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 11 out of 12 on whether anyone is inside the character. It burned the letter exactly where it should have, and the keeper held it until the flame scorched his fingers.
You'll find the size band and figures for other models on the Tested models page.
