Monks of the Way of the Chaste have given up their sight for a different way of seeing. They have mastered their remaining senses, able to hear, smell, feel, and taste far beyond the capabilities of most creatures.

Radar Sense

You have given up your sight to perfect your other senses. Starting when you choose this tradition at 3rd level, you lose your sight and cannot see or be given sight by magical means, but gain 30 ft. of blindsight. You gain proficiency in Perception, and gain advantage on any Wisdom (Perception) check that doesn't rely on sight. You can no longer read with sight, and roll with disadvantage on any saves that attack your other senses, such as loud noises, foul odors, ect. If you are deafened, your blindsight range is reduced to 0 ft. for the duration.

Enhanced Senses

At 6th level, you have trained your senses even further. You gain the ability to detect poisons from their scent or taste, and can track creatures based on their scent. You also gain advantage on Wisdom (Insight) checks when determining if a creature with a heartbeat is lying. You also gain proficiency in Acrobatics, and if you fail a Dexterity (Acrobatics) check to avoid falling or maintain your balance, you can spend 1 ki to roll again, and must use the result of this second roll.

Rebound Attacks

Beginning at 11th level, your awareness of the battlefield is unmatched. When attacking with a thrown weapon you're proficient with, you can ignore cover by throwing the weapon at a nearby surface, causing it to bounce off and strike the target creature. You can use the same weapon for every attack you make this turn, as long as each target is within 10 ft. of the last. The weapon ricochets off of nearby surfaces and creatures, avoiding obstacles and bouncing from enemy to enemy.  When you use this feature, as a bonus action you may spend two ki to make up to two additional attacks and have the weapon return to your hand. You cannot attack the same creature twice with this feature.

Perfected Senses

At 17th level, the way you traverse through life has changed you. When making a Wisdom (Perception) check that doesn't rely on sight, you add double your Proficiency Bonus to the check, instead of your normal Proficiency Bonus, and you can no longer be surprised or frightened. The range of your blindsight increases by 10 ft., and you gain tremorsense with a range of 60 ft. As an action, you can spend 1 ki point to double the range of both these senses for 1 minute. If you take damage during this time, you must make a Constitution saving throw. On a failure, you lose the extended range.
