score increases by 1.

Succubi and Incubi mature at the same rate as humans, though tend to live as long as they continue to feast on souls periodically.

Imbued with their innate entrancing ability, most succubi and incubi are evil. Outcasts of their society however, in rare situations may escape to the Material Plane and lean toward neutrality.

Succubi and Incubi have about the same size and build as humans. Your size is medium.

Your base walking speed is 30 feet.

Thanks to your fiendish heritage, 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. Thanks to your heritage, your darkvision is unusual: everything you see in darkness is a shade of deep red.

Some fiends enjoy manipulating their prey, while others prefer to seduce them into an early grave. You have proficiency in either the Persuasion or the deception skill.

 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.

You walk amongst everyday folk like you are one of them. You can cast a fiendishly altered version of disguise self without expending a spell slot. Instead of its normal duration, it lasts until you are able to concentrate on it as if it was a spell or until you dismiss the illusion.

A creature can recognize your disguise by making a successful Wisdom (Insight) check against your Fiend Save DC.

You have a small set of wings on your back. However, these wings are not strong enough to hold your weight for an extended period of time. You can use your wings to suddenly thrust yourself forward 10 feet on the battlefield as a bonus action. This movement doesn't provoke opportunity attacks. You regain the ability to use this feature after taking a short or long rest.

 Once you reach 5th level, you gain the ability to drain the life of a foe with your deadly kiss. As an action, you may kiss a target within 5 feet of you. The target must succeed on a Constitution saving throw or take necrotic damage equal to your character level + your Charisma modifier. The DC equals your Fiend Save DC. Additionally, you gain hit points equal to the damage dealt. After you use your draining kiss, you can't use it again until you finish a long rest.

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