Rachel combos from the Japanese wiki. This one drew my attention:

With A lotus
5B>5C>3C8D>236A(w)>5CC>214A>6A>236B>(frog)>6A>236A>6A>4B>OD>6A>BBL>236A(w) x2>BBL
Damage = 8k, seems to require one wind and lotus of course. I'm thinking lotus might only be needed to get the third pole, hopefully 3C8D>5CC>214A>6A>236B works by itself.
