I'm looking to optimize her damage output - and more specifically on her offhand, which does NOT get her Str bonus. Since it's an actual damage roll, however, pretty much all other modifiers will apply. Her current build is playing around with Light Blades, but I'm not sold on that idea. I *am* sold on the +3 Jagged (whatever). Expanded critical range plays nicely with the barbarian's Rampage class feature. Plus, ongoing damage.
So ... light blades or heavy blades? Feat and gear suggestions are also welcome.
