Mastering the deadliest spell in the wizarding world is something many players seek when exploring Hogwarts Legacy. The infamous killing curse, Avada Kedavra, stands as one of the most powerful spells in the game, capable of eliminating any enemy with a single cast. But how exactly can you obtain this forbidden magic in Hogwarts Legacy? Let's dive into the complete process of unlocking this unforgivable curse in 2025.

Prerequisites for Learning Avada Kedavra in Hogwarts Legacy

Before you can even think about learning the killing curse, you'll need to meet several requirements. The game recommends reaching level 28 before attempting to unlock this powerful spell. This high level requirement reflects the advanced nature of the magic you're seeking to master.

Additionally, you must progress through specific quests:

• Complete the main story quest "Lodgok's Loyalty"

• Progress to the "Prepare for Your O.W.L.S" chapter

• Complete Sebastian Sallow's relationship quest "In the Shadow of Hope"

Only after meeting these prerequisites will you be able to begin the quest that ultimately teaches you Avada Kedavra.

The Critical Quest: "In the Shadow of the Relic"

The killing curse becomes available during Sebastian Sallow's relationship quest line, specifically in the mission titled "In the Shadow of the Relic". This quest represents a pivotal moment in your character's journey, testing their moral compass and willingness to delve into forbidden magic.

During this quest, you'll find yourself in a conversation with Sebastian outside a dungeon. Pay extremely close attention to the dialogue options, as selecting the wrong choice can permanently lock you out of learning Avada Kedavra. When prompted, you'll face these critical decisions:

1. First choice:

2. "No one should know that curse."

3. "Everyone should know that curse."

To learn Avada Kedavra, select "Everyone should know that curse".

1. Sebastian will then offer to teach you the killing curse, presenting another choice:

2. "Now is not the time."

3. "Yes please."

Select "Yes please" to begin learning Avada Kedavra.

Many players have reported accidentally selecting the wrong option here due to misunderstanding the dialogue's implications. As one player commented, "It's so frustrating that the option is 'no one should know that curse' versus 'everyone should learn it' when the protagonist then rambles about Sebastian's bravery. I had to reload because that came out of nowhere!"

Second Chance to Learn Avada Kedavra

What happens if you miss your opportunity to learn the killing curse? Fortunately, the game offers a second chance under specific circumstances. During Sebastian's next relationship quest, "In the Shadow of Fate," you'll have another critical choice when speaking with Ominis Gaunt:

• "We should turn Sebastian in."

• "We must not turn Sebastian in."

To maintain the possibility of learning Avada Kedavra later, you must choose "We must not turn Sebastian in."

After completing Sebastian's entire relationship quest line, you can meet him in the Undercroft where he'll offer to teach you any unforgivable curses you missed earlier. This serves as your backup plan if you initially declined to learn the killing curse.

Using Avada Kedavra in Combat

Once unlocked, Avada Kedavra becomes one of your most powerful combat tools in Hogwarts Legacy. The spell has the unique ability to defeat any enemy—including bosses—with a single hit. This makes it invaluable for challenging encounters, particularly in the later stages of the game.

However, this power comes with limitations:

• Avada Kedavra has the longest cooldown time of any spell

• It should be reserved for tough enemies like Trolls or bosses

• You'll need complementary offensive spells for regular enemies

Some talent upgrades can enhance Avada Kedavra's effectiveness, making it even more devastating against powerful foes. Strategically incorporating this spell into your combat rotation can dramatically simplify difficult battles.

Moral Implications and Companion Reactions

Interestingly, despite the dark nature of the unforgivable curses, Hogwarts Legacy doesn't feature a traditional morality system with direct consequences for using forbidden magic. However, your companions will react when you cast Avada Kedavra or other unforgivable curses.

Companions like Natsai, Ominis, and Amit will express disapproval when you resort to using the killing curse. Despite their reactions, these choices won't impact your relationships or alter the story's progression in any meaningful way.

Is Learning Avada Kedavra Worth It?

The question remains: should you pursue this forbidden knowledge in Hogwarts Legacy? From a purely gameplay perspective, Avada Kedavra offers tremendous combat advantages with its one-hit-kill capability. For players facing challenging encounters, particularly in the endgame content added in recent updates, having this spell can make a significant difference.

However, some players prefer to role-play characters who adhere to a stricter moral code. As one player noted, "I did this in my Ravenclaw run, in pursuit of knowledge. My Hufflepuff run will put Sebastian in his place." This highlights how the choice to learn Avada Kedavra can be part of your character's unique journey through the wizarding world.

Hogwarts Legacy how to get avada kedavra hogwarts legacy ultimately comes down to the type of witch or wizard you want to be. Will you embrace all forms of magic in your pursuit of power, or draw a line at the unforgivable? The choice, like so many in this rich magical world, remains yours to make.
