Much like Bald Wu'ke and co., the other students threw themselves into setting up camps at their chosen locations. Amusingly, that became a chance to show off one's creativity in problem-solving and/or the size of their pockets.
A few had the same idea as Bald Wu'ke's team. They severed a few rocky spikes from the surroundings with their own techniques and built a makeshift fortress around their tents.
Some had managed to procure magical drilling equipment from the Alchemy Faculty prior to the Trial so that they could excavate a large cave out of a sufficiently large rock pillar — the idea was to make set their base one hundred-odd meter above ground much like a bird's nest. This allowed them to be safe from the reach of terrestrial wild beasts, but it also made going in and out of their base quite bothersome.
