Tristis' One Man Band

As an action, you can summon pairs of hands equal to your charisma modifier (minimum of one pair). For example, if you had a Charisma modifier of 2, you would summon 4 hands.

As a bonus action, these hands will obey commands you give them, such as playing a lyre or tapping on a surface in a rhythm. For the duration, anytime you make a charisma (performance) check in front of an audience you can make a charisma (performance) check for each set of hands using your charisma (performance) score. If these hands are using any of your instruments, you may add any bonuses as you would if you were playing the instrument. However, these hands can only play instruments in your possession. If you have no other instruments, they instead bang tables, chairs, pots or pans to create a catchy beat that symphonies well with what you're playing.

Using this spell allows you to perform as a one man band, earning an appropriate amount of money reflecting your performance as a band at the GM's discretion.
