Bass
This specially crafted dwarven bass can magically shift in size from a bass guitar to a standup bass. As an action, you can press a concealed button on its side to transform it between forms. While in its enlarged standup form, the bass becomes nearly immovable. Until you or another creature uses an action to press the button again, the bass is magically anchored into the ground, and cannot be moved.
Thunder Strum. While holding the bass in either form, you can use an action to play a thunderous note. all creatures within 15 feet of you must make a constitution saving throw, with a DC equal to the result of your Performance check. On a failed save, a creature takes 2d6 thunder damage and is pushed 10 feet away from you. On a failed save, they take half that damage and are not moved. You may use this ability 3 times per long rest.
