Choose either the second or the third option to learn Crucio. This will prompt options for you to learn it or to refuse. Speak with Sebastian, who eventually will offer to teach you Crucio or cast it on you. When you step through the third gate into another corridor, you’ll find the final note from Noctua near a locked door with the word ‘crucio’ written on the floor. If you do not put in the correct symbols by the time the snake makes a full rotation, be prepared for it to attack! As you explore the maze, be sure to keep an eye out for 3 more of Noctua’s notes. Find the symbols on each gate to help you solve it.

There are three gates with Slytherin lock puzzles. Speak to Ominis to unlock the door to the next room. To the right of the note is broken rubble – use Reparo to put it back together. You will not be able to go back once you pass through the door. One is part of a series of notes left behind by Noctua Gaunt. Once inside, you’ll approach two interactable items near a locked door. Light the three nearby braziers to open the door to Slytherin’s Scriptorium. You’ll need to convince a reluctant Ominis Gaunt to help. To unlock Crucio, start the quest called “In the Shadow of the Study.” When you meet Sebastian outside the Slytherin common room, he’ll tell you that only a Gaunt knows the location of the scriptorium’s entrance. For a complete walkthrough, see our In The Shadow Of The Study quest guide for more details.
