She really doesn't.
Theoretically, we're getting the same as all the other Avatars: a miniclone of the whole.
But the Cait Sith that everyone is like "bluhbluhbluh we already know her abilities cause we fought her bluhbluhbluh" is NOT Cait Sith.
That was just a small piece of Her.
A fraction of the whole.
1/10th to be exact.
Number Ceithir to be even more exact.
So what would be correct in guessing is that we already have witness to Her phys BPs...
But Her magic BPs? Her 2hr?
Her this-is-my-version-of-the-merit-BP? (Holy Mist, Lunar Bay, Night Terror)
We know none of these things.
And we have no basis to base anything on about them either.
And what about Her wards?
What are they?
Chances are we can probably expect to see a sneak-invis-ga as one... if only for 1) Her pieces go sneak/invis constantly in WotG and 2) its one of the few buff effects that isn't in a Ward.
Divine Favor, Mewling Lullaby, and Erie Eye might be some of Her Wards... but AoE dispel? ANOTHER sleepga? Giving Amnesia to players?
I can see the Lullaby happening... with the TP=0 taken out...
And I can even see Divine Favor retaining it's full AoE dispel...
but something tells me that Erie Eye isn't gonna happen...
And this is only 3/10 BPs... Carbuncle is "special" in that he has virtually no perp cost and only 8 BPs + his 2hr...
But everyone else is sitting at 9+2hr.
(I'm ignoring the Celestials and just drawing from Fenrir and Diabolos, since chances are that She will be modeled similarly to them... even though the Celestials are also 9+2hr too.)
There's a LOT more to Her than that one fight you have with 1/10th of Her in WotG.
All we can really take from that is that one her phys BPs have been done from the beginning.
??? Holy won't probably be one. It *might* but chances are it will be a similar thing to Holy Mist.... or just an AoE light damage spell like Thunderspark... but who knows. Though I'd think a full 10/10 Cait Sith would have more firepower than a random thing.
