A priest who casts this spell is immediately able to determine if the subject
creature deliberately and knowingly speaks a lie. It does not reveal the truth,
uncover unintentional inaccuracies, or necessarily reveal evasions. The
subject receives a saving throw vs. spell, which is adjusted only by the Wisdom of
the caster--for example, if the caster has a Wisdom of 18, the subject's saving throw
roll is reduced by 4 (see Table 5: Wisdom).
The material component for the detect lie spell is one gp worth of gold dust.
The spell's reverse, undetectable lie, prevents the magical detection of lies spoken by the creature for 24 hours.
The reverse requires brass dust as its material component.
