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 13 out of 24, and 6 out of 12 on whether anyone is inside the character. At the second offense it got stuck in a loop and never resolved the escape, so the letter did not burn.


You'll find the size band and figures for other models on the Tested models page.
