By casting a revelation spell, a wizard immediately understands, in unerring detail, the complete meaning of an omen or portent. This spell can be used only when the spellcaster sees the omen, and must be used while the portent is remains visible. The revelation spell cannot predict the future, except as indicated by the portent, nor identify what power sent the omen. The spell only reveals the exact meaning of the omen.
Should a spellcaster attempt to use revelation to understand an unusual event that is not an omen, the spell fails, although the caster does learn that there is no great importance to the supposed sign.
This spell can be blocked by magic or by powers of demigod status or greater, in which case only the general nature of the blocking forces might be revealed.
Notes: Uncommon for diviners; otherwise, very rare. (Updated from Legends & Lore.)
