whore queen patron

Warlock Patron: The Whore Queen
Your patron is a powerful incubus, succubus, or other corrupter of mortals - though occasionally powerful evil-aligned nymphs will grant similar abilities.  Notable individuals include Malicanthet (the queen of Succubi), Fierna (the daughter-consort of Belial), or Belial himself.

1. Alluring Gaze: As an action, you can enthrall a nearby creature with your gaze.  Choose a creature within 30'; they must make a Wisdom saving throw against your spell save DC.  If they fail, they are charmed by you for up to a minute.  If at any point line of sight is broken between you and the charmed creature, or you are more than 60' away from each other,  the effect ends instantly.  You can use this ability twice, and regain all expended uses when you complete a short or long rest.

6. Stay the Hand: When a creature within 30' targets you with an attack, you can use your reaction to attempt to charm that creature.  They must make a Wisdom save against your spell save DC; if they fail, they are charmed by you until the end of your next turn.  They must choose a different target with their attack, or lose their action.  (A charmed creature is not compelled to harm themself or an ally, but they will not harm you.)  Once you use this ability, you cannot use it again until you complete a short or long rest.

10. Know Desire: You may use your action to learn the surface thoughts of a creature you have charmed, as the spell Detect Thoughts.  You cannot use subsequent actions to probe deeper using this ability.

14. Kiss of Death: You may use your action to kiss a creature that is currently charmed by you and attempt to drain their vitality.  A creature kissed by you must make a constitution save against your spell save DC; if they fail, they immediately fall to 0 HP.  If they succeed, they instead take 10d10 psychic damage, which may kill them anyway.  Once you use this ability, you cannot use it again until you complete a short or long rest.

New Invocation: Love's Betrayal
Prerequisite: archfey patron or whore queen patron
When you end a charm effect on a creature by dealing damage to that creature, you deal additional psychic damage equal to your Warlock level plus your Charisma modifier.

New Invocation: Savored Sting
Prerequisites: whore queen patron, pact of the blade
You can create an ornate whip of black leather, studded with tiny red barbs, using your Pact of the Blade feature.  When you hit a creature with this weapon, you can expend a spell slot to deal an additional 2d8 psychic damage to the target per spell level.  Dealing damage to a creature with this weapon does not end any charm effect on that creature unless you choose to end it.
