Martial Master

The martial prowess of trained warriors is legendary, especially that of swordsmen and archers. You have uncanny accuracy with attacks that rely on both precision as well as brute force. You gain the following benefits:

• Increase your Strength, or Dexterity score by 1, to a maximum of 20.
• Whenever you roll a 1 on the d20 for an attack roll using a weapon you are proficient with, you can choose to reroll the dice.

You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
