Salamencetrainer34, TwinLiberate? It's kind of a weird ability. She and 1 ally have to be standing at the ends of a row or column of Dark Panels, then she has to successfully liberate it.
When that happens, the entire row/column between the two of them is liberated.
I think there might be a small bug that makes it not work properly. I think there's also another bug that lets you use it w/o Order Points, but I'm not sure
