Maybe i'm spoiled by P4G but is there no way to get a persona back after it's been fused besides hunting for it in Tartarus?

Pretty sure you unlock the compendium a few days in?

Never played P3P though, so maybe it takes longer or has different requirements.

Yeah you unlock the compendium on your second trip to Tartarus.

If they didn't change it from the PS2 version you don't get access to the compendium until after the second full moon.

You get it after the first major boss (not the tutorial boss) second full moon. What ptiew said

@petiew: Thanks! I was starting to wonder why that feature wouldn't be in Persona game.

I never got into stuff like Pokemon but i love collecting new Personas and adding them to the book.
