Whether for repentance or a method to train the inner spirit, monks training under the Way of the Shackled believe in one thing: a binding of the physical body to attain a more powerful spirit.
The Body is Weak
When you choose this tradition at 3rd level, you must keep yourself locked up in chains or be under another type of restriction on your body (such as lifting a heavy rock). Your movement speed is reduced by 10 feet and you have disadvantage on Dexterity (Acrobatics) checks while chained. If you find yourself unchained, you can no longer use your ki points.
But The Mind is Willing
At 3rd level, your body may be bound but your inner will is not. Your ki manifests physically in the Material Plane, acting as an almost-telekinetic force. You no longer need to use any part of your body for your unarmed attacks. You use your Wisdom modifier instead of your Dexterity modifier as your attack and damage bonus. In addition, you have the cantrip mage hand, and you may cast it without any components.
Starting at 6th level, your focus of the spirit advances at an accelerated pace. You treat yourself as two levels higher for the purposes of determining how many ki points you have.
Beginning at 10th level, your grasp on ki allows you to move through dimensions, unbothered by the restrictions of body. As a bonus action, you may spend 3 ki to cast the spell misty step on yourself.
Beginning at 17th level, you learn how to separate yourself from the chains of the Material Plane -- at least for a time. As an action, you may spend 4 ki to become incorporeal for 1 minute. You gain the following benefits while incorporeal:
