Shadow Illusion
At 13th level, you learn to shape shadows to your will, and create a shadowy clone of yourself. As an action, you create a perfect illusion of yourself that lasts for 1 minute, or until you lose your concentration (as if you were concentrating on a spell). The illusion appears in an unoccupied space that you can see within 30 feet of you. It must be created in an area of dim light or darkness. It can move into the light after that, but if it is in bright light at the end of your turn, it vanishes. Whenever you move, you may move the clone a number of feet equal to your speed to a space you can see, but it must remain within 120 feet of you.
For the duration, you can use a Bonus Action to swap places with your Shadow Illusion.
Once your Illusion disappears, you cannot summon it again until you finish a Short Rest.
Improved Dance of Shadows
At 17th level, your shadowy performances become even more deadly, as you waltz with darkness itself, and shadows envelope your blades. While your Dance of Shadows feature applies to a creature, your reach with Melee Weapon Attacks is increased by 10 feet, you gain a bonus to AC equal to your Charisma Modifier, and your speed is increased by 10 feet.
