The Slytherin student companion Sebastian Sallow in Hogwarts Legacy practices dark magic, and the game allows you to either turn him in for his taboo knowledge or not give any report against him. A reasonable question of your morals, the question becomes more complicated as Sebastian remains the only character that teaches the Unforgivable Curses. If you want to learn Imperio, Crucio, or the instant death spell Avada Kedavra, you can only do so by choosing the proper dialogue with Sebastian and increasing your relationship level with him.

The opportunity to turn Sebastian in comes from the main story quest, "In the Shadow of Fate," after you have completed the first Beasts class. The other missions, "The Helm of Urtkot" and "The Caretaker's Lunar Lament," must also be finished to interact with Sebastian. If you're horrified by Sebanstian's blatant use of outlawed magic, you can turn him in soon after the quest to see him expelled from Hogwarts and thrown into Azkaban for the remainder of the story.

Is It Worth Turning In Sebastian In Hogwarts Legacy

Sebastian Sallow will give you the only way to embrace the path of a dark wizard, eventually allowing you to unlock each of the Unforgivable Curses. These spells are by far the most powerful spells to use during combat, with Hogwarts Legacy's Avada Kedavra simply eliminating any enemy in a single hit.

Beyond some disapproving dialogue from other characters, there are no downsides to learning Avada Kedavra or other Unforgivable Curses from Sebastian, making it preferable to not turn him in.

Although you still need to choose the best conversation choices when interacting with Sebastian, simply having him still around creates these chances in the first place. The character has an interesting story path in Hogwarts Legacy revolving around his family and past, so you would be missing out on a compelling narrative if you turn him in. If you do turn Sebastian in, it will lock out additional content that could extend your time in the Wizarding World's darker side. If players are interested in seeing both outcomes or want to know if they turned in Sebastian, they can have a look at Northalix's video on Youtube for more context:

To speak strictly on benefits to combat, every Unforgivable Curse meshes well with other destructive magic to give you powerful spell combos. Taught periodically in quests with Sebastian, each of the three spells have long cooldowns due to their compelling results in battle. Whether you choose to turn in Sebastian Sallow or not, you should consider the amount of fun you might miss by losing access to Hogwarts Legacy's Unforgivable Curses and the experimentation that comes from having new magic.
