Succubus

Succubi are shapeshifting, female fiends who delight in the corruption of mortals through temptation. The male counterpart of a succubus is an incubus.

Appearance
Succubi are shapeshifters who can polymorph into Small or Medium humanoids. In their true form, succubi appear like beautiful women with a fiendish twist, almost tiefling-like, with clawed hands and leathery wings.

Abilities
The following is all drawn from the Monster Manual, but it is consistent with what a succubus is seen doing in and.

The method succubi typically use to corrupt mortal souls begins with approaching them in their sleep (passing through walls in ethereal form to get to the sleeping chambers) and filling their dreams with debauchery. The succubus proceeds to appearing in the flesh in the same form that she projected into the dreams, indulges the target's desires, and seduces the mortal into evil thoughts, words, and deeds of their own free will. This way, when the incubus/succubus kills the mortal, the target's soul descends to the Lower Planes. Therefore, although the succubus has a powerful magical charm, it only uses that as a last resort, typically to defend itself.


 * Resistances: Cold, fire, lightning, poison, and bludgeoning/piercing/slashing from nonmagical attacks
 * Etherealness: Switches between the Material Plane and the Ethereal Plane as an action.
 * Shapechanger: Magically polymorphs into a small or medium female humanoid, or back into her true form, keeping all equipment and statistics (except that without wings she cannot fly). Reverts to her true form upon dying.
 * Succubus - fl0wer-b0ys-art.jpgCharm: A humanoid the succubus can see within 30 feet must succeed on a Wisdom saving throw or be charmed for 1 day, during which the target follows the succubus's verbal or telepathic commands. The charmed creature can repeat the saving throw whenever it is harmed or given a suicidal command. If the succubus charms another creature, her charm on any other creature breaks. Once the creature makes a save or the effect ends, the creature is immune to that succubus's charm for 24 hours.
 * Telepathic Bond: A succubus can communicate at any distance and even between planes with any creature she has charmed.
 * Draining Kiss: Usually delivered as a coup de grâce, the succubus kisses a charmed or otherwise willing creature, which takes psychic damage and suffers an equivalent reduction in maximum hit points until the creature completes a long rest. If this reduces the creature's maximum hit points to zero, the creature dies.

A succubus can become an incubus, and vice versa, but they tend to prefer one form over the other.

Society
Succubi and incubi can have offspring with each other. Sometimes a succubus (or incubus) will procreate with a humanoid, and the result is a cambion.

Succubi (and incubi) sometimes operate in the same spaces as devils without being a part of that hierarchy. Likewise, they sometimes end up in the service of demons (see below, in History).

Campaign One: Vox Machina
When Vox Machina arrived in Emon for the first time, Syldor Vessar hired them to look for Sir Gregory Fince; when they investigated Fince's home, they found his tortured corpse in the basement, and they discovered and defeated a succubus and some demons.

Campaign Two: The Mighty Nein
In Chapter 13, the Mighty Nein investigated a demonic incursion in Asarius and interrupted a succubus and incubus attempting to corrupt a sleeping bugbear named Umadon. The party gave chase, following the fiends to an underground chamber where an Abyssal anchor had torn a rift through which demons could pass. The demons were attempting to build a stable portal from the Abyss beneath the city. The succubus used her charm to turn Caleb Widogast against the party, to terrible effect.

The background for the adventure Merry Spouses of Deastok in the Explorer's Guide to Wildemount notes that incubi and succubi have married into the powerful Truscan family of the Dwendalian Empire over the previous decade.
