Ostentatious Rapier

Weapon (Rapier), Uncommon (Requires Attunement)
An elegant, bejeweled rapier which gleams brilliantly in the barest of light and produces a loud ring of steel when drawn from its ornate sheath.
While holding this magical blade, your voice is amplified and can be heard clearly from up to 300 feet away. You also have disadvantage on any Dexterity (Stealth) tests to hide. This weapon deals an extra 1d6 of Thunder damage on a hit.
If you have the Bardic Inspiration class feature, this damage is instead equal to your Bardic Inspiration Die. In addition, when you roll a Critical Hit, the creature you hit must make a Constitution saving throw against your Bard spell save DC or be Deafened for 1 hour.
