Given she’s primarily a support Magical Girl, I think the first ability would be better for her development. It can manifest in small ways in this encounter and become a skill she slowly works on developing, maybe even making it more offensive along the way.
That does sound good. I will probably have it show up as minor effects during the fight, maybe even just as much as her clearing up the storm completely before the girls vanquish the giant Pageless.

You, sir, are a horrible lurker. I CAN SEE YOU.
