They glossed over it, but Harriet is the MVP of this arc, not only does she use her magic for MANY things like cutting trees down to build the shelters, giving everyone light and warmth at night and being the one to defeat the Orc, she also massively boosts moral with the underwater breathing thing, the classmates take turns going underwater and seeing how beautiful it is so the competition was more enjoyable for them.
She also gets an appreciation for the minor utility spells and starts practicing those more in the future
