Dual Blade weapon loadout questions

You might be able to do single-hit skills without a blade, not sure though. Those skills are actually based off your damage range rather than your weapon ranges. Multi-hit skills are a definite no though, since I think they work by taking from your damage range then multiplying by a modifier below 1 to get your single-weapon range for each weapon. I'm assuming that because when DBs attack monsters on wep cancel, it shows up as all misses.

Oh, except you can double stab I guess, lol.
