Explore the nun's quarters

You step into a long corridor, with black water on the floor and a big wooden door at your right.
You avoid the water and quietly open the door.

You notice a huge ornated wardrobe with the nun's clothes, an altar with holy items, and at the end of the room in front of a candle, a nun is reading a book and praying (but she didn't notice you).

You have a few options here:

• Disguise as a nun, being unnoticed inside the church can be an advantage.
• Steal the holy items, these items can give you some advantages.
• Knock out the nun and using her as a hostage can be helpful.
