Elemental Lariat, Where to spend KPs?

Just got this recipe to drop and looking to use it on my alt. Im unable to find ANY guides on where to spend your knowledge points to be able to max craft this.

I may not get any “Trade secrets”, But I figure its worth a shot in asking. Where have all you lariat crafters spent your points? What trees, Sub trees, Etc? This is ALL confusing to me to start throwing points in randomly

Setting > Necklaces I would presume.
Might want to search YT for some JC deep dive videos.
