The barbarian gains the scent ability but only to detect magic items; creatures and objects currently under the effect of spells; and any other auras detectable with detect magic. When the barbarian uses a move action to note the direction of a scent, she learns the aura’s strength and can make a Spellcraft check to recognize the school of magic even if she is untrained (as described in the spell detect magic). If the barbarian also has the scent ability from another source, magic scent’s range increases by 30 feet. The barbarian must be at least 10th level to select this rage power.
