One Handed Weapon Master

You've learned to maneuver your weapon in a deadlier way

• When you score a critical hit with a one handed melee weapon you can add one die of the weapon's damage to the roll (not doubled).
• Before you make a melee attack with a one handed melee weapon that you are proficient with, you can choose to take a penalty to the attack roll equal to your proficiency bonus. If the attack hits, you add +twice your proficiency bonus to the attack's damage.
