This spell is a multiuse incantation that can be cast in one of three forms. Unfortunately, the casting of this spell borrows the sunshine for the day it is cast (or the next day if cast at night) to render these effects. This spell is very unpopular among farmers and ranchers, who see it as a miscarriage of divine intervention.
- Light: Advanced sunshine can be used to borrow sunlight from later in the day (or the next day if at night) to create light now. This is useful in caverns or at night. This form of the spell is treated as a light spell lasting one turn per level of the caster, but it shortens the day's sunshine by one minute per level.
- Fireball: A piece of the sun's energy can be converted into a fireball as though cast by a mage of the casting priest's level. This lowers the temperature within a 90-mile radius by 1 degree Fahrenheit for a tenday each time it is cast. This aspect of the spell cannot be cast at night or during cloudy days.
- Illumination: This version of advanced sunshine can be used to borrow sunlight from later in the day (or the next day if at night) to cast continual light at double the range and effect for the caster's level. This shortens the day's sunshine by one hour.
Notes: Granted by the sun god Amaunator of the Forgotten Realms setting.
