One of the things in my campaign was supposed to be a “holy” object and the more I thought about it, the urge to make it a bit silly grew. This will not be appropriate for all DW campaigns but my players found it lots of fun.
Duck of Judgment
“A solid Silver “duck”, about 50 cm high and with smudge and dirt all over. There appears to be something written below the dirt on its chest though.”
Roll+Wis when rubbing the chest. 12+ You are found worthy, so no effect. 10+ you’re a duck but can speak like normal. 7-9 You’re a duck, retain the mind of your own but can’t speak. Better hope someone in the party know animal talk! 6- Quack! Your’re a duck in all the ways possible.
The victim is a duck for 1d4/1d4 hours. So all from ~15 minutes to 4 hours.
(Edit: fixed the duration.)
