You're not understanding the OP. He's not saying that the chances change based on the same number of variables. The chance of getting voidfang vestments EACH WEEK remains the same. That is separate from what the OP is saying - the probability of ACTUALLY getting voidfang vestments 4 weeks in a row is not the same. For example, you have a 50% chance to get heads. But if you rolled 100 times, and got heads EVERY time, the chances of getting heads 100 times in a row is lower (and it makes sense - how many times would you roll and get heads 100 times in a row. Would be crazy). But that has nothing to do with each instance of flipping the coin.
