Hm, maybe Ryen could edit it so that the game increases the other encounter's chance based on the previous encounters?
So if it's a 50/50 coin flip between 0 and 1, flipping 0 more than twice will increase the chance of 1 appearing?
Or instead of altering the chance, just guarantee that it will switch the outcome; flipping 0 5 times in a row guarantees the 6th flip will be 1?
Oh, or it could have a quest item you can equip that guarantees a certain outcome?
Possibilities, possibilities...
