  • Gems can also be received as gifts from demon negotiations. If a demon is made both happy and eager, when asking for their spell card they will occasionally throw in a gemstone as well.

Aside from that, gemstones also have an effect when used in fusion. When fusing two spell cards in order to create a Persona, the Order of the spell cards determine the Arcana of the result Persona (e.g Night x Fairy = Magician; Snake x Drake = Priestess). After that, the Persona itself is determined by the following formula:



The resulting Persona is the one whose level is higher than the result of the equation. If a gemstone is added to the fusion, the order of the Persona may be reduced or raised by one or two. For example, should the player fuse Aello and Hannya the following would happen: their races are Flight and Brute which result in a Persona of the Empress Arcana. The Empress Personas are:

Vesta (6)
Mokosh (15)
Arianrhod (27)
Brigid (36)
Seioubo (44) °
Durga (57) °
Ishtar (65)
Kali (85) °

The ° symbol indicates a Persona that can only be fused with a Totem.

Inputting Aello and Hannya's levels in the formula results in 34, meaning that the Persona will be Brigid. The gemtones that influence the Empress Arcana and their effects are:

Emerald, Topaz or Turquoise (Order +2): Resulting Persona will not change since Durga needs a Totem to be fused.
Diamond, Sapphire, Pearl or Amethyst (Order +1): Resulting Persona will not change since Seioubo needs a Totem to be fused.
Ruby, Opal or Onyx (Order -1): Resulting Persona will change into Arianrhod.
Aquamarine or Moonstone (Order -2): Resulting Persona will change into Mokosh.
