Although Avada Kedavra has the longest cooldown time of all the unforgivable spells, it’s still worth unlocking because it can defeat any enemy, including bosses, with just one hit. This can make the final stages of the game much easier for players. Additionally, there are talents available that can make Avada Kedavra even more powerful than it already is.

One of the most significant decisions in Hogwarts Legacy is whether or not to use the three forbidden curses, including the Avada Kedavra. However, those who choose to use them will find that they are some of the strongest spells in the game that will definitely help you later on in the game.
So if you want to know how you can learn Avada Kedavra, dive into our article as we tell you what you need to do in order to learn the Dark Arts spell. Without any further ado, let’s start reading!
How Can You Learn Avada Kedavra in Hogwarts Legacy?
To learn how to use the spell Avada Kedavra, you need to go on a quest called “In the Shadow of the Relic”. First, speak to Ominis at the catacombs and be ready to use fire spells to fight against Inferi and spiders. As you progress, you’ll face a tough boss battle.

After defeating the boss, leave the catacombs. Talk to Sebastian and choose the second option, “Everyone should know that curse”. This will allow you to ask Sebastian to teach you Avada Kedavra by selecting “Yes, please”.
When Does Avada Kedavra Become Available in Hogwarts Legacy?
To learn the Avada Kedavra spell, you need to complete the quest Lodgok’s Loyalty, which is part of the main storyline that starts in the “Prepare for Your O.W.L.S” chapter. In addition, you will also need to finish a series of relationship sidequests with Sebastian Sallow, which begins with “In the Shadow of the Undercroft” and continues to “In the Shadow of the Relic”.

It’s worth noting that the quest to learn Avada Kedavra will only become available to players who have reached level 28. It’s also important that you pay close attention to the quest prompts when talking to Sebastian, as choosing the wrong option may prevent you from learning the spell.
What Story Choices Do I Need to Make So That Sebastian Teaches Me Avada Kedavra?
In the relationship quest “In the Shadow of Fate”, you’ll have a conversation with Ominis Gaunt where you’ll be presented with two options: “We should turn Sebastian in” and “We must not turn Sebastian in”. To learn Avada Kedavra later on, you need to select the second option. If you don’t, you won’t be able to learn any of the unforgivable spells, including Avada Kedavra.
