Kagejutsu
You have been trained in Kagejutsu, the way of the shadow. You are at home in the darkness, and at your most deadliest. You gain the following features.
Shadow Arts
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.
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.
Cloak of Shadows
By 11th level, you have learned to become one with the 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.
