Base Class: Monk
Control the shadows
Embracing the shadows
As a Bonus Action, you can become invisible for 1d4 turns
Improved Shadow Step
You can draw on your connection to shadow to empower your teleportation. When you use your Shadow Step, you can spend 1 Focus 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.
Cloak of Shadows
As a Bonus Action while entirely within Dim Light or Darkness, you can spend 3 Focus Points to shroud yourself with magical darkness for 1 minute, until you have the Incapacitated condition, or until you end your turn in Bright Light. While shrouded in darkness, you gain the following benefits:
Invisibility. You have the Invisible condition.
Partially Incorporeal. You can move through creatures and objects as if they were difficult terrain, but you take 1d10 Force damage if you end your turn inside a creature or an object.
Shadow Flurry. You can use your Flurry of Blows without spending any Focus Points.
