For the purposes of bypassing DnDBeyond's filter, this spell is not the same as Detect Magic. Look, I added one whole sentence. It's a different spell! Totally different.

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 faint lines between that creature or object and any other visible creature or object to which its magic is connected. You learn the school of magic, if any, of each aura and connected line.

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.
