Easy road
From Ardrana
The easy road spell ensures that the passage of the priest and his or her party along one path or road is quick and without mishap. The priest can enchant up to one mile of road or pathway per caster level, allowing the group’s rate of movement along the road to be increased without any noticeable spell effect. If the priest abandons the road or path to move across country to the destination, the spell ends immediately. In addition, for the spell’s duration, minor accidents, such as stones caught in a horse’s hoof or a broken axle on a wagon, do not occur.
Note: Easy road originally appeared in this form in Dragon Magazine 237 for the AD&D game from TSR. Its use here is for the purposes of providing context for the campaign only.
