Power Stance
When you take the attack action with a heavy melee weapon you are proficient with on your turn, you can make a special attack in place of any of attack with the weapon, a power attack:
Power Attack. You do not add your proficiency bonus to the weapon’s attack roll. On a hit, you add your proficiency bonus to the weapons damage roll instead. If you wield the weapon in two hands, you add twice your proficiency bonus to the damage roll instead.
