Are you sure about that? I took One-Handed Style because nowhere in the talent description or effect description does it mention no shields, just: Self+ 30% Grazes converted to Hits whith one-handed melee weapons."
There is already a massive bonus to accuracy while using a single one-handed weapon and no shield, so I don't see where it says the talent won't work with a shield.
Unfortunately I don't know how to look at the stat for Grazes converted to Hits, so I can't test it in the inventory screen like I can accuracy or defense bonuses.
I've seen differing opinions, but has anyone poked around in the assets or done enough ingame testing to know whether or not this is true?
If it doesn't work, I wasted one of my precious talents many hours of gameplay ago.
