Armageddon is a Theurgy in Persona 3 Reload and Episode Aigis that you can obtain by registering Helel and Satan to your compendium. Learn how to get Armageddon here, and see the other requirements you need to meet to obtain it.

How to Get Armageddon

Register Helel and Satan

Armageddon is one of the strongest Theurgies the protagonist can learn in Persona 3 Reload. It's an ultimate spell that deals massive damage to all foes, allowing you to defeat them in one turn, at the cost of your own HP and SP.

To get Armageddon, you must register both Helel and Satan to your compendium. You need to reach at least level 88 and max out the Star Social Link to obtain both Personas required for this fusion skill.

Also Available in Episode Aigis

Armageddon is also one of Aigis' theurgies in Episode Aigis. Unlike in the base game, you only need to reach level 88+ to access Satan and Helel. You can do this by simply playing the game, defeating rare shadows, or beating the Reaper.

Complete Star Social Link to Unlock Helel

One of the requirements to get Armageddon is to unlock and register Helel, which only becomes available for fusion after completing Mamoru Hayase's Social Link. After completing this, you can fuse Alilat and Loki, or Metatron and Lilith to get Helel.

How to Fuse Helel

Reach Level 82+ to Fuse Satan

Satan is much easier to fuse, as you only need to reach level 82. Some combinations you can try are Lilith and Mara, or Horus and Lakshmi to get Satan.
