Try to seduce the noble lord

You cast a spell called "enhance ability" to become more charismatic and persuade the guards and servants to make an exception and let you exchange a word with the noble lord.

You have only a few seconds to talk with him when he's arriving at home on his carriage, your words are sweet, and he smiles at you, he orders the guards to go away
The noble lord is a big man; he's tall, muscled, and has a big belly. The man is wearing silk clothes, and his fingers are full of rings and he has a collar with a big golden key with the word "D6". The stone!! This key will lead you to the stone!
"Oh, I never noticed you in town, you must be new on these lands, I never miss a beautiful girl like you" he smiles.

But before you can answer, another person descends from the carriage is the High Priestess, dressed in noble clothes, without wearing her habit, but you recognize the ring with the symbol of the church, the magical **** of the item is overwhelming.

"This one stinks of desperation," she says

The Noble Lord ignores the priestess and says. "Stay as my honored guest, dine with me tonight, and we shall discuss mutual benefits."
After that, he walks into the palace. But he turns to look at you one more time and winks at you.

A servant guides you to your room and gives you all the necessary instructions about the palace.
When he leaves the room, the high priestess enters and says.
"You can't fool me, you are using your magic to enhance your beauty and charisma, speak now!"

You have to decide what to do...
You can get rid of her using your magic and convince the noble lord to let you access the stone, or you can speak with her and try to avoid the conflict.
