Personas
Persona 5 has hundreds of Personas and a compendium to keep track of them, so a guide that simply lists more of them adds nothing. The pages in this bucket are here because each one answers a different question about the system: what to do with the one you start with, what to do with the ones you find, and what the whole apparatus is building towards.
The one you outgrow, and then do not
Arsene is the Fool Arcana Persona the game gives you in the first hour and expects you to fuse away within a few. Our page covers that, and then covers the thing most players miss: he can be brought back, and he can be awakened into Satanael, which turns the starter into an endgame Almighty and Curse platform.
That is the single best argument for registering Personas in the compendium before you consume them. Fusing something away is not permanent if you paid to record it first, which is also what the Mask Collector trophy in our mechanics guide quietly requires.
The ones you meet in the middle
Eligor is an Emperor Arcana Persona you can either fuse or take from a Mementos miniboss, which makes it a good illustration of the two supply lines running in parallel. Our page covers both routes plus its weaknesses, since you will most likely fight it before you own it.
Flauros is the Devil Arcana entry and it is a fusion target rather than a find: level 25, with a Tarukaja requirement in the recipe. It is the sort of Persona you make on the way to something else, which is exactly why knowing the recipe saves a wasted trip to the Velvet Room.
Ame no Uzume belongs to the Lovers Arcana and our page treats her as a skill-card problem rather than a stat problem: the reliable way to get the version you want is to fuse her with a Frei skill card, and there is a Dodge Psy route as well. If you have been ignoring skill cards, this is the page that shows what they are for.
The one everything else is for
Yoshitsune is the Tower Arcana Persona that most late-game builds are quietly aiming at, because of Hassou Tobi. Our page gives the fusion recipes step by step, its resistances, and the knowledge quiz answers that come up along the way.
It is also a good demonstration of how the two halves of Persona 5 connect. A Persona that far up the ladder is not something you stumble into; it is assembled from components you have been collecting, at a level you have to have reached, with an Arcana Boost from a Confidant you have been ranking up all year. The fusion guide covers the mechanics and the Fusion Alarm timing that makes the expensive attempts worth making.
The full list
For everything not covered above, our Personas list is the compendium in article form, sorted by Arcana from Fool through the whole deck, with each entry's base level and how to obtain it.
Sorting by Arcana is the right way round rather than an arbitrary choice, because Arcana is the axis that links this bucket to the rest of the game. Your Confidants are Arcana. Your fusion bonuses are Arcana. The Electric Chair executions in our items guide are listed by Arcana too. Once you know which cards you have people in, the compendium stops being a list of monsters and becomes a shopping list.
