I pretty much stayed away from daggers on my third playthrough. I only used one on Maria, and that was the Assassin's Dagger. Otherwise I had a Blade of the Lord on Andrew, a Sword and Shield Axe on Alexander, and a Darkness Rod on Laura. Big difference compared to testing when daggers had enemy weaknesses, and it was pretty much 4 golden daggers. :)
Didn't notice he fiddled a bit with the agi bonuses, but oh well. They're still pretty handy.
