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...
