Hogwarts Legacy – All Three Unforgivable Curses (How to Get)

If you do not want to read spoilers, but enjoy the plot, but do not know where to find spells, I’ll just tell you in one sentence. Complete all tasks from Sebastian Sallow. After completing all his missions you will get all three Curses.

Avada Kedavra

I think most of the players just wanna kill someone and for that they need exactly this spell. However, if you want to unlock this you will need 28 level, so you will be able to do it only at the end or after the main story. You can unlock and get the Avada Kedavra by progressing through Sebastian’s Relationship questline, where you have to complete the “In the Shadow of the Relic” quest to get “Avada Kedavra”.

  • You have to progress the quest and chase down Sebastian into the Feldcroft region.
  • Over there, interact and talk to Sebastian Sallow.
  • While having the conversation, select the “Everyone should know the curse” option.
  • Then, select the “Yes, please” dialogue option to learn the killing curse.

This would conclude In the shadow of the Relic quest and reward you with the Avada Kedavra spell.


The first of the three Unforgivable Curses and that gives the spell-caster total control over their subject. If you think that you can only “ask” enemy to walk as you want, you wrong. This is to useful curse in the battles, that i extremely advice to use. Enemies under this spell will have glowing white eyes and a green X-mark when targeted.. And as said Alastor Moody “You can ask him to drown if you want to”.

This spell is in the quest “In The Shadows Of Time”. You can get this quest by checking the Owl Post in your menu for a letter from Sebastian around Level 17.

  • You have to progress the quest where you will come to Sebastian’s childhood house.
  • When you come there, enter the cave.
  • Uncover the ancient relic.
  • At the end of the mission Sebastian can teach you the curse.


Another Unforgivable Curse that is not allowed to use, but of course as you are a player you can do it without any restrictions. You have first to complete a series of quests in Sebastian’s quest line. This spell will damage the enemy during the whole battle. Also it is the first Unforgivable Curse that was used by Harry Potter in 5th book.

So to unlock it, you’ll be offered the quest “In The Shadows Of the Study”.

  • You have to progress the quest where you will enter the Slytherin’s Scriptorium where you’ll find a door that requires the unforgivable spell to be used.
  • Over there, interact and talk to Sebastian Sallow.
  • While having the conversation, select to perform the curse by yourself option.
  • After that you’ll be able to use the spell.

  3. I covered my mouth in shock after the cutscene before learning avada kedavra. Wanted to tell him no one should know this spell afterwards but since there were only two options, it was clear I need to tell him everyone should know it in order to be able to learn it myself. Sucks I had to go against what I would have chosen and agree with him but I think it’s worth it, if you enjoy playing with these super powerful spells.

  4. Thanks, you helped me get to the part where Fig dies, Rookwood curses Anne and blames the goblins, and Niamh and Isidora die
