Wondrous item, uncommon (requires attunement by a humanoid)
The
Circlet of Human Perfection
transforms its attuned wearer into an attractive human of average height and weight. The circlet chooses the physical characteristics of the form, such as age, gender, skin color, hair color, and voice. Except for size, the wearer's statistics and racial traits don't change, nor do items worn or carried by the wearer.
Removing the circlet ends the effect.
