Axe Mastery

You have specialized in the usage of axes, becoming better at their use in combat. While wielding an axe, you gain the following benefits:
⦁ Increase your Strength or Constitution score by 1, to a maximum of 20.
⦁ Critical hits deal one extra dice of damage of that weapon's type.
⦁ When making an attack, and you have extra attacks you can take, you can choose to not take those extra attacks and instead increase the damage of the attack you take by an extra dice of damage of your weapon for every attack not taken.
⦁ Attacks made with axes against objects deal double damage.
