Hazardous terrain, such as the caldera of an active volcano, might physically harm the PCs or their
vehicles. The group might have the option to travel directly through or to go around by spending more time. You can transition into a more detailed scene while the characters move through hazardous terrain and attempt to mitigate the damage with spells or skill checks. If they endure hazardous terrain, consider giving the PCs a minor or moderate XP reward at the end of their exploration, with slightly more XP if they took smart precautions to avoid damage.
