The greave appears to be missing it's partner. It otherwise looks like a mundane armored greave with the exception of teeth marks on the toe?

This single greave is seemingly missing it's match. The wearer of this greave can undo the last minute of conversation from the memories of it's listeners. In order to do this, the wearer needs to remove the greave and stick it in their mouth. This item requires attunement in order to function.

Notes: Bonus: Charisma Ability Checks, The wearer must meditate on the power of words and how they can harm for a day.
