Finger Bone Brooch

Wondrous item, uncommon (requires attunement)

This macabre item consists of five long, straight finger bones affixed in the shape of a pentagram and attached to a thin silver chain. While wearing the brooch, you can use an action to speak its command word. For 1 minute, undead creatures have disadvantage on attack rolls against you, and they cannot charm, frighten, or possess you. Once used, this property of the brooch can’t be used again until the next dawn.
