Superior Weapon Master

You've extensively trained with your weapons, allowing you to expertly handle them. You gain the following benefits:

• When you would attack with a weapon with which you are proficient with, your weapon attacks score a critical hit on a roll of 19 or 20.
• If you would miss a weapon attack due to having disadvantage where you would normally hit, you can ignore the effects of having disadvantage against that attack, however the rules of having disadvantage still apply, such as with Sneak Attack. You can use this trait once per short or long rest.
