bro, you even math???there are 10 tools, each of the tool has 2-3 connection, each of those connections can be filled with 5 colors...there is a simple site wich i recomend http://www.calculatorsoup.com/ca ... cs/permutations.php
on this site you can simply calculate how many probabilities are(i got the number 27.625.770.144), now tell me how the hell am i supposed to get that many 5 nature runes, when i got 2 in the past 2 weeks... This post was last edited by 122***@facebook at 2017-1-25 08:21
It doesn't matter how many combination there be, because there is a large number of acceptable combination, and they are made from very few different possible pieces.
There are only 20 possible state for corner pieces, and 60 possible state for non-corner pieces. If you have one of every state of every piece, you will be able to make all the combination.
The question is then, how much does it cost to get every single state?
That is the coupon collector's problem.
The expected amount of roll required to get all 20 state of something is 72 (see coupon collector's problem) while for 60 is 281. Therefore, the expected number of stones you need to have the full set is 1974.
But the fact of the matter is, even for an optional set where, for example, you want 5 attack, 5 nin and 3 other connections, you do not need to collect them all.
Fact of the matter is, for this combo, for example, there are only a few "important" combination--ones where both attack and nin show up on the stone. There are a large number of state that you simply don't care for. As such, while the important state can end up as the last one, it's not expected to be so for all of them. Chances are, you can find an optimal set with under 300-500 stones, provided that you keep every single piece that can be a potential solution (since there are, I believe, 270 solutions)
