Monks of the Way of the Dark Slayer train relentlessly with their weapons, to the point that the weapon becomes like an extension of the body. Founded on a mastery of sword fighting, the tradition has expanded to also utilize the ki of the monk for sudden bursts of speed and to project their energy as weapons at their foes.

A Dark Slayer sees their weapon as part of their being. To depart from the chosen weapon of the monk would be and unthinkable thing for a practitioner of this style of martial arts. While on their way of mastering their own ki and self a Dark Slayer also infuses their blade with their ki making it stronger as they also grow in power.

• Chosen Weapons. Choose 1 melee weapon to be your bound weapon. This weapon can be any simple or martial weapon that lacks the heavy and special properties. You gain proficiency with these weapons if you don't already have it. Weapons of the chosen types are monk weapons for you. Many of this tradition's features work only with your chosen weapons.

• Ki projection. You gain the ability to project your ki in the form of your chosen weapon and launch it at your enemies. You gain a new attack option that you can use with the Attack action. This special attack is a ranged spell attack with a range of 15 feet using your Wisdom for your hit and damage modifiers, you are also proficient with it. Its damage is necrotic, and its damage die is a d4. This die changes as you gain monk levels, as shown in the Martial Arts column of the Monk table.
