Rangers that use the whirlwind blades fighting style.

Whirlwind Stance

As a bonus action you begin channeling elemental winds around you. Your turn immediately ends as you channel the wind around you until your next turn, the channel ends if you are incapacitated, use a reaction, are forcibly moved or knocked prone. If you successfully channel this ability until the beginning of your next turn you gain the effects of the disengage action and if you take the attack action this turn you may make another attack with a bladed melee weapon as part of that action.

Whirlwind Magic

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

Gale Force

At 7th level, when you enter your whirlwind stance ranged weapon attacks against you have disadvantage while you channel your stance. Additionally when you complete the channel you also gain the effects of the dash action as well as the other effects.

Cyclonic Strikes

At 11th level, hitting an enemy with a weapon attack marks them until the end of your turn. Hitting a marked enemy with a weapon attack consumes the mark and deals 1d6 force damage to the enemy and all enemy creatures within 5ft of the damaged creature must make a strength saving throw or be knocked back 5ft.

Cyclonic Burst

At 15th level, when you are under the effects of Whirlwind Stance you may use a bonus action to enter the Cyclone stance. Until the end of your turn whenever you damage a creature with a melee weapon attack for the first time this turn you may immediately take an additional melee weapon attack against that creature for free.
