the background gradients lead into another skill. In order: Spinning Edge > Gust Slash > Dancing Edge> Multilate > Aeolean Edge > Shadow Fang.

Seems like a coincidence int eh grandscheme of the job. But the first 2 icosn matched the fists steps of the combo. the third icon is a possible 3rd step, which in turn leads into the DoT skills, which ends the "spectrum"

What do you think?
