Kensei Whip Master

Your training with the whip or chain allows you to use your weapon in masterful ways. When you hit a creature with a weapon attack, you can spend 1 Ki point to attempt one of the following maneuvers. If a maneuver you use requires your target to make a saving throw to resist the maneuver's effects, the saving throw DC equals 8 + your proficiency bonus + your Wisdom or Dexterity modifier (your choice).

Trip attack. You attempt to knock the target down. If the target is Large or smaller, it must make a Strength saving throw. On a failed save, you knock the target prone.

Disarming attack. You may attempt to disarm the target, forcing it to drop one item of your choice that it’s holding. The target must make a Strength saving throw. On a failed save, it drops the object you choose. The object lands at its feet. If it fails by 5 or more, the object may land at your feet instead, if you choose.

Pulling attack. You to attempt to pull the target closer to you. If the target is Large or smaller, it must make a Strength saving throw. On a failed save, you pull the target up to 10 feet closer to you.

Sweeping attack. You attempt to damage another creature with the same attack. Choose another creature within 5 feet of the original target and within your reach. If the original attack roll would hit the second creature, it takes damage equal to one half of the damage of the original attack. The damage is of the same type dealt by the original attack.
