Welcome to the Persona 5 Strikers Guide for all the Personas needed for the 100% compendium. The game makes the fusions pretty easy this time around but some of them need to be defeated to be unlocked. Those personas will be written in red. Additionally, the final Persona Lucifer can only be crafted in the first Velvet Room in New Game +. To fuse all Personas you will need to be Level 90 at least and you will need a lot of Persona Points. Since Money is easier to get than Persona Point you can buy high-Level Personas and trash them for Persona Points instead.
