To unlock Avada Kedavra in Hogwarts Legacy, you must complete the side quest In the Shadow of the Relic.

This is one of the final missions in Sebastian Sallow’s line of side quests that deal with the unforgivable curses, so it can only be started once you have finished most of Hogwarts Legacy’s main story.

Avada Kedavra is the last unforgivable curse you can learn, so if you haven’t already, you’ll need to know how to unlock Crucio and Imperio in Hogwarts Legacy first!

Here’s a step-by-step guide on how to learn Avada Kedavra in Hogwarts Legacy:

  • Complete all of the previous missions in Sebastian Sallow’s side quest line.
  • Once you have done this, you can return to the entrance of Feldcroft Catacomb to start the side quest In the Shadow of the Relic
Ominis Hogwarts Legacy
  • Follow Ominis into the catacomb and defeat the Inferi you find
    • To damage Inferi, you must first cast either Incendio or Confringo at them to burn them
  • Keep following Sebastian’s trail further into the catacomb
    • To get up to Sebastian, you will need to get some bones by opening compartments in the wall using Accio
    • Then use Wingardium Leviosa to create a staircase out of the bones that fell out
  • Now, walk up the bone stairs and talk to Sebastian
Sebastian Sallow In the Shadow of the Relic
  • Next, you will have to defeat Solomon Sallow
    • The best way to beat Solomon is by using Ancient Magic Throw to damage him with objects
  • After defeating Solomon, you need to follow Sebastian out of the catacomb

  • Once you have left the catacomb, talk to Sebastian Sallow
  • To learn Avada Kedavra, you need to select the following dialogue options:
    • Everyone should know that curse
    • “Yes please”
  • If you don’t select these options, you will not be able to learn Avada Kedavra

Now that you’ve unlocked Avada Kedavra in Hogwarts Legacy, you will be able to kill your enemies. But can you be evil in Hogwarts Legacy?

How Does Avada Kedavra Work in Hogwarts Legacy?

Avada Kedavra is the most powerful spell in Hogwarts Legacy, as it lets you instantly kill any standard enemy in one shot.

However, it has a very long cooldown, so make sure you use it against the most powerful enemy you’re fighting, like trolls. Additionally, Avada Kedavra doesn’t work against bosses, meaning you can’t insta-kill them!

If you’re going around using the killing curse, you will almost certainly want to look like an evil wizard too. Make sure to change the appearance of your gear in Hogwarts Legacy and find out how to unlock a Thestral flying mount to get that evil look!

Do NPCs Care if You Use Avada Kedavra in Hogwarts Legacy?

Despite it being unforgivable, NPCs don’t care if you use Avada Kedavra to kill your enemies in Hogwarts Legacy.

Whether you’re on a quest with Professor Fig or completing side missions with other students like Natsai Onai or Poppy Sweeting, you can freely use Avada Kedavra against whatever enemies you come up against!

Of course, you’re able to cast spells on enemies you find in the wizarding world, but you might want to cause chaos in Hogwarts too! If so, find out if you can cast spells on other students in Hogwarts Legacy!
