Mask of the Silver Raven (Patreon)

Wondrous item, uncommon

This silvery carnival mask has black raven feathers around it and hidden divination runes. While wearing this mask, people will have disadvantage in perception and investigation checks to recognize you.

Mimicry. After spending at least 1 minute watching and hearing someone talk, you can perfectly mimic the target's voice and speech. You gain advantage in charisma checks to impersonate the target as long as they rely on hearing.

Trick of the word. Once a day, when you roll a charisma check, you can attempt to change the perception of the things you just said magically. You can reroll the die and must use the new roll.
