Two-Handed Weapon Master

You have trained on the art of using oversized weapons in your favor instead of against you:

• You can wield two-handed weapons as one-handed, if you carry no other weapons in your off hand (you can still use a shield without any disadvantage);
• If the weapon has the versatile property, you can use the damage of the versatile as if you were using as one handed weapon;
• You can wield oversized weapons (up to one size larger) as a two-handed weapon, with disadvantage on the attack roll.
