Piglettron

My suggestion to identify how many people someone has killed with that character would be every person that they make dead adds 1 tally mark to their arm, sort of the way the silence works in Doctor Who just tally marks on their arms and if there is no more room put them on the legs then face. This why when you meet someone that you suspect might be a bandit tell them drop the shirt and then count the marks. Something like this would be really cool.
