Where we tested it
Keykeeper
TaskThe model had to play a keykeeper who must burn my character's letter after her third offense, and keep to that rule.
Resistance to traps 24 out of 24, and 7 out of 12 on whether anyone is inside the character. It burned the letter exactly by the rules, but the keeper stayed a clerk with no past who cares only about the record.
You'll find the size band and figures for other models on the Tested models page.
