True Flight (5e Feat)
From D&D Wiki
You gain a sliver of the true essence of flight, afforded perhaps by air elementals or other magical means, which allow you to bypass the typical physiological restraints to take to the skies. You gain the following benefits:
• As an action, you can activate True Flight. While concentrating (as if you where concentrating on a spell) you gain a flying speed of 20 feet, and you can hover. If you already have a flying speed, it increases by 20 feet. You can fly for 1 hour, being unable to do it again until you finish a long rest.
• You can take the Dash or Dodge actions as a bonus action while flying.
