Deflect Missiles
You can use your Reaction to deflect or catch the missile when you are hit by a ranged weapon Attack.
When you do so, the damage you take from the Attack is reduced by 1d 10 + your Dexterity modifier + your monk level.
If you reduce the damage to 0, you can catch the missile if it is small enough for you to hold in one hand and you have at least one hand free.
If you catch a missile in this way, you can spend 1 ki point to make a ranged Attack (range 20 feet/60 feet) with the weapon or piece of Ammunition you just caught,
as part of the same Reaction. You make this Attack with proficiency, regardless of your weapon Proficiencies, and the missile counts as a monk weapon for the Attack.
Slow Fall
You can use your Reaction when you fall to reduce any Falling damage you take by an amount equal to five times your monk level.
Ki-Empowered Strikes
Starting at 6th level, your unarmed strikes count as magical for the purpose of overcoming Resistance and immunity to nonmagical attacks and damage.
Stillness of Mind
Starting at 7th level, you can use your action to end one Effect on yourself that is causing you to be Charmed or Frightened.
Evasion
Your instinctive agility lets you dodge out of the way of certain area Effects, such as a blue dragon's lightning breath or a Fireball spell.
When you are subjected to an Effect that allows you to make a Dexterity saving throw to take only half damage, you instead take no damage if you succeed on the saving throw, and only half damage if you fail.
