Petty

They say spite is as good a motivator as any. Your pettiness manifests in more than just words as your need for conflict drives you.

You gain the following benefits:

• Increase your Charisma score by 1, to a maximum of 20.
• You learn the vicious mockery cantrip. You may cast this spell as a reaction when an enemy within 60ft of you misses an attack roll or saving throw. You can also cast these spells using spell slots you have of the appropriate level. Charisma is your spellcasting ability for this spell.

Because you're petty.
