Necropolis Crafting Corpse Level

Hello,
How does the corpse level impact the ilvl of the item?
If you have one ilvl 73 corpse and 60 ilvl 83 do you still can an 83 item?
Thanks

While I have no information if Necropolis works in this way, typically such systems take an average of the used components (in this case corpses). Again, I have done zero testing in this regard for corpse crafting.

I didn't end up using the 73 corpse, but I found out it shows the ilvl of the item after you select the base type.
Mine was 85 from a single 84 corpse plus a single +1 item level modifier corpse.

Not sure of the exact formula but surely it has been figured out. From limited crafting it seems to work off a weighted average to me. I think it's deterministic, because you can see the lvl before you roll the item. I think it is decided completely by corpse level, but not certain.

If you have a lot of lvl77 ish corpse and you add an 83, it might raise by one and vice versa, but it won't go drastically to the highest or lowest I don't think. If you put a very low corpse like lvl5 it will start to have a bigger detrimental effect. I think a low and high will go somewhere near the mid point, but it might be skewed a bit.

If you find the exact formula I'm interested to know. I don't think it would be hard to test, but the UI and uprooting graves makes the testing a little tedious. I don't see it being calculated on the craft of exile tool, I think you just put in the lvl value yourself. I'll check a few things in the grave yard but hopefully someone provides an already solved formula, because it would be useful to know.

Testing:

Corpse level 73 > ilvl 73
added 81 > 79 (Closer to top of range)
added 80 > 80
added 4 > 65 (now have 4 corpse 73+81+80+4=65)
remove 4 > 80
added 75 > 79 (73+81+80+75=79)
added 79 > 80
added 79 > 80
added 80 > 80
added 80 > 80
remove 75 > 81
remove 73 > 81
added 83 > 82
added 82 > 82
added 78 > 82
added 78 > 82
added 78 > 81
remove 78 > 82
added 78(+1 to ilvl) > 82
added 78 > 82
added 77(+1 to ilvl) > 83
added 75(+1 to ilvl) > 84
added 77 > 84
added 73 > 83
added 77 > 83
added 78 > 83
remove 78 > 83 (currently 17 corpse)
added 83 > 84
added 83 and connected to a disjointed 81 > 84 (20 corpses)
added 78 > 84
added 79 > 84
added 75 > 84
added 75 > 83
remove 83 > 83
added 75 > 83
added 78 > 83
added 79 > 83
added 79 > 83
added 75 > 83
added 77 > 83
added 77 > 83
added 73 > 83
added 58 > 83
added 29 > 81
remove 77 > 81
remove 77 > 81
remove 77 > 81
remove 75 > 81
remove 58 > 82
added 83 > 82
added 75 (+1 to ilvl) > 83 (30corpse, lowest 29, highest 83, sum 2300, average 76.7, final level 79 if 4 +1's are removed)
