I'm "gambling" that my regular 4 squads will be able to handle the regular combat. They're all multi-colored, but work squad synergy. First squad is my triggersquad with Fritillaria, which performs exceptionally well against batches of small pests. Second squad is a counter squad (my regular helper squad), which handles batches of small pests slightly less, but is great against bosses. Third squad is the debuff squad, which performs almost as good as the counter squad now, but still needs to be amped up. So far, the first squad managed to handle all whale encounters, but I'll see what happens on future maps.
