I recently reactivated two of my accounts, both over 15 years old and have a few questions about item generation that I was unable to find on my own...
I played under the item change that came with AoS, so I'm familiar with older mechanics of random magic items having a set number of magic properties and each property having a particular intensity... Each monster had caps as to how many properties were likely to show up on an item it dropped and what fraction of maximum intensity those properties could have... IIRC, luck skewed the results higher but within the caps for the monster you were looting.
T5 maps and SoSs had the chance for good loot (I believe T5 could go up to 100% intensity) and items could then be enhanced with the colored ore or leather of your choosing (with an absurdly high break chance for intensely magic items)
So I'm reading about changes I assume came about in pub 73? with a shame loot change? There is now a notion of a properties budget that items have when they're being generated, negative properties that are more likely to appear on higher end items that in turn supply the items budget with a little more points... but everything has been phrased in qualitative language in those explanations.
Is there any place to look for quantitative information about the mechanics of item generation ? For instance I don't know how this property budget translates into more properties on an item, I don't know if there is a maximum number of properties a legendary artifact can have (or any classification for that matter) I don't know if there is a system constraining the overall intensity (like I read about imbue weighting) I don't know what monsters supply what item property budget (and bonus) and I don't know how found items compare to treasure maps, SoS's or runic made items...
There used to be resources (some time after AoS hit) that provided number of properties and intensity maximums associated with each monster that governed the generation of items they dropped, that was very useful in targeting monsters for specific items (and not doing more work than was necessary, instead going for volume to get said item properties faster)
Judging from the sheer number of properties I've seen on some screenshots of legendary artifacts it wouldn't surprise me if the number of properties is somehow "soft capped" and determined by a series of rolls with diminishing returns.
I've got a good enough memory of farming for hours and hours on end with my tamer, sorting through loot, to realize there is a good deal of distance between knowing the mechanics of loot generation and exploiting them, but I'm still extremely interested. Any information would be useful and much appreciated.
