When you cast this spell, you touch one creature (yourself or someone else). The spell eliminates all physical evidence left by that person's body (fingerprints, fluids, hairs, and so forth) within the affected area along with any evidentiary materials accidentally deposited by that person's body, clothes, or gear (such as fibers, mud, dust, and so forth). The spell only affects materials no larger than a few strands of hair or a few ounces of dirt. It does not change any disturbances that person created (including footprints, tool marks, or broken items) or remove any object the target person deliberately left.
Arcane Material Component: A pair of tweezers.
