This page is in need of content.

Add links to the spading sheets, add explanations for selection of results
There are some vague or non-exact figures and information on this page. Some spading is required.

Remaining seeds

To reduce variance in ascensions some content uses formulas of different kinds to select results. Some use simple formulas while others produce random values from a random number generator seeded with a deterministic value. This results in the same values being generated whenever the input variables are the same. Most commonly in-game this will be experienced as a given class in a path receiving the same items every ascension, while a different class or path receives a different set of items.

For brevity this article only covers formulas where the results can differ between players or ascensions.
