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.
