You can sense the presence of fire and heat. The amount of information revealed depends on how long you study a particular area or subject.

1st Round: Presence or absence of heat.

2nd Round: Number of sources of heat (creatures, objects, or spells) in the area and the power of the most potent heat aura present.

If you are of the cold-subtype, and the strongest heat aura’s power is overwhelming (see below), and the HD or level of the aura’s source is at least twice your character level, you are stunned for 1 round and the spell ends.

3rd Round: The power and location of each aura. If an aura is outside your line of sight, then you discern its direction but not its exact location.

The spell otherwise functions like Detect Evil, except that it detects heat energy from normal fire, fire spells, fire magic items, clerics of fire deities/with the fire domain, and all living beings other than those with the cold subtype.

Living beings without the fire subtype are detected with a heat aura strength of faint only, regardless of level or Hit Dice.

A fires power depends on the type of fire creature, spell, or object that you’re detecting and its HD, caster level, or (in the case of a cleric) class level; see the table below. If an aura falls into more than one strength category, the spell indicates the stronger of the two.

Aura strength
Target None Faint Moderate Strong Overwhelming
Subtyped creature (HD) - 2 or lower 3-8 9-20 +21
Fire Outsider (HD) - 1 2-4 5-10 +11
Cleric, Paladin, or class specifically aligned with a fire deity (class levels) - 1 2-4 5-10 +11
Fire Magic item or Spell (caster leve) 5 or lower 6-10 11-15 16-20 +21

Living beings without the fire subtype are detected with a heat aura strength of faint only, regardless of level or Hit Dice.

Lingering Aura: A fire 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 firel 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 1d6×10 minutes
Overwhelming 1d6 days

Animals, traps, poisons, and other potential perils that don’t produce heat are not detected by this spell. Each round, you can turn to detect fire in a new area. 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.
