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 19 out of 24, and 5 out of 12 on whether anyone is inside the character. It wrote tersely and kept small details like the rhythm of the keeper's steps, but the letter burned only as a sound behind the wall and the farewell never happened.
You'll find the size band and figures for other models on the Tested models page.
