someone help me with this number crunching.
I go to calculate the odds of grizwold generating a king's bastard sword of haste at clvl 28 and here's what I come up with .167(prefix and suffix)x.0555(qlvl 10 base item)x1/3(chance of qlvl 10 item of being a bastard sword)x.07(qlvl 28)x.5(chance of qlvl28 of being kings)x.07(qlvl 27, haste)x2(number of possible slots this can be offered in) with this I get 1.513x10^4 or a 1:6609 chance of him generating it, is this accurate or did I make a mistake somewhere?

That's what I got, but I encourage you NOT to trust my answer. I am not any good with math at ALL, I'm the one who's a jr. in highschool and has problems deviding without a calculator.
I knew it! You actually bothered to read this signiture!

I'm actually looking for someone to check my numbers.. not calculations to see if they're correct, maybe Jarulf or someone?

>.167(prefix and suffix)
Seems OK. >x.0555(qlvl 10 base item)x1/3(chance of qlvl 10 item of >being a bastard sword) It is really not a 2 step procedure and I don't know how you got the numbers. There are 33 possible base items, so it should be a 1/33=0.0303 chance. That is slightly different from what you got. Perhaps I missed something. What is the first number you have? >x.07(qlvl 28)x.5(chance of qlvl28 of being kings) ??? You mean picking the prefix? Again, sum up all the possible prefixes (x), then there is basically a 1 in x chance it being a king's. ON a quick count, I got 22 possible prefixes, so 1/22=0.0455. >x.07(qlvl 27, haste) Again, I got 15 possible suffixes so 1/15=0.0667. This might be what you had rounded though :) >x2(number of possible slots this can be offered in) Ehh, Well, there might be some slight changes for the clvl+1 and clvl+2 slots. For the clvl1 slots he can't offer it at all. SO 4 possible slots with two of them slightly higher chance than the above. I don't know if I made some errors. So long since I looked at all this.

so the game doesn't roll the qlvl before determining the base item, prefix and suffix? cause I thought it'd pick a qlvl of the item then check the possibilities, like roll a qlvl of 10 then checking the qlvl 10 items, then see that it contains bastard sword, battle axe and maul then pick 1 of those 3 items..

It is a fixed value for each one. When you create an item (see my guide for more detailed info), the item is given an item creation level (ilvl). Now, when picking the base item, it will basically make alist of all base items that are (for Grisowld) in the range of ilvl/4 to ilvl, that is who's quality level is in that range. Then pick one at random. When picking affixes, it will make another list (seperate for prefix and suffix) of all that has a quality level in the range of ilvl/2 to ilvl and that can appear on the picked base item type. It then pick one of those at random. My guide actually has a very complete and exact step by step procedure for how the item is generated, try following it again and see that it works like I said here. There are three types of people in the world. Those who can count and those who can't.

Well here it is with updated numbers at clvl 28
.167{prefix and suffix} (1/31){bastard sword} (1/26){king's} (1/24){haste} 4 {slots it can be offered in} multiplying it all together I get 3.453*10^5 or a 1:28958 chance of Grizwold generating it.. doesn't look so easy now.. EDIT: hehe did wirt's stats and I got 4.387x10^6 or a 1:227928 chance Double EDIT: just realized that the base items don't include jewelery.. do I just add 2 to the existing 31 or is it done differently?

Assuming 31 is the correct number of base items, you would need to subtract 5, because there are three seperate base rings and two base amulets. IIRC, bows have a double chance of being selected, as do some prefix's or suffix's. You would have to take that into account as well.

That is from normal monsters only or something like that. Not in town. > as do some prefix's or suffix's. Yes, true. There are some combinations that are not allowed though, so that cut it down some in those cases. My Guide has tables for all of that of course :D There are three types of people in the world.

yea using the tables I got those numbers cept it should be 1/36 for bastard sword instead if there's 3 rings and 2 amulets slots. Other than that it should all be good.. should make a table of statistics of the most sought out items and make a sticky out of it

Why do all those calculations when you can just take whatever gris sells you if you like it, if you don't like what he sells you, then there's always next time. I got a king's sword of haste, only broad sword though, I love it. I also bought a king's/stars from him and a king's battle axe of haste.

Hail Saltman,
If you were to lurk to become more familiar with these fora, you would find that you have come across a community of people who really do care about these figures: we want to know the odds of things, formulae, and other mathematical aspects of the game. Then there's Jarulf, who posts lots of numbers and things...I think it's mathematics, but I cannot understand all of it :lol: May the wind pick up your heels and your sword strike true.

I'm a newbie at Diablo.Maybe I do not understand somethingbut what's the point in calculating what the chance is?! You either get it or not...

Hi,
However, the way I play, I seldom have characters with great gear. The only "runs" I've ever made where for the Helm of Sprits for my "big" warrior. And I hardly ever played him after getting it. ;) Many people play for the gear. Multiple Laz runs or hours of starting new games to shop at Griz (or Wirt). For those people, the odds of getting something pretty much converts to the number of hours they have to spend searching. So they like to know the odds so that they can figure if the item is worth the time. I guess playing by itself isn't sufficient reason to spend the time. Go figure.
