Hello everyone. Here is a guide on how to learn the Avada Kedavra curse. You can learn this spell during the quest called “In the Shadow of the Relic”, which is one of the final quests in Sebastian’s storyline.
This quest is quite late in the main story, so unfortunately, you won’t get to use Avada Kedavra as much as some other spells. Still, this doesn’t make it any less powerful. In fact, when talented, it is hands down the most powerful spell in the game.
Once you start the quest, Ominis will tell you to meet him and Anne at the Feldcroft Catacomb. When you get there, you’ll learn that Sebastian went into the catacomb and that the place is crawling with Inferi.
Shortly after entering the catacomb, you’ll be attacked by Inferi. Make sure to have Confringo or Incendio ready on your spell sets.
After defeating dozens of Inferi, Ominis will tell you the horrifying truth. Apparently, Sebastian somehow found a way to use the relic and control the Inferi.
Ominis will then decide to go back to Hogwarts and talk to Professor Black before he learns the story from someone else.
You’ll proceed deeper into the catacomb, battling any Inferi you encounter. Eventually, you will find Sebastian. He will say that he can use the relic to control the Dark Magic that cursed Anne.
Moments later, Solomon will arrive. He’ll quickly snatch the relic from Sebastian’s hands and destroy it.
All the nearby Inferi will turn hostile, so you’ll have to deal with them and defend yourself against Solomon. This will start Solomon Sallow boss fight. You can read the guide on how to defeat Solomon on Hard difficulty HERE.
Once you are done, Sebastian will use the Avada Kedavra curse on his uncle. Moments later, Anne will show up and burn all the remaining Inferi. Once she sees her Uncle’s lifeless body, she’ll use Bombarda to destroy the journal. She’ll be deeply disappointed in her brother, and shortly after, she’ll disapparate with Solomon’s body.
You’ll then need to follow Sebastian outside the catacomb. Once you are outside, initiate the conversation with him. He will tell you he had no other option but to use the Avada Kedavra curse.
There are two options for you to reply with. If you wish to learn this Unforgivable Curse, you should select the second option.
If you went with the second option, Sebastian will teach you how to cast Avada Kedavra.
Moments later, the quest will complete, and from now on, you’ll be able to use this Unforgivable Curse. Bear in mind that it has quite a long cooldown time, but with the talent that improves it and proper setup, it can instantly eliminate a whole group of enemies.
Hopefully, you found this guide helpful. Thank you for reading and see you soon with more guides for Hogwarts Legacy.
