Monks who follow in the Way of the Guarded Eye hold onto the notion that physical eyesight is a distraction and that true vision happens only in the mind. Because of this belief, many of the monks on this path tend to cover or harm their eyes in order to rely solely on the perception of their minds. Surely enough, they excel through this lack of vision—studying the aspects of ki and how it flows through them and around them.

Mind's Eye

Starting when you follow this monastic tradition at 3rd level, your physical eyes do not see what your mind can. You gain blindsight out to 30 ft. and are able to see any creature in that range that is not behind total cover or successfully hides from you. Spells such as darkness or being blinded have no effect on you and you can see invisible creatures (unless said creatures successfully hide from you).

The range on your blindsight becomes 60 ft. at 9th level.

Serene Sense

Starting at 6th level, you stand quietly and your heightened senses can see attacks coming before they are made. You can now spend 1 ki point to use the Dodge action as a reaction on your turn.

Flurry of Precision

Beginning at 11th level, your mental perception flows with your enemies' movements, finds a thread of weakness, and allows you to make a Flurry of Blows with extra damage.

On your turn, after you use the Attack action and hit a creature, you can spend 3 ki points and force the target to make a Dexterity saving throw. On a failed save, you unleash 2 Flurry of Blows attacks (a total of 4 unarmed strikes) on the targeted creature. On a successful save, the creature takes the normal Flurry of Blows damage, as it is able to protect the pressure points you target.

Ki Incarnation

Starting at 17th level, you maintain your monastic discipline to fight even when knocked down, by taking on a ki incarnation. When you drop down to 0 hit points, you are knocked unconscious, but the residual ki flowing through your body and mind allows you to push past your natural limits. 

You can expend any number of ki points that you have available and take the number as added hit points. Your unconscious ki incarnation displays itself as a colored, spectral outline around your body, while moving you of its own accord. Your ki incarnation takes your actions as you normally would, while you make your death saving throws as an additional action.

If your incarnation loses its hit points before you have finished your death saving throws, then it disappears and you continue with traditional death save rules.

In the instance that you fail three death saving throws, before your ki incarnation loses its hit points, the spectral outline of your ki incarnation fades and you collapse.
