Detect Drow

When a detect drow spell is cast, the priest detects the presence of night elves and their kin in a path 10 feet wide and up to 30 yards long, in the direction he is facing. The exact number of drow can be determined. The caster has a 10% chance per level to determine the level and class of any drow so detected. The caster can turn, scanning a 60° arc per round. The spell is blocked by solid stone at least 1-foot thick, solid metal at least 1 inch thick, or solid wood at least 1 yard thick.

The material component of this spell is the priest's holy symbol.
