Vampiric Exultation Vampire (Ixalan) As an action, you can transform the lower half of your body into an inky black vapor, allowing you to float through the air. While transformed, you have a flying speed of 30 feet. You can maintain this form for up to 10 minutes. Once you use this ability, you can't use it again until you finish a short or long rest.
