As a Magic action while entirely within Dim Light or Darkness, you can expend 3 Focus Points to shroud yourself with shadows for 1 minute, until you have the Incapacitated condition, or until you end your turn in Bright Light. While shrouded by these shadows, you gain the following benefits.
Invisibility
You have the Invisible condition.
Partially Incorporeal
You can move through occupied spaces as if they were Difficult Terrain. If you end your turn in such a space, you are shunted to the last unoccupied space you were in.
Shadow Flurry
You can use your Flurry of Blows without expending any Focus Points.
