Using the Unforgivable Curses in Hogwarts Legacy

At some point in our lives, we wanted to break rules and be on the wrong side of the law. Well, you can do that in Hogwarts Legacy by using Unforgivable Curses. Judging from the name, Unforgivable Curses are like dark magic, immensely powerful and forbidden. 

Since they are considered Unforgivable, you might wonder if there are Consequences for Unforgivable Curses. Spoiler alert, there are no consequences for using them. Other characters might react shocked or in disbelief when they see you using it, but there are no real punishments. 

Now that you know it is safe, let us start knowing how to get them. You have the option to learn and use the three Unforgivable Curses, Crucio, Imperio, and Avada Kedavra. Crucio causes someone immense pain, Imperio controls them, and Avada Kedavra kills. They are awesome, right? 

Without further ado, let us start by guiding you on how to get and use the Unforgivable Curses in Hogwarts Legacy.

Crucio

These arts are learned as part of Sebastian Sallow’s questline, which begins in earnest once you travel to his family home and meet his sister as part of the main story. After this quest is completed, you must speak to Sebastian in the castle after he argues with his friend, Ominous. 

During this conversation, Sebastian will bring up Crucio and talk about attempting to find Slytherin’s Scriptorium. After speaking with him, he will send you an owl starting the side quest “In The Shadow Of The Study,” where you will learn the first Unforgivable Curse, Crucio. 

You, Ominous, and Sebastian all venture into Slytherin’s Scriptorium. After solving a few snake dial puzzles, where you need to match symbols on the gates with the symbols on the dial with a time limit, you will be trapped in a hallway where someone must cast the Crucio spell on someone else to proceed.

Ominous refuses to cast the spell again and warns that whoever does use it will be forever scarred, worse than the person on the receiving end. Sebastian says that he is pretty sure he knows how to cast it and asks you if you want to learn it and use it on him or have him attempt it on you. 

If you want to learn Crucio, you need to pick one of the two options where you learn the spell. Afterward, you will find a spellbook and this side quest will be complete.

Imperio

After completing the second trial and advancing to winter, Sebastian will ask you to come to speak with him in the Undercroft. He informs you that the spellbook you found contains information about an artifact that can reverse Dark Magic curses, which could save his sister. After some time passes, he will send you another message.

The next time you speak with Sebastian, it will be part of a main story quest called “In the Shadow of the Mine” where you must meet him at Overlook Mine. Around the same time you receive this quest, you will receive another message from Sebastian. 

In the message, he said he believes he has found the relic that could help Anne and has asked you to meet him at a catacomb near Feldcroft.

About halfway through the catacomb, Sebastian will suggest teaching you Imperio. If you want to learn Imperio, you need to choose the option where Sebastian teaches it to you.

Adava Kedavra

Sebastian will once again send you a message, asking you to meet him and Anne outside of Feldcroft. This starts the “In the Shadow of Hope” quest. Before you can continue you will need to have completed the main story quest “Lodgok’s Loyalty”. 

Ominous will message you, asking to meet you at the catacombs as Sebastian has become irrational and impatient. This starts the “In the Shadow of the Relic” quest, which is where you can learn Avada Kedavra.

Head back to the catacomb near Feldcroft, where you and Ominous need to head inside and find Sebastian. Head inside to find a ton of Inferni, which are supposedly being controlled by Sebastian. 

Ominous leaves to run interference with Headmaster Black and after finding Sebastian, his uncle arrives and a fight breaks out. After you defeat his Uncle Solomon, Sebastian casts Avada Kedavra on him. 

Anne burns all of the Inferni and the spellbook before leaving. Sebastian runs out of the catacomb, where you speak with him again. When you speak with Sebastian outside, side with him when given the chance. Eventually, he will ask if you want to learn Avada Kedavra and you should say you want to learn it. At this point, Sebastian will teach you the killing curse.
