Peony/Ceres/Siana/OPEN?
"Black magic," Peony answered quickly, "offensive. No curative or support spells." It was best to share her weaknesses now with her unfamiliar ally. "There are children still in the Tower." She trusted the white mage she had assigned to their evacuation, but they would not be gone yet.
The Firaga had not slowed these flan as much as she might have hoped; Blizzara followed, and out of the fading ice crystals, Siana emerged. Peony offered her a brief smile and nod in greeting -- no time for anything else -- before she began preparing her next spell.
She had never seen this variety of flan before, but that would not stop her. If not fire or ice, there would be something else, and she had had to work out elemental weaknesses more than once. These foes were weak to magic of some sort, and they would see them fall.
