Name
blue cough disease — a contagious bacterial disease that affects focus in combat and while casting spells
Description
A hacking cough that is highly contagious. It is commonly caught in high altitudes and is so nasty that the victim has problems in battle. The victim will also have serious difficulty concentrating enough to cast spells. The cough will eventually run its course.
This is an exotic disease and as such, is beyond the capabilities of the average cure disease spell.
