My 2 glass daggers don't work, they get no attack speed bonus, it's just slow... i tried ebony dagger + elven dagger, mixed all of them and it only works when I use the nightingale blade with a dagger, wtf? Otherwise it's way slower. It's as slow as it is at the start, what the heck? I have put 2 points into Dual Flurry (maxed) and uh... so.. yeah it doesn't work? cool, last time I checked it used to work and daggers are one handed weapons.
