by what equation
Number of prefixes and suffixes are first set :
3 prefixes : 1/64
3 suffixes : 1/64
2 prefixes + 1 suffix : 3/64
1 prefix + 2 suffixes : 3/64
3 prefixes + 1 suffix : 5/64
1 prefix + 3 suffixes : 5/64
2 prefixes + 2 suffixes : 6/64
3 prefixes + 2 suffixes : 12/64
2 prefixes + 3 suffixes : 12/64
3 prefixes + 3 suffixes : 16/64
Then, until that number is reached, an affix is randomly selected among a pool of available affixes (depending on item type and item level).
Once an affix is selected, no other affix of the same group can be selected after, reducing the affix pool.
This selection is based on different weights for each affix.
Google :
affixes for lod-items
first link, "switch to classic" (if you need), select an item and click "show affixes".
Weigths (frequencies) are displayed.
You can also select a quality (magic/rare/craft) and click "calculate affix-chances".
