Perfect Blade

You are an expert with a commonly underutilized kind of blade, the dagger. You gain the following benefits:

• Increase your Dexterity by 1, to a maximum of 20.
• When you make a ranged attack with a magic dagger by throwing it, the dagger returns to your hand immediately after the attack.
• When you make an attack with a dagger, the number you need to roll on the d20 to score a critical hit is expanded by an amount equal to half your proficiency bonus.
  For example, if you score a critical hit on a roll of 20 on the d20, and your proficiency bonus is +2, you instead score a critical hit on a roll of 19-20 on the d20.
  If you already have a similar benefit, this benefit still applies, and expands upon it. For example, if you already score a critical hit on a roll of 19-20 on the d20, and your proficiency bonus is +2, you instead score a critical hit on a roll of 18-20 on the d20.
• When you make a ranged attack by throwing a dagger, you can draw the dagger as part of the attack, and you can gain one of the following benefits for that attack:
  - Being within 5 feet of a hostile creature doesn't impose disadvantage on your attack roll.
  - Attacking at long range doesn't impose disadvantage on your attack roll.
