Detect Magic

You detect magical auras. The amount of
information revealed depends on how
long you study a particular area or subject.
1st Round: Presence or absence of magical
auras. 2nd Round: Number of different
magical auras and the power of the most
potent aura. 3rd Round: The strength and
location of each aura. If the items or
creatures bearing the auras are in line of
sight, you can make Knowledge (arcana)
skill checks to determine the school of
magic involved in each.
