Temporal Eraser

Description

This seemingly mundane white eraserhead can be used to scrubbed away evidence of your passage in an area of effect. You can break down the eraser into a fine dust and blow it over the area of effect to instantly destroy all mundane evidence of its occupants having passed through, as if the space were undisturbed for a decade; furthermore, the eraser's use leaves no magical residue. Alternatively, if you manually scrub the area of effect with the eraser, the item persists and can be used again, but it takes time to do so: at 1 strength, the eraser is large enough to affect a surface area equal to a personal space and takes 5 minutes to erase manually; at 2, a melee space and 15 minutes; and at 3, an encounter space and 30 minutes.
