Amulet of enhancing mind and spirit

The amulet is made of silver with a mysterious gem inside of it. The inside of the gem looks like it contains a liquid when it is close to what it deems a worthy wielder. It enhances the wielder's capabilities by infusing its spirit with the wielder. The amulet seeks glory for both its wielder and itself. 

Sentience. The amulet is a sentient true neutral item with an Intelligence of 14, a Wisdom of 16, and a Charisma of 10. The amulet communicates by transmitting emotion to the creature carrying or wielding it, and it has hearing and normal vision out to a range of 60 feet. If the creature carrying or wielding it summons their visage or entire astral body the amulet's senses increases to 120 feet. The item seeks renown as the greatest spirit in the world, by establishing its user as a famous or notorious figure. 

Symbiotic Relationship. The amulet and the creature carrying or wielding it have established a symbiotic relationship. Once attuned the item cannot be removed from its wearer.

Personality. The amulet contains a calm spirit that turns vicious in the midst of battle. It prefers to solve problems head-on with glory and cares not for diplomatic solutions. If someone tries to wear the amulet that the spirit deems unworthy it will viciously take over the mind and body of that someone and wears those down. He prefers not to do this however since the spirit is afraid it will lose acclaim with the people. 

Dormant

The amulet grants the following benefits in its dormant state:

• Once per long rest, if the creature carrying or wielding this amulet has summoned their visage or entire astral body, the visage can let out a terrifying roar as a bonus action. All hostile creatures in a 10-foot radius of the visage must make a DC 12 Wisdom saving throw. On a fail, the creature becomes frightened for 1 minute. If the creature becomes frightened, on its next turn, it must use its full movement and move away from you by the safest available route, unless there is nowhere to move. At the end of the creature's turn, the creature can make a DC 12 Wisdom saving throw. On a successful save, the creature is no longer frightened.

If a creature's Wisdom score is reduced to 0 Wisdom by this feature the creature becomes unconscious. The bonus to the wearer's Wisdom score is lost on a short or long rest.
