Increase dexterity by 1.
You gain the monk skill redirected force. This move is a reaction. When an opponent is in melee with you and makes an attack, you can spend 2 ki points to redirect the damage you have taken. You reduce the damage done to you by half and your opponent must make a dexterity saving throw, dc 10 + your dexterity modifier + your proficiency bonus. On a success the opponent takes half the total damage they inflicted, on failure they take the full damage they inflicted and are knocked back 15 feet from the redirected force of their blow. This reaction can be used even if you are reduced to 0 hit points. If halving the damage due to this reaction does not cause you to become unconscious, your redirected blow causes double damage. If your are still knocked unconscious by halving the damage, your opponent automatically succeeds on his saving throw. However if you have 2 more ki points in reserve you can make your opponent fail the save and take double damage while you fall unconscious.
