Are there any unexpected problems with this Homebrew feat?


I (the DM) am considering the following feat, after a player asked about an alternative way to use Two Weapon Fighting.

Knife Fighter

You are especially skilled at the use of the Dagger, gaining the following benefits:

  • You gain a +1 bonus to AC while you are wielding a dagger.

  • You can use two-weapon fighting even when the one-handed melee weapon you attack with is not light, so long as the bonus attack is made with a dagger.

  • You can additionally draw or stow a dagger when you would normally be able to draw or stow any one-handed weapon.

  • You do an additional 2 damage when you hit with a dagger.

Obviously, the most direct comparison is to Dual Weilder. The intent of the feat is to allow a character to wield a Rapier and Dagger, or a pair of daggers and not be at a significant mechanical disadvantage over the Dual Wielder with a pair of rapiers.

Advantages I see compared to the Dual Wielder:

  • Marginally less expensive/heavy.
  • More concealable.

Disadvantages:

  • Additional damage is not multiplied on a critical hit.

Are there additional issues I have missed that would make this feat better or worse than Dual Wielder? Are the issues (above or otherwise) likely to cause problems or have interactions I have not forseen?
