Hogwarts Legacy takes you on a journey into the magical world of Harry Potter and Fantastic Beasts. Sebastian Sallow, a fellow student from House Slytherin, becomes your companion during the story's main and side quests. As Sebastian's quests near the conclusion, you are in a dilemma whether or not to report him.
Should I bring Sebastian back to Hogwarts Legacy?
In the Undercroft, you meet Sebastian and his friend Ominis Gaunt. You then have a conversation with Ominis to decide whether or not to bring Sebastian to Hogwarts for his crime. If you refuse to report Sebastian, you will be expelled from Hogwarts and will no longer be able to see him.
Sebastian's Unforgivable Curses: How to Learn
Crucio, Imperio, and Avada Kedavra are all curses that should be taken very seriously if you haven't yet acquired them. If you didn't receive them early enough, you may unlock them anytime later.
To acquire non-acquired curse spells, go to the Undercroft and ask Sebastian to teach them to you. The Undercroft entrance (first image) is located in the Astronomy Wing of Hogwarts Castle. Go down the stairs and you'll find the Undercroft door at the end of the corridor to your right.
