Detect Balance

This spell allows the druid to determine if non-Neutral forces and alignments are at work in the area of effect (upon or in the object or creature being scanned). 

An alignment that is partly Neutral (such as that of a Neutral Good cleric) will radiate a mild aura, while an alignment that has no Neutral component (such as that of a Chaotic Good fighter) will give off a strong aura. 

The spell does not determine exact alignment, but only tells the druid if the object or creature being examined is something other than true Neutral; a paladin and a Chaotic Evil thief, for instance, will radiate the same aura at the same strength.
