Continual faerie fire

From Ardrana

The continual faerie fire spell is most often used to illuminate temples or temporary places of worship. It allows a priest to cover an area with a pale, glowing light. Unlike less powerful faerie fire, this radiance can be of any color desired by the caster. The spell's area of effect can be of any size, but it must be continuous. A row of patches of light the size of coins would require a row of spells, whereas a ribbon or circle of light in the same area could be created with a single spell.

When in contact with the lit area, all beings and objects are outlined with a slightly more intense light than their surroundings. Invisible creatures are also surrounded with a nimbus and revealed if in contact with continual faerie fire, but non-corporeal, ethereal, or gaseous creatures are unaffected. Undead creatures, however disguised, display an aura of blackness when in contact with continual faerie fire.

All creatures and objects possessing or under the current influence of cast magic that is not part of their essential nature radiate an additional flickering white aura. Spellcasting or activating a magical item while in contact with the radiance of continual faerie fire is accompanied by tiny, winking white motes of light. The white aura concentrates around magical items and surrounds beings under a dweomer. The whole of any illusion also glows with this flickering white aura. Aura effects are cumulative: an undead creature imbued with spell ability or disguised by an illusion would have a black aura haloed with a flickering white one. Moving objects and creatures retain a glowing outline for one round after they leave the area lit by the spell.

Continual faerie fire operates independently of magical light and darkness, functioning as if neither existed. Within areas of bright light, the winking white lights of magical outlines are hard to see, and the colored outlines around beings and objects appear as a faint fuzziness around the perceived edges of their outlined forms.

Note: This spell originally appeared in this form in the Prayers from the Faithful supplement for Advanced Dungeons & Dragons from TSR. Its use here is for the purposes of providing context for the campaign only.
