Persona 3 Reloadbrings in Fusion Spells but now makes them the Protagonist’sTheurgyskills. Theurgy Skills are an ultimate attack performed by a party member, dealing incredible amounts of damage with energy that is built up over multiple turns and used at the players' discretion.
For the Protagonist, two Personas will be summoned to perform an incredibly powerful ability. These Personas only need to be unlocked in the Compendium and not actively equipped, giving players a wide array ofFusion Spellsto choose from when needed. The Protagonist’s ultimate Theurgy Skill is Armageddon, which is able to end almost any fight in a single turn; here’s how to get it.

How To Get Armageddon
To unlock the Armageddon Theurgy Skill,players will need to have summonedSatanandHelel.Satan is the lower level and easier Personas to obtain, with a go-to method for fusing it being Houou of the Star Arcana and a starting level of 70, with Ananta of the Aeon Arcana and a starting level of 73. Satan’s starting level is 82, with the player needing to be that level or at least 77 with the Sun Major Arcana card active to fuse it.
Helel can be a bit tricker as its starting level is 88. To fuse Helel,players must have completed theStar Social link.One method for fusing Helel is by fusing a Mother Harlot of the Empress Arcana and a starting level of 77 with Susano-o of the Fool social link and a starting level of 77. Be sure to carefully select skills when fusing both of these Personas, as they are some of the best in the game and should be used against the final boss.

How To Use Armageddon
After fusing both Satan and Helel, and each being in the Compendium, Elizabeth informs the player that they have awoken to a new power. Armageddon is used like any other Theurgy butdeals 9,999 Almighty damage to all enemies.This is enough to one-shotthe Reaper,making grinding the last few levels to reach 99 a breeze with a charged-up Thuergy bar. The major downside to this skill is that itleaves the Protagonist with only 1 HP and 1 SP.This is deadly if an enemy somehow survives in combat, and it will be a drain on SP restoration items in Tartarus if used too often.
