Way of the Mastigophora

The mastigophorai are whip-bearers who specialize in flogging opponents. They perform crowd control duties at public functions and also as a form of public punishment when an athlete or coach breaks the rules at a competition.

Their expertise extends to all flexible weapons, including spiked chains.

Whipmaster

When you choose this tradition at 3rd level, you are proficient in whips and spiked chains and are monk weapons for you. Additionally, you can spend 1 ki point to add your Martial Arts die as bonus to the following skills:

Athletics (to grab something at a distance), Acrobatics (to prevent a fall or catch someone falling), Sleight of Hand (to remove an object from a person), Animal Handling (whipping the animal) and Intimidation (to terrify someone with the whip).

Whiplash

At 6th level, your whip or chain is considered magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage. When you hit a target with your chosen weapon, you can spend 1 ki point to cause the weapon to deal extra damage to the target equal to your Martial Arts die. You can use this feature only once on each of your turns.

Empower Whip

At 11th level, you gain the ability to augment your weapons further with your ki. As a bonus action, you can expend up to 3 ki points to grant one whip you touch a bonus to attack and damage rolls when you attack with it.

The bonus equals the number of ki points you spent. This bonus lasts for 1 minute or until you use this feature again.

This feature has no effect on a magic weapon that already has a bonus to attack and damage rolls.

Whip Strike

At 17th level, your mastery of weapons grants you extraordinary accuracy. If you miss with an attack roll using a monk weapon on your turn, you can reroll it. You can use this feature only once on each of your turns.
