Speak with Ominis
To gain access to the Scriptorium, players must first persuade Ominis to reveal the location of the door. Players will be tasked with opening the Slytherin’s door.
Open Slytherin’s door
To open the Slytherin’s door do following : First locate the three Braziers using Revelio. From where Ominis is positioned, there are three braziers (snake-based torches) visible. Two Braziers are on the left and one on the right side.
You need to cast Confringo/Incendio on three pillars ( braziers ). All three Pillars must be on fire, thus you must move very quickly to open a a hidden path. The quickest way is to shoot Confringo while standing in a corner. If you are not quick enough, they will all burn out.
Explore beyond the doorway
After you open the first door, you will be able to enter the dungeon. Go down the stairs that will lead you to the secret passage. And then you’ll see some broken pieces on the floor and another door in front of you.
Figure out how to progress
Cast Reparo spell on the damaged stone to repair the structure.
Speak with Ominis about the hissing
Now, Omnis will explain that he can hear a voice, and he can use this to open the door. The player needs to speak with Omnis and choose the option to encourage him to trust his instincts. After that, Omnis will open the door, and the player can proceed with the quest. Wait for Ominis to open the door.

Talk to Sebastian
Sebastian describes what needs to be done and requests that you consult with Ominis about it.You can agree, or you can decline and urge Sebastian to talk to his friend.
Talk to Ominis about Crucio
He claims that in order to cast the magic, one must truly believe in it, which he has never done. It will have to be done by one of you.
Talk to Sebastian
He’ll inform you that either he or you can cast it. After that , In the dialogue, you will have three options
- Very well, I don’t want to learn the Cruciatus Curse.
- I want to learn Cruciatus Curse. But you must cast it on me.
- Teach me the Cruciatus Curse, and I’ll cast it on you.
Upon selecting the second option, Sebastian will proceed to cast the curse on you after you have learned it, resulting in the opening of the door, as depicted in the images below.
