These unique Persona are procured by exploiting a specific weakness – which varies between treasure demons – and then negotiating. Nabbing your first treasure demon unlocks the A Phantom Thief’s Duty trophy.
More meant for fusion purposes to create every type of Persona than for actually using in battle, treasure demons also offer triple XP when sacrificed.
Discovering a Treasure Demon
Finding Stone Of Scone in Persona 5
One treasure demon that frequently gets missed is the Stone Of Scone (a reference to the Scottish “stone of destiny” used in coronations) – a level 20 Fortune arcana Persona found most frequently in the fourth Palace (Futuba).
Keep in mind that Persona above your level can’t be acquired (unless you have specific high rank Confidant abilities activated), so you’ll need to be level 20 to get Stone Of Scone.
Chronologically, the Stone Of Scone will be discovered after the level 15 Empress arcana Queen’s Necklace Persona and before the level 25 Priestess arcana Koh-i-Noor Persona.
Stone Of Scone is weak against Curse effects, but immune to all other attack forms. So have some Curse skills like Eiga and its successive iterations ready. Once you get him, the Stone has the following innate skills:
Agilao Bufula Zionga Garula Psio Freila Kouga Eiga
