You create a torrent of wind that circles around your feet, making you levitate.You gain a flying speed equal to you walking speed. You can then either:

• Throw an air spear dealing 1d10 piercing and 1d6 force damage. The target must roll a DEX save against your spell DC, the target is unaffected on a successful save.Any incapacitated target (caused by this spell) hit is instantly thrown back 10 ft and is no longer incapacitated.
• Incapacitate a target of your choice that you can see, the target makes a DEX save against your spell DC, the target is unaffected on a successful save. This effect lasts until the end of the spell.

At higher levels, the damage increase by 1d6 at 5th, 7th, 11th and 18th level.
