Okay, I really wanted to wait on this, but seeing as how a mislynch is likely while I am gone seeing how Ash hammered D1, here is my role.
I can inspect players weapons i.e. their dice. I can't find out how many dice they have, but I can find out what values their dice roll.
On N0, I inspected e/yuma and got the result 1,2,3,4,5,6,7,8,9,10,11,12
On N1, I inspected Mail-Mi because he did not roll that day and got the result 1,2,3,4,5,6,7,8,9,10,11,12
Originally, I was thinking scum had dice that could not go up to 12 which is why earlier I brought up that Hydrad had 7 twice and liopoli had 8 and then 6.
However, Faust had the suggestion that the dice stealer might roll a six-sided die. I don't know if faust was just theorizing or has an ability that rolls a six-sided die or is the dice-stealer himself, but that makes me think my role can find at least one scum. My guess is that their is likely one town with another die power and one scum. I might be wrong though. But, I am sure my role is good for something. I am probably the closet thing we have to a cop in this game.
