ESP

This spell permits the caster to detect the surface thoughts of one or more targets within range. The caster must designate a direction, and then concentrate for a turn in order to “hear” the thoughts. Each turn the caster may choose to “listen” in a different direction. The caster may stop listening, then resume again later, so long as the duration has not expired. The target creature is not normally aware of being spied upon in this way.

Rock more than 2 inches thick or a thin coating of lead or gold will block the spell. All undead creatures are immune to this effect, as are mindless creatures such as golems.
