Detect Magic (Reworked)

A pulse of energy radiates out from you. If magic is present within 30 feet of you, a faint aura becomes visible around the creature or object bearing it, or within the space of the affected area as the magic sparks a reaction. You learn its school of magic, if any.

Subjects marked in this way retain their glow for one minute before the aura becomes too dim to perceive any longer.

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.
