Unbelievable. I was hoping it wasn't true but MAN these are the dullest effects they could have picked.
And what new abilities do we get? I'm so glad you asked!

A 600p followup to divination, and 10% mit addition to neutral sect. That's... that's it. A couple potency increases, new vfx for asp. helios, and a 3rd ED charge. That's it. Enjoy the next 3 years of astrologian. I'm just in awe at how much square enix doesn't want people to actually think while playing this game. We get refluffed versions of skills we already had as cards, some flashy vfx, a 10% mit and a 2min CD single use dps spell. Please look forward to it.
