It's said that the first thing you'll notice about a Sky Dancer is their shadow, the second thing you'll notice is an arrow in your back. Sky Dancers are one with the wind, they have taken to the sky and conquered it. These rangers reach heights no one else can and scout out large areas with ease. They tend to be decisive and find taking the first action to be the best action. 

I am in the process of testing this and many of my other subclasses, and would appreciate any first alarms I can take care of before putting them in a session.

Sky Dancer Magic

Starting at 3rd level, you learn an additional spell when you reach certain levels in this class, as shown in the Sky Dancer Spells table. The spell counts as a ranger spell for you, but it doesn't count against the number of ranger spells you know.

Ranger Level	Spell
3rd	Expeditious Retreat
5th	Gust of Wind
9th	Haste
13th	Freedom of Movement
17th	Control Winds

Take to the Sky

At 3rd level, you gain the ability to take to the sky, gaining a flight speed of 30 ft. If you already have flight speed, gain an additional 10 feet of flight speed instead.

Favor of the Wind

Beginning at 3rd level, you and allies within 30 feet of you can add your wisdom modifier to initiative rolls and gain advantage on initiative rolls.

Dancing Motion

Starting at 7th level, when a hostile creature misses a melee attack against you, you may use your reaction to move up to half of your movement. This movement does not provoke opportunity attacks.

Aerial Maneuvers

At 11th level you gain one of the following features of your choice.

Strafe Attack

You can use your action to make a ranged attack against any number of creatures in a 30 ft line that you can see within your weapon’s range. You must have ammunition for each target, as normal, and you make a separate attack roll for each target.

Wind Blades

You can use your action to make a melee attack against any number of creatures in a 15 foot cone originating from you that you can see. You make seperate attack rolls for each target.

Wind at Our Back

Beginning at 15th level, Allies affected by Favor of the Wind have their speed increased by 30 for one turn. 

As a bonus action you can double the speed of allies within 30 feet of you for one turn. You can do this once per short rest.
