Persona 5 Royal Persona Compendium & Fusion Guide

Why use our Persona 5 Royal database?
Our tool provides accurate data for the full Royal roster: endgame powerhouses like Yoshitsune, Satanael or Raoul sit alongside every regular persona. Persona Traits — the unique passive abilities every persona carries in Royal — are listed with their exact in-game effects.
Special Fusions in Persona 5 Royal
Certain personas cannot be obtained through standard two-persona fusions and require Special Fusion recipes with three or more specific ingredients. Classic examples include Alice (Belial + Nebiros), Ardha (Shiva + Parvati) and Yoshitsune (8 ingredients). Our compendium clearly indicates these recipes.
Treasure Demons
The nine treasure demons (Regent, Queen's Necklace, Stone of Scone, Koh-i-Noor, Orlov, Emperor's Amulet, Hope Diamond, Crystal Skull and Orichalcum) cannot be fused — they are recruited through negotiation in palaces and Mementos. When used as a fusion ingredient, each one shifts the result up or down its arcana list by a fixed offset.
Arcanas and the Velvet Room
Velvet Room fusions follow an Arcana chart: fusing two personas of given Arcanas yields a fixed result Arcana. The resulting level is the average of the parents plus one for different arcana (rounded down), or the closest level below the average plus one for same-arcana fusions. Knowing the chart lets you plan chains quickly.
