Forced March

Forced marches occur when a group of soldiers, travellers or adventurers are pushed to travel farther or faster than the distance that may normally be covered in the space of a day, depending on the terrain. This often occurs for reasons of urgency, where time is scarce and threats are imminent. A forced march usually exceeds the group's comfortable daily limits, causing exhaustion, reduced combat readiness, or physical strain. In game terms, it typically means extra distance at the cost of fatigue, requiring a constitution check and the need to rest afterward to restore penalties or avoid injuries.

The system outlines the mechanics for making exhaustion checks, which are used to determine how long a character can remain physically active before becoming unable to continue. Each character's threshold for exhaustion is based on their constitution score, which determines how much sustained activity they can endure before fatigue overtakes them. The Forced March Limits table indicates the point at which a humanoid character must begin making checks to avoid exhaustion.

Each successful constitution check allows the character to continue functioning for an additional hour of activity; with regards to combat, the check is made to learn if the character's able to remain combat effective for another five rounds. Further checks are made following the additional hour or combat rounds; should a check fail, the character is spent — their physical reserves exhausted. At that point, the character must rest, being unable to act otherwise, regardless of the activity.
