Way of the Swordsage
A master of martial maneuvers, the Swordsage is a physical adept — a blade wizard whose knowledge of the Sublime Way lets her unlock blinding speed and spiritual transcendence. Unlike other monks, the Swordsage trains with his weapon as well as his martial arts, practicing relentless discipline to hone her skills and perfect her combat maneuvers. The Masters of the Sublime way are a blur of deadly strikes on the battlefield, evidence of years of intensive training and meditation.
When you choose this path at 3rd level, you gain proficiency in martial weapons that do not have the Heavy property. Martial weapons are also treated as monk weapons for the purposes of monk class features.
Beginning at 3rd level, your training and discipline have taught you to channel your Ki into deadly combat maneuvers.
Maneuvers. You can prepare five maneuvers of your choice, which are detailed under “Maneuvers” in the Fighter class description. You may reselect these maneuvers each time you complete a long rest. You learn to prepare two additional maneuvers of your choice at 6th, 11th, and 17th level.
Many maneuvers enhance an attack in some way. You can use only one maneuver per attack. Once you have used a prepared maneuver it becomes unprepared and you may not use it again until you complete short or long rest. You may, however, use your action to meditate on a single maneuver to prepare it again.
Superiority Dice. Your superiority dice begin as d4s, and change as shown in the Martial Arts column of the Monk table. When you elect to use a maneuver, you may use a superiority die by expending 1 Ki point.
Saving Throws. When one of your maneuvers requires your target to make a saving throw to resist the maneuver’s effects, use your Ki save DC.
Quick to Act
By 6th level, you are exceptionally quick to act, and have advantage on initiative rolls.
At 11th level, you can strike an enemy within the span of a moment. As a bonus action, you can spend 2 Ki points to teleport up to 60 feet to a space that you can see adjacent to an enemy. You then have advantage on the first attack you make before the end of your turn.
By 17th level, you have mastered the Sublime Way and can strike with perfect form. You may now use two different maneuvers on a single attack, expending Ki points separately for each.
