How is the required level for an item calculated?

I haven't done a lot of testing on this, but I'm confused about how the required level of an item is calculated.

I've picked up many items with required level is = the base item's required level, and sometimes <40, that has the Fecund life prefix (90-99 life) which has required item level of 64.

However, when I crafted a Stone Axe (no required level) with blue Rustic Sash recipe, the required level suddenly jumped to level 8. But the Serrated prefix that was applied in this case is level 11, so that's not quite fitting either.

Is there some 'required level' on affixes, that are separate (and generally lower) than the item level required to roll it? I don't see that info anywhere on the Wiki.

Each base item has a minimum level.
Each added mod can be up to the iLevel of the item.
The required level would be the max of the base item and all the mods.

That is apparently not correct, based on the fact that the Serrated prefix requires iLvl 11 but I crafted a Serrated Stone Axe that had required level 8.

There is a paragraph in mechanics thread if I remember correctly, the level requirement is 80% of the highest mod level. I might be wrong better check that thread.

"The level of the magical modifiers. The level requirement for magical modifiers is equal to 80% of the level of the highest-level magical modifier on the item."

This is what I recall as well.

Cool, thank you!
