A torture method created by the Illusionist.

The victim is tied down, and as punishment for their wrong doings, a Diamond shape is carved into their back and a line is carved over it. The Diamond shape in between the straight line is opened up and the victim is forced to go on with their day untreated.

The reason they're being punished is for committing sin against the Illusionist.

The Illusionist gave out this method, which is how he killed his father, but let his dad be tied down till he bled out.
