(this should make it so if I were to win the tourney, then I've sold my soul, and if I hadn't won the tourney, tough luck. I think I'm winning the tourney tho, at least?)
I create the following promise ("Exorcism") in the library: { Cashing Condition: 4st has 0 blots, a promise with this text has not been cashed by the bearer prior, the bearer has expunged a blot from 4st in the past week, and 4st has won in the past week. Effect: Create a promise ("4st's Horcrux") in the possession of the bearer with the text: { 4st transfers any asset e owns to the bearer. } If less than 5 promises "4st's soul" exist, create a promise with this text in the library. } -- 4ˢᵗ Uncertified Bad Idea Generator
