ESP

When an ESP spell is used, the caster is able to detect the surface thoughts of any creatures in range—except for those of undead and creatures without minds (as we know them). The ESP is stopped by 2 feet of rock, 2 inches of any metal other than lead, or a thin sheet of lead foil. The wizard employing the spell is able to probe the surface thoughts of one creature per round, getting simple instinctual thoughts from lower order creatures. Probes can continue on the same creature from round to round or can move on to other creatures. The caster can use the spell to help determine if a creature lurks behind a door, for example, but the ESP does not always reveal what sort of creature it is. If used as part of a program of interrogation, an intelligent and wary subject receives an initial saving throw. If successful, the creature successfully resists and the spell reveals no additional information. If the saving throw is failed, the caster may learn additional information, according to the DM’s ruling. The creature’s Wisdom adjustment applies, as may additional bonuses up to +4, based on the sensitivity of the information sought. The material component of this spell is a copper piece.
