Dagger Frenzy

Increase your Strength or Dexterity by 1, to a maximum of 20.

Once on each of your turns, when you are wielding a Dagger in both of your hands, and you engage in two-weapon fighting with your offhand dagger, you can instead make two melee attacks.

When you attack with a dagger using Strength, your damage roll gains a bonus equal to your Dexterity modifier.
