Most Dagger damage comes from needing to flank your opponent and requires being in melee range. It also provides damage -only-. Magic Gunner has very good buff/status utility already, can attack from range, ignore Armor (for what it's worth), and have a method to attack while retreating.

They really do not need a passive that gives them more critical damage than daggers or more plain damage without a caveat. We could use more high-rarity Shotgun items with neat effects, but the shotgun itself is fine for its rarity.
