I haven’t seen people discuss this much in regards to Wil Wheaton’s dice curse but it isn’t originally his. He took it from someone else. For a few year’s prior to his Critical Roll appearance he was on another dnd podcast/live show called Acquisitions Inc.
In Acq Inc Jerry Hulkens was the one who always rolled low while Wil rolled all over the place, so you know, he rolled like a normal person. In their 2012 live show however things began to switch between them and with Wil leaving the group after that game he seemingly took Jerry’s curse with him.
Jokes about Jerry’s rolls seem to have left Acq Inc seemingly because Jerry lost his curse. And jokes about Wil rolling bad in CR took place years after making it seem to Wil like this has been happening “forever”.
Anyway, this has been my Ted talk on why dice curses are real and no, Critical Roll wasn’t the first dnd live show and definitely not the best one(opinion).
