When this spell is cast, the priest sees any psionic use in the area of effect as a rosy glow outlining the psionic creature. The more PSPs the creature uses, the brighter is the glow (faint 1 to 5 points, moderate 6 to 10 points, strong 11+ points) The caster can turn slowly, scanning a 60º arc per round. The caster also has a 10% chance per level to determine the psionic discipline, attack mode, or defense mode being used. Any material barrier at least one-inch thick blocks this spell.
The spell requires the priest's holy symbol, and a dew drop collected from a spider's web.
