Fury of the Whirlwind [Heroic Feat]

READ THIS: This is a Heroic Feat. It cannot be taken normally with an ASI or chosen at 1st level by any race. Instead, any character can take it instead of their class' level 20 capstone ability.

You have learned the True Way of combining martial fighting prowess with the pure, untamed force of the elements, to achieve perfect movement. You gain the following bonuses:

• You gain a flying speed of 30 feet. If you already have a flying speed, it increases by 30 feet.
• You can cast steel wind strike at 5th level once per short or long rest without using any resources. If you are capable of spellcasting, you also learn this spell and you can cast it with your normal spell slots.
• Whenever you hit a creature with a melee or ranged weapon attack, you can push it 5 feet in any direction.
