Peony/Ceres/Siana/OPEN?
"I didn't bring restoratives," Peony called out. "There was no time." She had to hope they would manage without them, though Siana's untimely blindness was ill luck. Perhaps the knight had Esuna in her arsenal -- along with Shell -- but all Peony could do was make note of Siana's location and attempt to cast well clear of her.
Her next attempt at a spell was a gamble -- she cast wide, knowing that otherwise she would compromise the others' footing. The earth shook with Quakera -- and the smaller flan in the vicinity shuddered and melted.
"Earth," she called out, in case the others had some abilities at their disposal. The larger flan did not seem similarly affected, but there were fewer of them -- if the smaller beasts could be dispersed, then this fight would become much easier.
