Fake cast

Pick a spell that you know of, using the same casting time as that spell you can mimic the somatic and verbal components of the spell tricking all creatures that can sense you believe you are casting the spell. A tricked creature can make a Intelligence saving throw (DC 8 plus Charisma and your Proficiency Bonus), seeing through the trick on a successful saving throw.
