(Reversible to Obscure Alignment) A know alignment spell enables the cleric to exactly read the aura of a person - human, semi-human, or non-human. This will reveal the exact alignment of the person. Up to 10 persons can be examined with this spell. The reverse totally obscures alignment, even from this spell, of a single person for 1 turn, two persons for 5 rounds, etc. Certain magical devices will negate the ability to know alignment.
