Based on the criteria provided, the story contains both tragic and comedic elements, though the tragic aspects are more pronounced due to the tension, conflict, and potential catastrophe that loom over the characters. The relief and preservation of heritage at the end mitigate the potential tragedy slightly, but the emotional journey is still heavily weighted toward a profound experience.

Thus, I rate the story as follows:

- **Tragedy Degree**: The plot involves high stakes with the potential for a disastrous outcome (artifacts with great power falling into the wrong hands). While the protagonists manage to avert this disaster, the intensity and danger of the situation contribute to a strong tragic element, though not the most extreme possible.
- **Comedy Degree**: There are moments of relief and a positive resolution, but the story doesn't focus significantly on comedic aspects. It is more of a dramatic adventure with heroic elements rather than a comedy.

Here's the evaluation in JSON format:
