Rare item creation

[whathuh]

heh, I knew that one....

so you can have the max fire, poison and 300% ed spawn with say LL, ML and max light.

That can make an Uber Warpike  :ph34r:

i believe you can get:
Ethereal War Pike
Cruel +300% ED
Master's +150% ED +250 AR
Shocking +1-480 Lightning Damage
Of Quickness +40% IAS
Of Restoration 1 durability/20 seconds
Of Slaughter +20 Max Damage

yeah, I think mine will beat yours up any day.

Each affix has a rarity/weight associated with it. A rarity 2 affix would be twice as likely as a rarity 1 affix. Also, only affixes that can spawn on an item (based on the alvl and the item type) are considered.

Given this, it would seem the two methods are equivalent. In the first method, the weight of a group would just have to be the sum of the weights of all affixes in it.

However, in actuality, I believe the game first randomly decides whether something should be a prefix or suffix (50% chance of each) before deciding which specific affix it should be. There's a limit of 3 prefixes and 3 suffixes on one item, so if there are already 3 of one, the next affix must be the other.

Still I don't think they are the same. The whole reason behind my question is to selectively choose what types of affixes are going to go on my items. For example:
Let's say that the jewel affixes Tin, Nickel, Rusty, Pearl, Freedom, Avarice, and Realgar. Next, I cube a jewel selectively with the 6 skull method for a new rare to give it an output Ilvl of 13, putting the maximum affix level at 13. If this jewel can ONLY get 4 of these 7 affixes, which ones would it choose? I know already that Tin and Nickel are both AR affixes in the same group and Rusty and Realgar are both in the +ed group. Realgar and Pearl are too high Alvls to spawn on my jewel, so I'm left with 5 possible affixes. Let's say that there is no limit to the number of prefixes you can have on a jewel, just that it doesnt go over 4. Tin and Nickel are both in the same group yielding a possible choice of freedom, avarice, or rusty each at 1/4 chance. If Tin and Nickel are not counted as the same group, then the probability decreases to 1/5.

It doesn't matter much to me how much the affixes are weighted.
