When the detect magic spell is cast, the cleric detects magical radiations in a path 1” wide, and up to 3” long, in the direction he or she is facing. The caster can turn 60° per round. Note that stone walls of 1’ or more thickness, solid metal of but 1/12’ thickness, or 3’ or more of solid wood will block the spell. The spell requires the use of the cleric’s holy (or unholy) symbol.
