Detect Undead

Standard Action | V, S, M/DF | 60 ft | Cone
Concentration, 1 Minute/level | None | No
You can detect the aura that surrounds undead creatures. The amount of information revealed depends on how long you study a particular area. The spell can penetrate barriers, but 1 foot of stone, 1 inch of common metal, a thin sheet of lead, or 3 feet of wood or dirt blocks it.
