A useful and powerful defensive spell against evil and undead. Many a dungeon adventurer has attributed their survival to its use. It is commonly available to priests of any non-evil priesthood.

When casting, the spell can be centered at any point in the air within the range, or upon a single object. If cast upon an object, the light moves with that object. It cannot be cast on a creature or person.

Once cast, the spell generates a soft white light, which protects a spherical area up to 20' in radius. The light lasts for 1 turn, plus 2 rounds per level of the caster, but will end sooner as desired by the caster or if the distance between the caster and the light soruce exceeds 60'.

For characters and creatures other than evil and undead, the brightness of the light can be as dim as candlelight or as bright as torchlight, as desired by the caster. It does not affect infravision when set to candlelight. To evil and undead, however, the light always appears piercingly bright, and causes them great pain to look at the light or remain within the protected area.

Any evil and undead creatures within the protected area suffer a -1 penalty to their hitrolls and saving throws for every 4 levels of the caster, and must make a save vs. spell each round or be driven from the protected area. Creatures driven away in this manner cannot re-enter the protected area. Each round that they remain in the protected area, they suffer 1 point of damage for every 4 levels of the caster.

Evil and undead creatures outside of the protected area must make a save vs. spell (with above listed penalty) in order to attack characters within the protected area, or to cast spells in the direction of the protected area. Failing their save means they are driven back, or lose their concentration.

The material components for this spell are the priest's holy symbol and a purified white candle. The candle is expended in the casting.
