The lady of pain could be any kind of being who deals in pain, assassination, death. Your patron may expect you to commit acts of violence, torture, or assassination. They may require ritualistic branding of the self, flaying one's own skin, or otherwise bizarre acts of patronage.

Taste the Pain

Starting at 1st level, your exposure to pain gives you the ability to share that pain with others. As a bonus action, choose one creature you can see within 30 feet of you. The target is cursed for 1 minute. The curse ends early if the target dies, you die, or you are incapacitated. Until the curse ends, you gain the following benefits:

• You gain a bonus to damage rolls against the cursed target. The bonus equals your proficiency bonus.
• Any attack roll you make against the cursed target is a critical hit on a roll of 19 or 20 on the d20.
• If the target is surprised when you hit them with an attack, the attack is an automatic critical hit.

You can’t use this feature again until you finish a short or long rest.

 

The Lady's Consort

At 1st level, you acquire the training necessary to effectively spread the pain. You gain proficiency with stealth, disguise kits, and one martial weapon of your choice. 

Retreat into night

Starting at 6th level, you can vanish in a puff of darkness in response to harm. When you take damage, you can use your reaction to turn invisible and teleport up to 60 feet to an unoccupied space you can see. You remain invisible until the start of your next turn or until you attack or cast a spell.

Once you use this feature, you can’t use it again until you finish a short or long rest.

Uncanny Dodge

Starting at 10th level, when an attacker that you can see hits you with an attack, you can use your reaction to halve the attack’s damage against you.

The Lady in Waiting

Starting at 14th level, when you hit a creature with an attack, you can use this feature to instantly transport the target through the lady's maze.

At the end of your next turn, the target returns to the space it previously occupied, or the nearest unoccupied space. If the target is not a fiend, it takes 10d10 psychic damage as it reels from its horrific experience.

Once you use this feature, you can’t use it again until you finish a long rest.
