What about x3 -int on EA/Assasin bracers?
Which seems to be the most annoying thing in-game to get. Crunching the numbers would make me feel a bit better about myself.
lots of pinoys would disagree with you.
1/(0.0816^3)= 1840,47
1 in 1840 tries. multiply that by 310,5/90 = 3,45, and it makes 5521 damascenes.
however, if we were to count the actual chance, after 1840 tries your chance to get them is (1-1/1840)^1840 = 63.21%, and after 1275 tries your chance to obtain them reaches 50% (log(1-1/1840) 0.5).
in future,
http://epicpw.com/index.php?topic=7835.msg100920#msg100920 is where it's all explained in case you want to count the chances yourself.
EDIT: PWDatabase chances for HA and LA classes are not correct because there is hidden chance for channeling. How to calculate them, then? Observe the chances page, you will see there are a lot of attributes with same chances of obtaining and a few with lower chances. Take
Demonhunter breeches for example. Most of the attributes have 8.43% chance listed, while critical hit rate has 5.56% chance and elemental resistance has 1.69% chance.
Now add up chances of those lower chance attributes. 5.56% + 1.69 % = 7.25%. Subtract this number from 100 (or 1). 100 - 7.25% = 92.75%. This is the shared chance of obtaining any of the regular-chance attributes. PWdatabase shows there is 11 of them, so when you divide 92.75% by 11, chance for a single attribute will be 8.43%. However, we know that there is another regular-chance attribute, that is -channeling. So we have to divide by 12.
92.75% / 12 = 7.72%. That is actual and correct chance for obtaining any regular attribute on Demonhunter breeches, which includes channeling.
