Today's magic lesson is from the sorceress and Dzurlord Ibronka on a sorcerous field. "Ibronka stopped snoring, opened her eyes, and said, 'A sorcerous field refers to an area wherein the set effects of a sorcerous spell are continuous. Examples include teleport protections and alarm wards. The two advantages of a sorcerous field over a conventionally cast spell are that it may continue without monitoring for some length of time, and that additional energy may be put into the spell, increasing its effectiveness beyond what the sorcerer is normally capable of controlling. The usual way of determining if a sorcerous field is or has recently been present is the Norbrook Threepass Test.' After completing this discourse, Ibronka immediately closed her eyes and began snoring again." Sethra Lavode, paperback, Chapter the Ninetieth, page 248.
