Altitude Sickness
When an adventurer rapidly travels to great heights, even those with the most powerful constitutions face the risk of altitude sickness. After a half a day in the heights headaches, dizziness, and shortness of breath are the initial symptoms of what can become a fatal condition.
Born to the Heights. Creatures who were born or raised in high elevation (such as those from the Mountain Born culture) automatically succeed at this challenge.
Planned Ascent. An adventurer can plan a careful schedule with a successful Survival check, ensuring they and any companions do not climb too quickly and consume plenty of extra fluids. Those following the schedule automatically succeed, but their travel time is doubled and they consume an additional Supply each day.
- There is no guaranteed way to avoid altitude sickness if moving swiftly. Adventurers must hope they are hardy enough to acclimatize quickly or can return to lower ground in as short a time as possible. Each adventurer makes a Constitution saving throw .
