Inspired by VR's post in the general yesterday, I managed to increase the damage on the FC 214B combos with the same enders.
FC 214B Dash 5B j.C xx j.214B 5B 5C j.BB jB j.2A (3309)
FC 214B Dash 5B j.C xx j.214B 5B 2B j.C xx j.214B 2B j.C xx j.214A (3697, w/ Zio 4608, w/ Cross Slash 4987)
I couldn't figure out a better way to use the resources his last combo used.
