Lute of Thunderous Thumping

Source: Dungeon Master's Guide (2024)

Weapon, Very Rare

This reinforced lute can be wielded as a magic Club that deals an extra 2d8 Thunder damage on a hit. Sing and Swing. If you’re a Bard, you can use your Charisma modifier instead of your Strength modifier when making a melee attack roll with the lute, provided you sing or hum while making the attack.
