This spell allows the caster to sense the basic needs, drives, and/or emotions of any unshielded mind (hunger, thirst, fear, fatigue, pain, uncertainty, rage, hatred, curiosity, hostility, friendliness, love, and so on). The spell gives no result for creatures protected against detection, psionic creatures, or emotionless creatures (such as slimes, oozes, jellies, golems, skeletons, zombies, etc.).
The reverse of the spell, mask emotion, conceals the emotions of the protected creature for one turn.
The material component is the priest's holy symbol.
Notes: Very rare spell. (Updated from Polyhedron Newszine.)
