The Demon Sage

The best time to perform an exorcism ritual is on a night when the moon is just rising, or at dusk, just after the sun has set. The moment the last ray of sunlight disappears, evil creatures are set free, and they cheer with joy.

Their mood affects the success rate of the exorcism ritual.

Because of the magic involved, the ritual should not be performed at home. It is best to choose a sparsely populated forest or clearing, an abandoned factory, or somewhere similar.
