While many would succumb to the crown's mysterious power, you were seemingly reborn from it. Peculiar... 

Upon placing the crown on your head, your physical body falls limp to the ground and is unconscious. You then take on your spiritual form. In this form, you gain the following abilities:

Incorporeal Movement. The spirit can move through other creatures and objects as if they were difficult terrain. The physical body takes 5 (1d10) force damage if the spirit ends its turn inside an object.

Impenetrable Forces. The spirit cannot take damage or have its hit points reduced below 0.

Horrifying Visage. If the spirit is the singular target of an attack, the attacker must succeed on a DC 13 saving throw or be frightened for one minute. If the save fails by 5 or more, the target also ages 1d4 x 10 years. A frightened target can repeat the saving throw at the end of each of its turns, ending the frightened condition on itself on a success. If a target's saving throw is successful or the effect ends for it, the target is immune to this spirit's Horrifying Visage for the next 24 hours. The aging effect can be reversed with a greater restoration spell, but only within 24 hours of it occurring.

Crystal Blue Persuasion. The spirit has advantage on Intimidation checks. 

If the wearer's physical body drops to 0 hit points, the wearer automatically fails all death saving throws and the spirit form ceases to exist.

If the crown is removed while in your spiritual form, your spiritual form ceases to exist and you return to your physical body and are prone.
