In your soul, there is a gambling machine. At the start, the chances of you getting a jackpot is 1 in 100000, but with every roll the chances double. You cannot make a roll while a roll is already in progress. The time needed to complete a roll is based on its current success rate (if there is a 1 in 100000 chance of getting a jackpot, then the time needed to complete the roll is 1/100 of a second, if there is a 1 in 50000 chance of getting a jackpot, then the time needed to complete the roll is 1/50 of a second.)
When you get a jackpot, all your capabilities are greatly boosted, up to nearly a 100 times. The duration is based on the roll’s success rate (if there is a 1 in 100000 chance of getting a jackpot, then the duration is 10 minutes, if there is a 1 in 50000 chance of getting a jackpot, then the duration is 5 minutes.)
While you have a jackpot, you cannot roll.
