Temptress

You do not hide in the shadows. You become the light that every eye is drawn to, the warmth that makes people forget the door, the quiet moan on the air that pulls attention like a hooked finger.

A Temptress walks into a room and the world rearranges itself around their body. A soft glow clinging to bare skin, a lingering scent of musk and perfume, the deliberate sway of hips, the way candlelight kisses the hollow of a throat; these are their tools. They make Performance into a living, breathing alternative to Stealth: not vanishing, but redirecting. Guards forget the corridor. Nobles forget their suspicions. Monsters forget everything except the curve of their silhouette and the promise in their voice.

While every gaze is locked on them, they can gift the Invisible condition, the benefits of being Hidden, or any stealth-enhancing effect they carry to a willing ally, letting that ally slip past or strike while the Temptress holds the room’s attention. The same distraction lets them (or an ally) trigger Sneak Attack as if an ally were already in position. At higher levels their presence cuts deeper still, adding raw damage to every precise strike, and, when they choose, turning overwhelming pleasure itself into a weapon that can make a creature concede, collapse, or faint from pure sensation.

They are both the decoy and the blade, the distraction and the payoff, equally at home slipping a party through a guarded hall or reducing a target to trembling, pliant helplessness between silk sheets. Every tool they possess can serve the mission… or far more personal hungers and greed. The choice is always theirs after all.

Level 3: Alluring Distraction

You develop a special application of the Performance skill that functions as a Charisma-based alternative to Stealth for the purpose of creating distractions and remaining unnoticed through pure presence. When you would make a Dexterity (Stealth) check to hide, move quietly, or avoid detection, you may instead make a Charisma (Performance) check.

Which is then reworked to be called 'Alluring Distraction'.

You gain proficiency in Performance if you don’t already have it. If you already have it, you gain Expertise in Performance instead.

On a success, you gain the benefits of being hidden from creatures who failed to notice you, but the method is different: instead of vanishing, you have redirected their attention. Creatures who fail the opposing Wisdom (Perception) or Intelligence (Investigation) check are distracted by you (or by the display you create). They have disadvantage on Wisdom (Perception) checks to notice anyone other than you until the start of your next turn or until you attack, cast a spell, or otherwise break the performance. Which you can keep it active by continuously rolling performance; except as an action or bonus action instead; but it is considered to be using concentration instead, failing breaks and resets it.

You can use Alluring Distraction even while in plain sight, provided there is at least one creature present who can see or hear you.

When you successfully use Alluring Distraction, you can choose to transfer certain beneficial conditions; or those that affect you currently, to a willing creature within 30 feet that you can see. The transferred effect ends on you and begins on the chosen creature. Eligible effects include the Invisible condition, the benefits of being Hidden, or any magical or class feature that grants advantage on Stealth checks or allows you to hide as a bonus action. The transferred effect lasts for its normal duration or until the recipient breaks it (whichever comes first). You can do this a number of times equal to your Charisma modifier (minimum once), and you regain all expended uses when you finish a long rest.

Additionally, when a creature is distracted by your Alluring Distraction (or is Charmed by you), you can trigger your sneak-attack for yourself; or give it to any ally instead if they strike it instead; only applies once per ally though and it can only be applied once per target.

No Proficiency = Proficiency

You gain Proficiency in performance

Proficiency = Expertise

You gain Expertise in performance due to you already having Proficiency in it

Level 3: Velvet Knowledge

You learn the thaumaturgy and prestidigitation cantrips. Charisma is your spellcasting ability for both. When you cast either, you can choose to make the effect distinctly sensual or intimate if you want (like a soft glow that clings to bare skin like a lover’s breath, a faint scent of warm perfume or musk that lingers in the air, a low, lustful moant that gathers everyone's attention, or a subtle shimmer that draws the eye along the curve of your body, a fleeting flush of heat across someone’s skin, etc).

In addition, whenever you make a Charisma (Persuasion), Charisma (Deception), or Charisma (Performance) check, you can add a 1d4 to the roll.

Additionally at level 9 (manually apply btw) you add half your proficiency bonus to the d4, increasing it equal to the amount of d4's you have to it (applies to guidance and any race that adds a d4 to it like vedalken towards performance).

Level 9: Honeyed Blade

Your distractions now cut deeper in a multitude of ways.
When you deal Sneak Attack damage, add a bonus to the total equal to half your proficiency bonus (rounded up) for each Sneak Attack die you roll. (Example: at 5d6 with proficiency +4, half rounded up is +2; which you add +2 damage per die, for a total of +10 extra damage.)

In addition, when a creature is currently distracted by your Alluring Distraction, when an ally use you sneak attack on them the damage bonus applies still; but ontop of that; you can now apply the sneak attack bonus to any form of... sensual attack; or rework it for when you use it to a new form of hp letting them concede or faint from it if it's required; with the DM choosing to use the base hp or half the hp for what form it uses.

(Virgins should get either half the HP or a quarter)

Level 13: Irresistible Urge

When a single creature or more is distracted by your Alluring Distraction, you can choose one of the following additional effects (no action required) wth only a max of being expended until it is broken/reseted and used again (concentration breaking breaks/resets it):

The creature has disadvantage on their first attack roll before the end of its next turn (for 1 round or more, and the first attack for each turn).
The creature’s speed is reduced by 10 feet until the end of its next turn as it lingers, distracted by your presence (for 1 round or more).
The creature drops concentration automatically.
The creature begins focusing you specifically for their own personal-gain (for 1 round or more). 

You can use this feature a number of times equal to your Charisma modifier (minimum once), regaining all uses on a long rest.

Level 17: Apex Temptress

Your presence becomes almost overwhelming. You gain the following benefits:

Alluring Distraction (Performance) checks are made with advantage.

The bonus from Honeyed Blade: You now add your full proficiency bonus (instead of half, rounded up) to each Sneak Attack die.

When you successfully force a creature to concede, collapse, or faint with a sensual application of Honeyed Blade, you can choose to make the effect last for 10 minutes (or more if combat ended). The creature remains pliant, deeply preoccupied with you, and will not willingly act against you or your allies during this time unless forced.

Once per long rest, when you use Velvet Knowledge 1d4 (or guidance, or whatever) on a Charisma (Persuasion), Charisma (Deception), or Charisma (Performance) check, you can treat all d4s as having rolled their maximum value (4) before adding the proficiency-based bonus.
