Truth-Testing is a Divination spell that a Mage or Sorcerer may cast this spell and then concentrate on a target within range to see if the person is telling the truth by discerning disturbances in their aura caused by lying. You will not be able to tell what the truth really is, uncover unintentional inaccuracies, or necessarily reveal evasions. The caster must focus with a small mirror, must say the spell correctly, and complete the appropriate hand gestures in order to cast the spell.
