I already mentioned that D attacks during OD are level G and not level 3. and meteor dive (2nd part of corona upper as I recall), and lightning arrow both bounce them off the ground during it. I think that's pretty neat, it's going to give probably pretty strong combos, damage and carry, probably, off of DP (during OD only), and off any starter I'm guessing too.
People just haven't posted any combos yet, but I'm sure they'll be figured out.
