Petty

Prerequisites: Charisma 13 or higher

You gain the following benefits:

Your Charisma score increases by 1, up to a maximum of 20.

You learn Vicious Mockery (if you do not already know it). Charisma is your spellcasting modifier for this spell.

When a creature within 30 feet fails an attack roll, you may cast Vicious Mockery on them as a reaction. You may use this a number of times equal to your proficiency. Because you're petty.
