Tracing Mirror

The Tracing Mirror is a Smurf-sized square handheld mirror used in "Beyond the Mirror's Reflection" in Season 10

Creation & Usage
It was created by Gargamel as a means of destroying the Smurfs because it was enchanted to turn whomever looked into it to stone. However, when the glass recieved a large crack from a disturbance, its power was weakened - instead of turning living beings to stone, it reveals their most recent past life. It is able to do so by tracing their soul to a previous point in time (which is why it's called the "tracing" mirror).

Gargamel left it for the Smurfs to find - which they do - and the first Smurf to see an unfamiliar reflection is Clumsy. It does not work for the Smurfettes in the village because, being magically created, their souls are singular and have not yet been directed to a second or third physical form. Being intended for the Smurfs, also, the aftermath of viewing the reflections differs for other species: when Ripple and Karma see theirs, they have dreams about memories of their past lives. The Smurfs, however, are unaffected after viewing their past life reflections.
