She's a decent healer particularly if you lack Ayaka or Lotus Fina as she can reraise, elemental support with four of the bar-aga spells, she's, innate 20% resist for all elements, 50% EVO magic and she's the first unit that uses the esper gauge to damage, Energy Blast apparently causes very decent damage
Her Limit burst is a combination of a curaja, massive Regen, a 74% All revive and an all 124% def and spr buff.
Her downsides are she doesn't carry Esunaga, or dual cast or curaja but she's a good all rounder, you can always pop a dualcast materia on her.
Her stats are decent, she's got MP refresh so all in all I think she's good to have.
Let me know how you get on with her
Edit: did another 10+1 thought fuck it use your last available 10+1 another off rainbow...Beatrix, like what th actual fuck, how can I get 4 rainbows in a day and not one of them is a banner unit rainbow??
Edit: because I'm trying not to double post daily rainbow...Dark Knight Cecil....are you fucking kidding me??? I've never been so lucky with a run of rainbows which is cool but the fact that none of them are an on banner rainbow is actually pissing me off.
