Quickstep

Your reflexes are honed. As a reaction, when an enemy makes a melee attack against you, before being hit, if your speed isn't 0, you can move 5 feet away from the foe without triggering opportunity attacks, potentially avoiding the attack if you leave its range.

You can use this invocation a number of times equal to your Charisma modifier (minimum of once), and you regain all expended uses when you finish a long rest.
