You detect the surface thoughts of intelligent creatures around you. The amount of information revealed depends on how long you study a particular area or target.
1st Round: You detect the presence or absence of thoughts from conscious creatures that have Intelligence scores of at least 1 (or an Intelligence modifier of –5) or higher.
2nd Round: You detect the number of thinking minds and the Intelligence score (or modifier) of each. If the highest Intelligence score is 26 (or a modifier of +8) or higher and at least 10 points higher than your own Intelligence score (or 5 points higher than your own Intelligence modifier), you are stunned for 1 round and the spell ends. This spell doesn’t let you determine the location of the thinking minds if you can’t see the creatures whose thoughts you are detecting.
3rd Round: You can read the surface thoughts of any mind in the area. A target who succeeds at its Will save prevents you from reading its thoughts, and you must cast detect thoughts again to have another chance. Creatures of animal intelligence (an Intelligence score of 1 or 2 or an Intelligence modifier of –4 or lower) have simple, instinctual thoughts.
Each round, you can turn to detect thoughts in a new area. The spell can penetrate barriers, but 3 feet of dirt or wood, 1 foot of stone, 1 inch of common metal, a thin sheet of lead, or any force field blocks it.
