Cloud Dash

Your Vampiric blood allows you to change into a semi-ethereal state. As a bonus action, you can surround yourself in dark gray or black smoke. Your body becomes slightly transparent, and you can instantaneously dash (up to your movement speed) into one direction. You can pass through objects lower than 4 feet tall and you can also pass through creatures. Doing so leaves the creature disoriented. Getting damaged ends the spell early, and you return to your normal state after you end your turn
