Dual heavy weapon fighting

Through extraordinary strength and disciplined martial training, you have mastered the rare and brutal art of wielding two heavy weapons at once, overpowering foes with relentless force rather than finesse. You can engage in two-weapon fighting with heavy melee weapons that lack the special property (such as greatswords and greataxes), allowing you to make one additional off-hand attack as a bonus action when you take the Attack action while wielding a heavy weapon in each hand and while wielding two heavy weapons your speed is reduced by 5 feet until the start of your next turn due to the immense physical strain.
