Omen (Faerûnian spell)

Omen was a common divination spell that was available to numerous Faerûnian priests of various faiths.

Effects
This spell was used by a divine spellcaster to beseech their deity for advice regarding a binary choice that had been presented to them. When the spell was cast, there was significant chance the priest would receive a symbolic, but definitive response either in the affirmative or negative. It was also possible they received no response whatsoever.

It should be noted that any divine "signs", or misleading coincidental occurrences, were up for interpretation by the priest.

Components
In addition to verbal and somatic components, omen required a single gemstone worth at least 100 gp, that was consumed during casting.
