Erratic Combatant

You may not be known for your combat abilities, but you've learned to mimic some tactical maneuvers that can benefit others on the battlefield. On your turn, you can use a bonus action to feign a series of unorthodox maneuvers for up to 1 minute. While you are performing these maneuvers, you can move up to half your movement speed as a reaction. 

Unorthodox Feint. Choose a single hostile creature you can see within 30 feet. At any time after your performance begins, you can use a reaction to either impose disadvantage on the creature's next attack roll or grant an ally the ability to make an opportunity attack against the creature, adding your Charisma modifier to the roll (your choice).

Once you use this feature, you cannot use it again until you complete a short or long rest.
