Knife Juggler

The archetypal form of the Knife Juggler is that of the adrenaline rush that comes with a fine tuned flick of the wrist delivering your axe to a target as powerfully and accurately as any arrow shot from an archer’s longbow. It is the feeling of a flurry of knives meeting the battlefield with confidence, velocity, and grace. A Knife Juggler has trained extensively in homing his aim as well as his keen eyes and battlefield awareness, however he does not let this robotic knowledge get between him and enjoying the brawl at hand. 

(Technicalities: The archery fighting style also applies to throwing weapons as you are making a ranged attack, as well as the sharpshooter feat, basically as long as it’s something regarding a ranged attack, it counts.)

Bag of Tricks

At 3rd level you may draw or stow a weapon as a free action. 

Combat Flow

Granted when you choose this archetype at 3rd level, Combat Flow allows you to move up to ten feet in a direction of your choosing after successfully hitting an opponent with a thrown weapon attack. This movement can be foregone in favor of a long or high jump. None of these movement options provoke opportunity attacks. 

Interception

At 7th level you gain an almost preternatural understanding of the trajectories of flying objects. When you or a creature within your range is the target of a ranged weapon attack, you may use your reaction to attempt to intercept the attack with a weapon of your own. When you do so you must make an attack roll, succeeding on a result of equal to the enemy’s to-hit for that attack. On a success the missile is knocked out of the air harmlessly before reaching its intended target. 

Adaptable Salvo

At 10th level, you may treat any weapon which has the "light" property as if it has the "thrown" property. Light weapons thrown in this way have a range of (20/60). In addition, any weapon which originally has the thrown property, (not a light weapon which has been given the thrown property) has its range doubled. 

Superior Combat Flow

Starting at 15th level, when you use your Combat Flow class feature, you may move up to twenty feet. Alternatively you may long or high jump twice the amount you would normally be able to. (ignoring movement speed restrictions)

Superior Adaptable Salvo

At 15th level, Adaptable Salvo's benefits now extend to all weapons without the "heavy" tag, allowing you to treat them as weapons with the "thrown" modifier with a range of (20/60). 

Battle Climax

At 18th level, after hitting a single enemy consecutively with three attacks on the same turn, each additional hit on that enemy by you does increased damage as if it were a critical hit for the rest of the round.
