Know 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.

Certain magical devices will negate the ability to know alignment.

The reverse totally obscures alignment, even from this spell, of a single person for 1 turn, two persons for 5 rounds, etc.

This spell is essentially the same as the 2nd-level clerical spell of the same name, except as noted above, and with the following additional difference. 

Because of the shorter duration, only five creatures (maximum) can be examined by this spell, and it cannot be reversed.

Except as noted above, this spell is the same as the 2nd-level clerical spell of the same name. 

If a target creature is scried for only one round, only its alignment ethic (Law/Chaos) will be discerned.
