Coat of Mist

A priest can use this spell to create a magical mist about himself. The spell can be used only at night, during a rainstorm, or at any other time natural mists might be present. The coal of mist improves the caster's Armor Class by 2, and gives a +2 saving throw bonus against fire- or sun-based attacks. These modifiers are cumulative with other bonuses the priest might have, but the caster can benefit from only one coat of mist at a time
