Maybe Rand and Azarl can go to the West and clear the laser tower and guard. And Xavier goes to the center and attack guards with Rianna and Galder hopefully cleaving them all dead. While Haron and Con attack one Pikeman and Dak and Gallador another. That way we might clear the whole center. And then next round we can pursue the Nom and take care of the additional guards.
Btw, does Relle have an extra move or what is she doing?
