Omen

The omen spell is used to forecast the general fortunes of some major undertaking and determine auspicious and inauspicious events. When the spell is cast, the caster calls upon a deity to grant him some sign regarding the proposed action. Although the physical aspect of casting takes very little time, the caster must remain in one place and observe the natural events around him for the entire casting time. At the end of this time, he sees some omen – a flight of birds, the appearance of an animal, the fall of a leaf, and so on, that indicates the general fortunes of the undertaking planned. This spell is commonly used before starting a journey, engaging in a major battle, or attempting some notable feat.

However, omens are infrequent events, and interpreting them is difficult. Due to the strain this spell places on the caster, it can only be used once per week.

Note: This spell originally appeared in this form in Oriental Adventures for Advanced Dungeons & Dragons (1st edition) from TSR. Its use here is for the purposes of providing context for the campaign only.
