Your practice of martial arts gives you mastery of combat styles that use your Unarmed Strike and Monk weapons, which are the following:
• Simple Melee Weapons
• Martial Melee Weapons that have the Light property
You gain the following benefits while you are unarmed or wielding only Monk weapons and you aren't wearing armor or wielding a Shield.
Bonus Unarmed Strike. You can make an Unarmed Strike as a Bonus Action.
Martial Arts Die. You can roll 1d6 in place of the normal damage of your Unarmed Strike or Monk weapons. This increases to 1d8 at level 5, 1d10 at level 11, and 1d12 at level 17.
Dexterous Attacks. You can use your Dexterity modifier instead of your Strength modifier for the attack and damage rolls of your Unarmed Strikes and Monk weapons. In addition, when you use the Grapple or Shove option of your Unarmed Strike, you can use your Dexterity modifier instead of your Strength modifier to determine the save DC.
Your focus and martial training allow you to harness a well of extraordinary energy within yourself. This energy is represented by Focus Points. You have a number of points equal to your Monk level.
You can expend these points to enhance or fuel certain Monk features. You start knowing three such features: Flurry of Blows, Patient Defense, and Step of the Wind, each of which is detailed below.
When you expend a Focus Point, it is unavailable until you finish a Short or Long Rest, at the end of which you regain all your expended points.
The save DC for Focus Point abilities equals 8 plus your Wisdom modifier and Proficiency Bonus.
Flurry of Blows. You can expend 1 Focus Point to make two Unarmed Strikes as a Bonus Action.
Patient Defense. You can take the Disengage action as a Bonus Action. Alternatively, you can expend 1 Focus Point to take both the Disengage and the Dodge actions as a Bonus Action.
Step of the Wind. You can take the Dash action as a Bonus Action. Alternatively, you can expend 1 Focus Point to take both the Disengage and Dash actions as a Bonus Action, and your jump distance is doubled for the turn.
