Improved Critical

You have an uncanny aim with attacks that rely on precision and are able to strike brutal blows while seizing the advantage of your attack.

• Increase your Dexterity, Intelligence, Wisdom, or Charisma score by 1, to a maximum of 20.

• Whenever you have an advantage on an attack roll your Critical Threat Range increase by the following chart. If your Critical range was already increased from another function this feat will stack with that as well.
  • 20 becomes 19-20
  • 19-20 becomes 17-20
  • 17-20 becomes 15- 20
• Additionally when you roll a critical, if you roll max damage on your initial double damage roll you may roll an additional damage die and apply that to the total.
