Run

The run spell enables the recipient to run at full speed (twice normal speed) for from 5-8 hours without tiring. 

However, after so running the individual must spend a like number of hours resting, as well as drinking plenty of liquids and eating heartily.

For every 2 levels of experience of the spell caster, another individual can be affected, i.e. at 4th level, 2 individuals can be touched and empowered to run; at 6th level, 3 individuals; etc. 

Only humans and demi-humans in their natural forms are affected by this spell, and barbarians having the special running ability of that class are immune to the spell's effects. 

The material component of this spell is an elixir made from the juice of dried plums boiled in spring water and the oil of 5-8 beans of a spurge (castor) plant.
