Physical Ailments

Most physical ailments can affect both explorers and humanoid companions. Temporary ailments' icons appear fuscia and typically subside after 20-30 days (if the afflicted character doesn't succumb to their illness). The only ailments that animals can develop are injuries, infected wounds, and rabies.
