Savage Attacker (for the people)

Your strikes have become relentless, gaining the following benefits:

• Increase your Strength or Dexterity score by 1, to a maximum of 20.
• Once per turn when you roll damage for a melee weapon attack, you can reroll the weapon’s damage dice and use either total.
• Your melee weapon attacks critically hit on a roll of 19 or 20.
