The winds carry you with ease. You gain a magical flying speed of 18 meters. As an action, you can reduce your flying speed to 9 meters for 1 hour and choose a number of creatures within 9 meters of you equal to 3 + your Charisma. The chosen creatures gain a magical flying speed of 9 meters for 1 hour.
Once you reduce your flying speed in this way, you can’t do so again until you finish a short or long rest.
