Steel Whirlwind

The Steel Whirlwind archetype embodies the fierce warriors of the ancient past, using two weapons at once in unison with large sweeping and swirling strikes. Through intense focus and intense attacks, the steel whirlwind shreds through their foes.

Steel Whirlwind Magic

Starting at 3rd level, you learn an additional spell when you reach certain levels in this class, as shown in the Steel Whirlwind 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	Spells
3rd	jaws of the wolf, yield ground
5th	blur, butcher's glee
9th	curse of impending blades
13th	flashing blades
17th	steel wind strike

Slayer's Mark

Starting when you join this archetype at 3rd level, you gain the ability to mark a creature you hit with a melee attack. While marked, you gain a bonus to damage rolls against that creature equal to half your proficiency bonus, rounded up. This mark lasts until the end of your next turn, or until you mark a different creature.

Battleforged

Beginning at 7th level, while you are wielding a one-handed weapon in each hand and make an attack with both on your turn against a creature you have marked, you can take the dash action once as a free action.

Undaunted Stride

Starting when you reach 11th level, you are no longer effected by difficult terrain except for damage. In addition, any time you are in difficult terrain, you can use a reaction to gain a bonus to your AC or a Dexterity saving throw equal to your Wisdom modifier. You can use this feature a number of times equal to your Wisdom modifier, regaining all expended uses when you finish a short or long rest.

Twin-Blade Storm

Beginning at 15th level, you gain the ability to strike faster than a creature can follow. You can choose for your attacks to be against a contested Dexterity saving throw from the target rather than AC. When you hit with an attack in this way, you deal an additional amount of thunder damage equal to the damage die of your weapon.
