Emperor's Amulet (大帝の護符, Taitei no gofu)? is a demon in Persona 5.
Theis an amulet with a True Cross and the supposed hair of Mary between the two large sapphires. It once belonged to the King of the Franks Charles I.
"Also known as Charlemagne's talisman, it is said to make its owner an emperor. In between the two gems is a piece of Jesus' cross and a hair of the Virgin Mary."
Emperor's Amulet is the fifth Persona of the Hanged Man Arcana and can be found in Shido's Palace and in the Sheriruth area of Mementos, from floors 7 to 13 (after clearing Shido's Palace). It is the only Treasure Demon with a title as a Shadow, being called the "Emperor's Talisman" before it is captured. Emperor's Amulet is the first Persona with access to the heavy single-target elemental and force skills, but as it cannot be used in battle, these must be applied to other Personas through fusion. When itemized using Electric Chair execution in the Velvet Room, Emperor's Amulet yields the Emperor's Amulet accessory, which increases the wearer's Endurance by 5 and grants them the Auto-Tarukaja skill.
