Merciful Shadows (Reversible)

This spell creates a magical shade to protect an individual from the scorching sun. Once cast, the individual gains the benefits of being in the shade (half water consumption requirements), even when traveling or fighting in the full light of the sun. The individual so protected appears normal, except that he doesn't sweat as much as expected and his coloration is a bit gray.

The reverse of this spell, blistering rays, intensifies the light and heat of the sun on the subject. The individual must have twice the water per day for duration of the spell or suffer the effects of dehydration. Also, in each round of combat in the open sun, the individual must make a constitution check to keep from passing out. The saving throw, applicable only to the reverse of the spell, negates its effects. This spell (and its reverse) has no effect on an individual who is in the shade.

The material components of this spell are a piece of a palm leaf (or black fabric for the reverse).
