When you cast this spell, all footprints and fingerprints within a 30-foot radius around the point of casting become highlighted and glow faintly for the duration. When you cast the spell, choose any point in time up to 10 days ago. Only footprints and fingerprints left between that time and the present will be highlighted. Each creature that leaves footprints and fingerprints is assigned a unique color, but are not otherwise identified. Any creature that moves or touches objects within the Emanation will also leave colorful footprints and fingerprints, which might reveal invisible creatures in the area.
