Beginning when you choose this style at 3rd level, you can spend 2 ki points as a reaction when you or an ally within 5 feet are targeted with a melee weapon attack. The attacking creature must succeed on a Dexterity saving throw (DC equal to your Ki Save DC). On a failed save, you choose a target within 5 feet of the attacking creature as the new target of its attack. The creature resolves its attack normally against the new target. You can choose to have the attack target no targets.
This art is exclusive to waterlacers. Moon style waterlacing focuses less on direct combat than many other lacing styles, instead focusing on reacting to what others do. The moon is the original waterlacer, pushing and pulling the tides. A moon style waterlacer attempts to emulate the moon, pushing the enemies down, and pulling allies up to achieve victory.
