Treasure Demon

Rare Persona is an umbrella term for a collection of Personas only appear in Persona 5 which cannot be equipped for combat but can be used in fusion. Fusion with rare Personas is very similar to Element race demons in the traditional Shin Megami Tensei series in that a rare Persona will change another ingredient Persona in fusion into another Persona of the same Arcana either 1 rank up or down, this allows a simpler way to complete the Persona Compendium or deal with an issue when DLC Personas get in the way of the usual fusion recipe.

The difference with Element demons is that rare Personas cannot be created via fusion but can only be negotiated and obtained in the dungeon (Element demons on the other hands never respond to negotiation). When opening a shinny treasure chest, there is a small chance the shadow of a rare Persona will pop up instead and attempt to escape from the player. When engaged in battle, they will remain stumbled for few turns but quickly flee. Knocking it down and ask it to join will obtain the Persona instantly. Because many of these rare Personas have a wide range of elemental resistances, it is recommended to rank up Shinya Oda's Confidant to unlock the skill "Knock-down Shot" which guarantees knocking down the target regardless of resistance in exchange of firing all remaining bullets.

All rare Personas are modeled after luxurious jewelries instead of mythological figures.
