Any Suggestion When Reinforcing Items?

Hi Guys! This is my first season and all the primals i have got were from Paragons or Kadala. Any suggestion or tips when reforging legendary items?
Some tips that i know is that “Magic Find” is indiferent for this cases and reinforcing items it’s all “random”, so it’s better to work on normal legendaries items and not ancient ones.

I’m trying to craft a Good Cesar Momento and a Won Khim Lau.

Thanks all!
