Master of Insults

Accustomed to the fine art of profanity and denigration, you gain the following benefits:

• You learn the Vicious Mockery cantrip, for which your spellcasting ability is Charisma. When you cast it, other creatures cannot hear the Verbal component of the spell and only hear the insults described in the spell description. The targeted creature perceives a headache during this time. As an action, it can make an Intelligence (Investigation) check  with a DC equal to 8+your proficiency bonus+your Charisma modifier. On a success, the creature realizes that you are the source of the headache and that it is being targeted by a spell.
• You gain proficiency in the Intimidation skill.
