A Sneaky Disguise

A pair of glasses with a large plastic nose, a bushy mustache, and eyebrows. 

While wearing this magical item, you are nearly unidentifiable to a creature type of the DM's choosing. A creature of this type must succeed on a DC20 insight check to discern you. You gain advantage on deception checks against the chosen creature type while wearing this magical item. However, you gain disadvantage on any charisma checks made against creatures that are not of the chosen creature type.

If you are attuned to this item, it gains a charge, enabling you to cast disguise self once per day. This resets at dawn.

Notes: Advantage: Deception, Disadvantage: Charisma Ability Checks
