Experience

After figuring that it was useless for them to rush towards the camp as they didn't know whether the benefits outweighed the dangers they would have to go through, their small team of three decided to come up with a proper plan to solve the most apparent issues at hand.

Those issues were their teamwork which was still far from perfect, their inexperience in fighting within specific environments, and times during the day, followed by their lack of knowledge.

There were probably a few more things they had to come up with, such as procuring food and drinking water, but that could be done quite easily.

By collecting some of the rainwater their biggest issue would be solved at once.

Food could be procured by killing beasts as well.

Hunting a few beasts to obtain meat was also what Bella proposed them to do, to begin with.
