Martial Artist

You have trained in one, or several, weaponless combat techniques and have learned to assess the strengths and weaknesses of any who would face you in combat. Countless hours of training and practice have honed your body into a weapon, allowing your deadly Martial Arts strikes to deal as much damage as any weapon.
You gain the following benefits:

• Endless and focused training increase your Strength or Dexterity score by 1, to a maximum of 20.
• Martial Arts attacks use your Dexterity ability modifier.
• Martial Arts strikes deal 1d4 points of bludgeoning damage, which increases to 1d6 at 5th level, 1d8 at 11th level and 1d10 at 17th level.
• When making a Martial Arts attack on your turn, you can use your bonus action to make an additional Martial Arts attack or attempt to grapple with the target.
  If grappling with a target, you can use your Strength (Athletics) or Dexterity (Acrobatics) contested by the target's Strength (Athletics) or Dexterity (Acrobatics). If you succeed, you subject the target to the grappled condition.
