Randel will likely spend his next turn healing Wilinlia, because we can definitely resurrect James in two turns, but she might die permanently in 4+ turns, and that would be more critical.

Jennifer moves towards Tessar's tower, simultaneously attacking anyone within range, ideally targeting the spearmen.
Caroline moves three spaces down and attacks the infantry with something, depending on their position. Ideally, if it doesn't hit our units and there's enough mana left for a resurrection – use Black Hole, but Disintegration is also an option.
