Those who've played Persona 5/Royal or have a familiar understanding of P5 and its many spinoffs will recognize Hecate. She is Ann Takamaki's ultimate Persona, and she'll replace Carmen after reaching Rank 10 of the Lovers Confidant in P5/Royal. In Persona 3 Reload, Hecate won't appear in the compendium of the base game. If you want Hecate, you'll need to buy the Royal Set DLC, which comes with all the Phantom Thieves' second-tier Personas. Hecate in Persona 3 Reload still excels in Magic and Agi/Fire Abilities, and you'll want to equip her with the right Skills if you're serious about building her for mid/late-game.
