When redirecting attacks using your Deflect Attacks ability, add the ammount of damage you would have taken if you had not deflected the attack.
As a bonus action, you spend 5 Ki points and lower all of your physical defenses. Your AC drops to 10, and you automatically fail Strength, Dexterity, and Constitution saving throws to resist damage. Keep track of how many hit points you lose while in this state. This state ends when you make an attack or deal damage to a creature or after one minute. While in this state, you may use a reaction after taking damage to strike a creature with a melee weapon attack at advantage. The first time you deal damage after entering this state (including with the special reaction), you deal additional damage equal to two times the number of hit points you lost while in this state.
