Base Class: Monk
Trying to make shadow monk a bit better.
Blind Fighting
Having trained abundantly in both magical and non-magical darkness, you have developed the Blind Fighting fighting style.
Aura of Shadow
You have developed an aura of shadow, as darkness seems to follow you. The space you occupy and within 5ft of you counts as dim light in order to meet your ability requirements. It is NOT mechanically dim light.
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.
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.
Alternatively, when you spend 1 ki point to use Flurry of Blows, you may forgo one of the strikes to teleport up to 30 feet if you and your desired destination are both in dim light or darkness. You do not get advantage from this ability after teleporting this way.
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.
Opportunist
At 17th level, you can exploit a creature’s momentary distraction when it is hit by an attack. Whenever a creature within 5 feet of you is hit by an attack made by a creature other than you, you can use your reaction to make a melee attack against that creature.
