Melee Dagger Mastery

You have mastered melee combat with daggers, increasing your precision and speed, but the daggers never leave your hands. You gain the following:

• When making melee attacks with daggers, you deal 1d6 piercing damage and also increase your Dexterity score by 1, to a maximum of 20.
• When invisible or successfully hidden, your critical hit range with daggers increases by one integer, allowing you to critically strike with attack rolls of 19 or 20.
• While wielding a dagger in each hand, you can make a bonus action attack with a dagger. This will benefit from your ability modifier.
• You are unable to make any ranged attacks with a dagger.
