Monastic Tradition: Way of the Deep Gaze

Some monks seek to open themselves to the flow of ki around and through all living things; through long study and meditation, they gradually develop mystical powers of heightened perception. These monks call their way of seeing the "Deep Gaze", and are notoriously close-lipped about what exactly it shows them, though those that have spent time among them remark often that they are frustratingly difficult to surprise.

Third Eye

Starting when you choose this tradition at 3rd level, you have learned to enter a state in which you have limited extrasensory perception. You can spend a bonus action to open your Third Eye for the next minute. At 9th level, you can open your Third Eye for 10 minutes at a time, and at 15th level you can keep it open indefinitely. While your Third Eye is open you can activate one of the following effects each turn. Keeping your Third Eye open requires concentration, and if it closes for any reason its active effects are lost and must be reactivated upon reopening the Eye.

When you make an attack with a monk weapon or unarmed strike, you can spend 1 ki point to gain advantage on that attack.

When you make a skill check you can spend your bonus action and 2 ki to gain advantage on that check.

When you are targeted by an attack you can spend your Reaction and 1 ki point to give that attack disadvantage.

When you are forced to make a saving throw in which you are proficient you can spend your Reaction and 2 ki points to gain advantage on that saving throw.

You can spend 1 ki point to become aware of the location of any hidden or invisible creature within 10 feet of you. At 10th level this range extends to 30 feet.

Essential Awareness

Starting at level 6, if you spend at least 1 minute observing or interacting with another creature outside combat while your Third Eye is open, you can learn certain information about its character compared to your own. The DM tells you if the creature's alignment is more Chaotic or Lawful and more Good or Evil than yours, and if they are generally hostile, friendly, or indifferent towards you.

In addition, if your Third Eye is open at the beginning of combat and you aren’t incapacitated, you can act normally on your first turn even if you are surprised.

Piercing Gaze

At 11th level, you can easily detect the weak points in the flow of your enemies' ki. When you deal damage with an attack from an unarmed strike or monk weapon you may change its damage type to psychic.

In addition, when your Third Eye is open, you can spend 3 ki points to gain Truesight until the end of your turn.

Creation Laid Bare

Starting at 17th level, once per long rest, you can spend 10 minutes in meditation with your Third Eye open to visions of many possible futures. After this meditation, you know the best path through a challenge you will face today. You can choose an encounter in which you will have advantage on all rolls, checks, and saves. The DM defines "encounter" for the purposes of this feature, ie. when the period during which you have advantage begins and ends. Your Third Eye must remain open for the duration of the encounter; if your Third Eye closes for any reason between the beginning and end of the encounter you loose the benefits of this feature and reopening the Eye will not regain them.
