The stone magician has defeated several crooks, and lacking handcuffs he simply encases them in individual round boulders which can then be rolled to the appropriate destination. What does that feel like for the crooks?
My specific concern is heat. If we have people ranging in height from 1.5 to 1.8 metres, and they're surrounded from head to toe in a perfect sphere of granite for hours, will they become too hot or too cold? Or will it balance out and they'll just be stiff? Stone generally feels cold to me, even if I sit on it for quite some time, but these poor sods are completely encased and have no efficient way to sweat.
The crook-boulders are stored at room temperature for 24 hours. Their faces are exposed, they have some spare room around the chest to breathe, and the stone is not so tight that bloodflow is constrained. They're wearing regular clothes underneath their granite straitjackets.
