Mask of Malediction

Wondrous item, uncommon (requires attunement)

While wearing this mask, you are immune to being frightened. Additionally, you can use an action to change your appearance into a humanoid you’ve seen as with the disguise self spell, using Charisma as the spellcasting ability.

Familiar Faces. Whenever a creature within 30 feet of you makes an attack roll that targets only you, you can use a reaction to cause the mask to take on the appearance of a creature the attacker most fears or most loves. The attacker must make a Wisdom saving throw (DC 8 + your Charisma modifier + your proficiency bonus) or make the attack and any subsequent attacks against you on that turn with disadvantage. Whether it succeeds or fails, the creature is immune to this effect for the next 24 hours.

Anathema. This mask is cursed, and becoming attuned to it extends the curse on you. As long as you remain cursed, you are unwilling to take it off, and your sense of self becomes blurred. While attuned to it, you have disadvantage on Charisma saving throws.
