As long as you're sure, pick “Yes please” to learn the curse. Keep in mind that there are no in-game consequences for using Avada Kedavra, or any of the other unforgivable curses, in Hogwarts Legacy. Other characters may comment on it, but it won't have any real impact.
Learning the Dark Arts through the Avada Kedavra Unforgivable Curse does not have any consequences in-game, other than NPCs reacting negatively to your use of it in public. Gameplay wise, it's even more beneficial to you, as it's another spell added to your loadout.
Does learning unforgivable curses matter in Hogwarts Legacy?
This is not the case, however, and the player's decision to use Unforgivable Curses has no effect on anything other than convenience in combat. Crucio inflicts damage-over-time, Imperio makes the targeted enemy attack other enemies, and Avada Kedavra is an insta-kill that shaves off a boss' incremental health bars.
What happens if you refuse to learn Avada Kedavra?
If you decide against learning Avada Kedavra from Sebastian, that's not the last chance you'll get to learn or use the spell. Once you return to the castle, you can visit Sebastian in the Undercroft in the Defence Against the Dark Arts tower, and ask to learn about it.
Can you turn Sebastian in and still learn Avada Kedavra?
As long as you haven't snitched on Sebastian, he will still be in his lair and willing to teach you Avada Kedavra. So when you're doing the quest, "In the Shadow of Fate," make sure to choose "We must not turn Sebastian in" when you're talking to Ominis Gaunt.
Can I get the good ending if I learn the unforgivable curses?
No, using Unforgivable Curses in the game will not result in a bad ending. The overall narrative remains unchanged, and there are no significant long-term consequences or repercussions for the player.
In the Bad Ending, your character again struggles to handle the Ancient Magic unleashed by Ranrok's defeat, but instead of getting help from Professor Fig, you absorb some of that magic into yourself. Gaining an extra burst of strength, your character is then able to seal away the remainder of the magic on their own.
Is there a downside to learning the unforgivable curses?
Learning and Using the Unforgivable Spells in Hogwarts Legacy Doesn't Have Many Consequences. Hogwarts Legacy does give players the opportunity to learn all three of the unforgivable curses, though the only time you can use these specific crime spells is off of the Hogwarts campus.
Visiting Azkaban in Hogwarts Legacy is only an option for players who chose a particular House at the start of the game, and it is only a very brief and linear visit, but it's still exciting to see and walk around such a storied locale, even briefly.
Should you turn Sebastian in or not Hogwarts Legacy?
Should You Turn Sebastian In Or Not? Players who chose not to learn the three Unforgivable Curses when they had the chance earlier but want to learn them now should choose not to turn Sebastian in; once he is gone, the only way to acquire these spells is for players to begin a new game and start over.
Do you get a second chance to learn Avada Kedavra in Hogwarts Legacy?
If you're having second thoughts on whether or not to learn Avada Kedavra, you can learn it from Sebastian later on if you make the certain story choices.
Do you have to agree with Sebastian to learn Avada Kedavra?
Now, Sebastian Sallow will offer the hero to proceed to learn the spell. If players wish to learn Avada Kedavra immediately, they should select "Yes, please". Now, players will immediately learn Avada Kedavra. Incorrect answers will result in Avada Kedavra being unavailable at this stage.
Morality explained. While you can make certain choices and use spells that may be considered morally questionable, you cannot canonically be evil in Hogwarts Legacy. Essentially, there's no version of the story where you'll be recognised as inherently evil and rise up as a proto-Voldemort.
You can also learn it in the next Sallow relationship quest where you should tell Ominis Gaunt "We must not turn Sebastian in." Speak to Sebastian in the Undercroft after this and he'll teach you any Unforgivable Curses you have missed up to that point, including Avada Kedavra.
You can chose to contain or control the reserves of dark magic the Keepers are sworn to protect. Any option you chose results in the same boss fight against Ranrok, and Professor Fig dying. There's no way to save him even if you made the “good” decisions.
Does learning curses make you evil Hogwarts Legacy?
No, there is no morality and the only people who care are the ones you use them on, use Imperio on any human or goblin and they complain about it once the effects run off.
What happens if you learn dark arts in Hogwarts Legacy?
There are no consequences to using any dark arts in this game nor their associated talents. In fact, using all 3 unforgivable curses and the entire dark arts talents tree makes you OP. That's the only real consequence.
If you turn it down, you can learn it later. Crucio deals high damage and “curses” the victim, making them more susceptible to other forms of damage in combat.
Teach me the Cruciatus Curse and I'll cast it on you. The major choice here is whether the player will learn Crucio or not at this point in the game (it can still be learned later on). The choice of whether you or Sebastian casts it has no effect on the main story.
This will be easiest to do if you are sorted into Slytherin but is possible for players from any House. When playing through 'In the Shadow of the Relic', you will need to battle a cave full of Inferi and then a final boss.
