Feel free to use her to your dirty heart's desire, she is public propriety like all good propriety, the same applies to her dream world.
Appearence:
Leya is a beautiful succubus with pale skin, bright black lips and mesmerising red eyes, she has soft breasts, yet they vary in size, her waist is as(s) plump as(s) her big ass pun intended
Necessary Context for DM's:
Leya is a dream succubus and just like your waifu, she only exists in your dreams. Ok, jokes were made, but in essence Leya only can "engage" anyone inside their dreams, and leave the complicated magic bullcrap to me, but she only hitchhikes your head until you sleep, where she makes a dream world of your fetishes and probably also wears clothes that turn you on, or nothing at all.
Please roleplay acordingly, or don't, i can solve any cannon crisis you throw my way.
You could technically "pull her out" of the "dream world" with complex magic tho, but don't forget to make it clear wether she is fighting within her dream world or somewhere else, since it changes a lot the mechanical part.
The good part:
Passive: Wet dreams: Once every 3 turns when Leya makes an attack one memory of a certain move that our victim got hit by will be recalled inside our fortunate victim's head, causing him/her to suffer from said move. The balancing of this skill is up to the DM: Feel free to execute a finisher or a basic attack if you feel like it (The skill is rolled normaly, it can't critically succeed nor criticaly fail, has advantage if the PC is hypnotised and can trigger even if Leya fails her attack)
Passive scenario: Dream not the speedrunner
This is not a passive fof Leya, it is the natural state of the battlefield: Skills that require physical contact CAN still hit inside the dream, but even better: They do not require Physical contact anymore, as both battlers' minds are already close to each other due to 4th dimensional shenannigans.
Other changes:
Charmed does not increase damage anymore, instead it makes the Charmed one receptive in their mind, giving advantage on the next attack against he/she.
Hypnosis now gives Disandvantage for the Hypnotised's next attack
Raw disadvantage does not work here
People have advantage escaping "physical binds" and disadvantage escaping mental binds
Passives and actives that "put something" on another can be removed as a free action (Lipstick marks, bondage gear cuz that's a thing here, blindfolds, chains... well you get the point)
Mental black-out:
Leya kisses the PC leaving a sticky black mark on their projection(Kind of their dream avatar). Deals 4wp as damage and hypnotises.
Deepest fantasies:
Leya brings forth one of her target's deepest fantasies, learning one fetish of theirs and creating an ARTIFICIAL SCENE (More on that later). Always succeeds withing the dream world, yet deals no damage. Doesn't always succeed if this happens outside the dream world.
Smother your mind:
Leya uses a part of her body (Breasts, Thighs, Ass...) and wraps it around her enemy's head, smothering out their resistence. Inflits a bind that deals 3wp damage when hit and every subcequent turn, this bind is physical until you spend 2 turns bound by it (Fail/skip/stay stunned for 2 turns IN A ROW while bound), by this point her body is burned inside your head, where the bind will become mental and Leya will be able to use other skills while you are bound, that same bind can be executed mentally from now on, but she can still opt for the weaker physical counterpart if necessary. Important: The mental bind does allow other skill uses, and she will always use her ass unless she knows of a specific Fetish of the PC (She cannot use the mental bind with a body part that has not been used physically yet.)
Loving confort:
Leya sensually "walks"(as much walking as a dream can get) behind the PC, as she whispers sweet submission right into their ear and massages their back. Deals 4 wp and charms.
Artificial scene, might be redundant but i still feel like it should be here: An artificial scene is a projection of Leya and the target doing something lewd with each other (Use your creative genius), yet the target will feel as though that is actually happening to them as long as they are in the dream world, but on the real one it will feel like a simple porn movie. Every artificial scene has 0 hit points but has certain conditions to die: hitting an artificial scene with an "affection" move will backlash, while a more violent aproach will "dispel" it, ending its effect. The scene works by rolling a dice: It will inflict hypnosis(disadvantage) along with 2wp damage on the dream world, yet on the normal world it will only distract them by inflicting disadvantage.
There can be multiple scenes per person, yet there is no real reason to do so outside of the dream world.
The scenes work nearly like a summoned enemy, they need to be attacked to be dispeled, the attack CAN be interupted by physical means on the real world (Like an enemy stopping your attack, or some rought terrain..), but it will never miss withing the dream world (Cuz dream world has no physical barries)
The scene's rolls are done separetly from Leya's
The backlash from affection moves is: You are affected by your own move in the dreamworld, but on the lesser real world the scene will interact with you, sapping away 1 wp from your handsome ass.
Idk much about this one, i feel like i wrote a lot. Feel free to repourpose this character for some dungeon stuff, feel free to use it in a simple RP... as long as you can have fun i will be happy to be of help
