Headhunter got nerfed?

I don't remember since I played Harbringer, HH got nerfed to just 1 "monsters skills or?"

Im currently using "replica" cause it only costed me 1 div orb, it takes from blues only, but it only give me 1? will real one give me more than 1 and just from yellow right?

Magic monter's only have 1 mod to gain, where as rare have 3. This probably has a bit to do with why the non-replica is more expensive on trade.

"Explicit modifiers

Magic monsters have one affix; rare monsters have three affixes[citation needed], one of which may be an aura. "

The wiki says it takes all for the regular version. The repcica version does not specifically say this, but it has the same wording on the item, other than being magic, and 20% chance.

The inspired learning jewel also takes from rares, but only 1 and just 20 seconds.

It's possible there is further information to this and there may be other factors that I have missed. The only major change I see recently on the version history is a buff on the duration from 20s to 60s in 3.18. They have changed the mod pools quite a bit since harbinger league, so that may of had some indirect nerfs and buff. There's also been some power creep with other item inclusions, like mageblood, and enemy defense increases. I've used the Jewel but never used the belt, others may have a better knowledge if there where any nerfs that are not documented on the wiki.
