When activated, you know if there is a powerful magical presence (be it an artifact, person, location, etc.) within 30 feet. You are only able to detect magical power of the opposite alignment to your own, i.e. good characters can detect evil magic and magic users and evil characters can detect good magic and magic users. Neutral characters cannot detect anything using this spell.
The spell can penetrate most barriers, but it is blocked by 1 foot of stone, 1 inch of common metal, a thin sheet of lead, or 3 feet of wood or dirt. When used, if you detect something, the sensation manifests as an odd, clammy feeling running up your spine. The stronger the magical power of the target being detected, the stronger this reaction. You are unable to tell what the target is or where it is, but your reaction grows stronger the closer you are to it. If there is no magical presence within the radius that you can detect, you sense nothing.
