For the duration, you sense the presence of magic within 30 feet of
you. If you sense magic in this way, you can use your action to see a
faint aura around any visible creature or object in the area that bears
magic, and you learn its school of magic, if any.
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.
