Petty

Your spite fuels your magic, allowing you to turn your enemies' failures into opportunities for humiliation.

• Ability Score Increase. Your Charisma score increases by 1, to a maximum of 20.
• Vicious Mockery. You learn the Vicious Mockery cantrip. Charisma is your spellcasting ability for this spell.
• Insult to Injury. When a creature you can see within 60 feet of you misses with an attack roll or fails a saving throw, you can cast Vicious Mockery against that creature as a Reaction. The spell must target the triggering creature, and you must be able to see and hear it.

You can use Insult to Injury a number of times equal to your Charisma modifier (minimum of once), and you regain all expended uses when you finish a Long Rest.
