Dagger Expert Feat

You wield daggers with perfection and poise, able to use them fluidly in any situation.

Prerequisite: Proficiency with daggers

• Dagger Tricks. You can draw or stow any number of daggers during your turn. You have advantage on any ability check to conceal your daggers.
• Improved Critical. Your attacks with daggers score a critical hit on a roll of 19 or 20.
• Swift Stabbing. When you use two-weapon fighting using a dagger in both hands, you can take both attacks as part of the Attack action on your turn (without expending your bonus action). You can only make this attack once per turn.
