The character can sense the presence of law. The amount of information revealed depends on how long the character studies a particular area or subject.
1st round: Presence or absence of law.
2nd round: Number of lawful auras (creatures, objects or spells) in the area and the power of the most potent lawful aura present. If the character is of Chaotic alignment, and the strongest lawful aura's power is overwhelming (see below) and the Hit Dice or level of the aura's source is at least twice the character's level, the character is stunned for 1 round and the spell ends.
3rd round: the power and location of each aura. If an aura is outside the character's line of sight, then they discern its direction but not its exact location.

CREATURE OR OBJECT	AURA POWER
	Faint	Moderate	Strong	Overwhelming
Lawful creature¹ (HD)	10 or lower	11-25	26-50	51 or higher
Undead (HD)	2 or lower	3-8	9-20	21 or higher
Lawful outsider (HD)	1 or lower	2-4	5-10	11 or higher
Cleric of a lawful deity² (class levels)	1	2-4	5-10	11 or higher
Lawful magic item or spell (caster level)	2nd or lower	3rd-8th	9th-20th	21st or higher
1 = Except for undead and outsiders, which have their own entries on the table. 2 = Some characters who are not clerics may radiate an aura of equivalent power. The class description will indicate whether this applies.

Aura Power: a chaotic aura's power depends on the type of lawful creature or object that is being detected and its Hit Dice, class level; see the accompanying table. If an aura falls into more than one strength category, the spell indicates the stronger of the two. For example, as indicated on the table, a lawful creature with 51 Hit Dice has an overwhelming aura of law. A chaotic cleric who casts this spell and directs it at the location of such a creature for longer than 1 round loses the spell and is stunned for 1 round if the character level is 6th or lower.
Lingering Aura: A lawful aura lingers after its original source dissipates (in the case of a spell) or is destroyed (in the case of a creature or magic item). If Detect Law is cast and directed at such a location, the spell indicates an aura strength of dim (even weaker than a faint aura). How long the aura lingers at this dim level depends on its original power:

ORIGINAL STRENGTH	DURATION OF LINGERING AURA
Faint	1D6 rounds
Moderate	1D6 minutes
Strong	1D6x10 minutes
Overwhelming	1D6 days

Each round the character can turn to detect chaos in a new area. The spell can penetrate barriers, but a 1 foot of stone, 1 inch of common metal, a thin sheet of lead or 3 feet of wood or dirt, blocks it.
