Since the group decided to spend a day at the camp, Seth had enough time to experiment. His experiments were mostly unsuccessful. However, he had seen a sliver of hope in the only successful modified bolt.
The bolt was filled with pyrodust with the same burrowing method that Seth implemented the previous times.
However, inspired by a flute, Seth made five tiny straight holes. He then covered them with a fitting wood and sealed it with thin ropes.
This modified bolt was expected to deal a lot of damage when facing enemies. Seth had ten of these bolts and marked them with his blood to differentiate them from the normal bolts.
Seth went back to the tent, where he met the group. It was already nighttime, and the group was planning to get as much sleep as they could since they would leave before sunrise tomorrow.
