The short trip made Rosalind realize a lot of things. First, surviving in an unknown environment was very hard, second, talking was definitely easier than doing and third, being confident was not enough. One needed skills to back it up. Finally, one could not just build a skill overnight.
Skills needed practice and perseverance, patience and motivation. The Duke repeatedly asked her to use her Blessing to enhance her vision and since she was not used to it, her head immediately started hurting. She realized that while she might be powerful compared to a normal human, she was still useless in front of a warrior.
The light Blessing was meant to support the warriors. They really had no real life-saving skills. If she wanted to survive out there then she needed to learn how to protect herself.
Rosalind eyed her red, swollen hands. Pulling the string of the bow was hard, perhaps it was even harder than just pointing the arrow to a target.
