How To Use Avada Kedavra
| Icon | |
 | |
| Cooldown | Effect |
About 90 sec. | Kills enemies instantly |
Avada Kedavra is a powerful spell that kills the opponent instantly but has a long cool time of 90 seconds. If you want to use it multiple times in battle, use Focus Potion to shorten its cooldown time.
Upgrade Avada Kedavra
| Talent Name | Avada Kedavra Mastery（Required：Lv22） |
|---|---|
| Effect | Killing an enemy with Avada Kedavra kills all cursed enemies. |
Avada Kedavra Mastery can be obtained by unlocking Dark Arts Talents. If you curse multiple enemies in advance, you can annihilate them all at once with Avada Kedavra.
Powerful Combo With Crucio
| Talents Required For The Combo | |
|---|---|
 Talent ① | Avada Kedavra Mastery（Required：Lv22） Killing an enemy with Avada Kedavra kills all cursed enemies at once |
 Talent ② | Crucio Mastery（Required：Lv16） Striking an enemy cursed by Crucio releases a projectile that curses a nearby enemy. |
- Cast Crucio
- Attack the enemy hit by Crucio to spread the curse
- Cast Avada Kedavra
- Drink Focus Potion (may not be necessary depending on how many enemies you have left)
- Repeat Step ① to ④
Crucio Mastery spreads the curse when attacking an enemy hit by Crucio. So first cast Crucio and attack that enemy. Spreading the curse would kill numerous enemies at once when you follow it up with Avada Kedavra.
Greatly Reduce Cooldown Time With Focus Potion
Drinking Focus Potion reduces the cooldown time of Avada Kedavra to approximately 30 seconds. If there are a lot of enemies left after the first Avada Kedavra, you can drink the Focus Potion and cast Avada Kedavra repeatedly.

It Does Not Work For Some Enemies
In the original story, there is no countermeasure against Avada Kedavra, but in the game, there are enemies immune to it.
You Can Try It In Dark Arts Battle Arena
The Dark Arts Battle Arena is available when you get the Dark Arts Pack DLC, in which you can cast Unforgivable Curse like Avada Kedavra in the dark Battle Arena. You can use Unforgivable Curses even if you haven't learned it yet, so try it out when you are nearby.
What Are The Advantages & Disadvantages？
Definitely The Most Powerful Class Spell
If you use the above combo with the powered up Talent and Crucio, you will be able to defeat a great range of enemies so we can say it might be the most powerful Spell. But there are some enemies that are not effected and the Cooldown time is long so it is a little hard to use.
