This is the first archetype that I've designed and here is what I've done on it so far:
Mystic of the Hidden Way
The Mind’s Eye: A Mystic of the Hidden Way (or MotHW) uses his ki to repress his sight in order to gain other benefits. This blindness cannot be overridden by anything that would normally remove blindness (such as a wish spell). At 1st level the MotHW gains Uncanny Dodge (as the rogue ability with the same name), blindsense out to 15 ft., and the benefits of the Blind-Fight feat. At 5th level these benefits increase to blindsense out to 30 ft. and blindsight out to 15 ft. At 10th level the MotHW gains Improved Uncanny Dodge and the benefits of the Improved Blind-Fight feat. At 15th level the MotHW gains true seeing as a constant spell-like ability.
Guided Mind: At 1st level a MotHW may use his Wisdom modifier instead of his Strength modifier on attack and damage rolls with monk weapons and unarmed strikes. At 3rd level he may add his Wisdom modifier instead of his Dexterity modifier to his AC. This ability replaces maneuver training.
Ki Pool: A MotHW gains a ki pool at 1st level equal to 1 + his Wisdom modifier. At 4th level this increases to 3 + his monk level + his Wisdom modifier. This alters a monk’s normal ki pool ability.
Mind Over Matter: At 4th level a MotHW learns how to use his willpower rather than his body to strike down his enemies. Once per round, a MotHW may resolve an unarmed strike against his opponent’s touch AC by spending 1 ki point. At 8th level and 14th level he may use this ability an additional time each round. He must make this choice before the attack roll is made. At 20th level all of his unarmed strikes are resolved against his target’s touch AC. At 6th level he may choose to give all of his unarmed strikes an additional 5 feet of reach until the end of his turn by spending 1 ki point. The reach lasts until the start of his next turn at 12th level. This increases to an additional 10 feet of reach at 18th level. At 10th level he may make an unarmed strike as an immediate action (also resolved against touch AC) after hitting against a foe’s touch AC with his unarmed strike. If this attack hits, he adds the damage from the attack to the damage of the first unarmed strike for the purposes of damage reduction. At 16th level when he makes this additional unarmed strike, it is automatically treated as a critical threat (If the roll was a threat already, or the first attack was a threat, then increase the multiplier by 1). When confirmed, this strike multiplies the damage from the first attack as well as the damage from the second attack. Making this additional attack costs 2 ki points. This ability replaces slow fall.
(replace High Jump):
Clarity of Mind: At 13th level, a MotHW is immune to negative mind-affecting effects. This ability replaces diamond soul.
(replace Quivering Palm):
(replace Tongue of the Sun and Moon):
(replace Empty Body):
Mind is Matter: (replaces Perfect Self)
I am looking for feedback and suggestions for missing abilities.
