You can see magical auras at all times by simply blinking to
activate this extra sensory ability. You may blink again to stop
seeing these auras. You can see these auras for as far as you
can percieve sight. If a magical aura has a particular school of
magic (such as enchanment) you may know that as well. You
also know the magical strength of the aura as defined by the
following:
Weak: The aura was created by spells of 1st to 5th level or
created by a spellcaster of basic or simple magical
prowess.
Intermediate: The aura was created by spells of 6th to
9th level or created by a spellcaster of some power.
Strong: The aura was created by a divine being, such as a
god (by means of the Creation divine feat or Alter Reality
divine feat), or an ancient or terrible power.
By spending 1 minute analyzing the aura you can
determine its magical properties and functions.
