Way of Shadows

Monks of the Way of Shadow follow a tradition that values stealth and subterfuge. These monks might be called ninjas or shadowdancers, and they serve as spies and assassins. Sometimes the members of a ninja monastery are family members, forming a clan sworn to secrecy about their arts and missions. Other monasteries are more like thieves’ guilds, hiring out their services to nobles, rich merchants, or anyone else who can pay their fees. Regardless of their methods, the heads of these monasteries expect the unquestioning obedience of their students.

Shadow Arts

Starting when you choose this tradition at 3rd level, you can use your ki to duplicate the effects of certain spells. As an action, you can spend 2 ki points to cast darkness, darkvision, pass without trace, or silence, without providing material components. Additionally, you gain the minor illusion cantrip if you don’t already know it.

Whenever you cast darkness you can see within the spell’s area when using it with this feature. While the spell persists, you can move its area of darkness to a space within 60 feet of you at the start of each of your turns. 

Shadow Step

At 6th level, you gain the ability to step from one shadow into another. When you are in dim light or darkness, as a bonus action you can teleport up to 60 feet to an unoccupied space you can see that is also in dim light or darkness. You then have advantage on the first melee attack you make before the end of the turn.

Improved Shadow Arts

At 6th level, your study of ki to duplicate the effects of certain spells furthes. As an action, you can spend 2 ki points to cast alter self, blur, or invisibility without providing material components.

Master of Shadows

Cloak of Shadows. When you are in an area of dim light or darkness, you can use your action to become invisible. You remain invisible until you make an attack, cast a spell, or are in an area of bright light.

Improved Shadow Step. When you use your Shadow Step, you can spend 1 ki point to remove the requirement that you must start and end in Dim Light or Darkness for that use of the feature. As part of this Bonus Action, you can make an Unarmed Strike immediately after the teleportation.
