Blade Spinner

Beauty and elegance, like steel wrapped in silk, the blade spinner delivers death to their foes as they move with equal parts poise and passion. The art of the blade spinner is that of a spinning whirlwind of brandished blades. Cutting this way and that—sometimes the same target twice and sometimes dispatching a duo of foes simultaneously—the blade spinner dances through the battlefield. Rarely one to shy away from a fight, the blade spinner wades into a battle like a fisher might ford a stream to find the perfect fishing hole.

Fighting style.

Beginning at 3rd level, you adopt a particular style of fighting as your specialty. Choose one of the following options. You can’t take a Fighting Style option more than once, even if you later get to choose again

Blind Fighting

You have blindsight with a range of 10 feet. Within that range, you can effectively see anything that isn’t
behind total cover, even if you’re blinded or in darkness. Moreover, you can see an invisible creature within that
range, unless the creature successfully hides from you.

Thrown Weapon Fighting

You can draw a weapon that has the thrown property as part of the attack you make with the weapon.
In addition, when you hit with a ranged attack using a thrown weapon, you gain a +2 bonus to the damage roll.

Two-Weapon Fighting

When you engage in two-weapon fighting, you can add your ability modifier to the damage of the second attack.

Calculated Risk

At 3rd level, you have learned to efficiently engage your enemies without committing everything to a single attack. When you hit an enemy and are able to add your sneak attack damage, you can choose to not use all of the sneak attack dice on your damage roll. If you choose to do so, if you hit an enemy later in the same turn you can use the unspent sneak attack dice.

Blade Dancer

At 3rd level, your practice and experience with your fluid movement while fighting has given you the grace
of a skilled dancer. When you make a Charisma (Performance) check to dance, you have advantage on the roll.

Whirling Death

At 9th level, the first time on your turn that you use Calculated Risk to reduce your sneak attack damage dice by at least 2d6, you add 1d6 damage to each damage roll that uses your sneak attack that turn.

Extra Attack

Beginning at 13th level, you can attack twice, instead of once, whenever you take the Attack action on your turn.
