You can sense the presence of law. The amount of information revealed depends on how long you study a particular area or subject.
1st Round: Presence or absence of law.
2nd Round: Number of law auras (creatures, objects or spells) in the area and the strength of the strongest aura present. If you are of chaotic alignment, the strongest law aura's strength is 'overwhelming' (see below), and the strength is at least twice your character level, you are stunned for 1 round and the spell ends. While you are stunned, you can't act, you lose any Dexterity bonus to AC, and attackers gain +2 bonuses to attack you.
3rd Round: The strength and location of each aura. If an aura is outside your line of sight, then you discern its direction, but not its exact location.
Aura Strength: An aura's lawful power and strength depend on the type of lawful creature or object that you are detecting and its HD, caster level, or (in the case of a cleric) class level.
Creature/Object = Law Power
Law creature = HD / 5
Law elemental = HD / 2
Law outsider = HD
Cleric of a law deity = Caster level

Law Power = Aura Strength
Lingering = Dim
1 or less = Faint
2 - 4 = Moderate
5 - 10 = Strong
11+ = Overwhelming
If an aura falls into more than one strength category, the spell indicates the stronger of the two.

Note: Each round, you can turn to detect things in a new area, but if you move more than 2 meters the spell ends. The spell can penetrate barriers, but 1 foot of stone, 1 inch of common metal, a thin sheet of lead, or 3 feet of wood or dirt blocks it.
