For me when you start out with item progression.
Legendary item → Eternal item but depends on build → Crafting crystal item and using mythic
The problem with eternal is you can’t craft it and you can’t have all the affix that you need.
high lvl crystal and high lvl mythstones needs dedication.
List of affixes search for crystal.

After farming I aimed for a progression set and wanted to reach top 100 on the floors. It was on 750 floor that time on mythic 3.
My set then had
5 crystal crafted
7 set affix ( 1 was from legendary pet)
2 has mythic
1 eternal weapon
I sold a crystal item because it was a low ilvl (before I knew it was special) and am looking to avoid other mistakes. - [color=#FF0000]This can be crafted. You can raise quality by using emerald and lvl by using peridot.[/color]
I also am wondering if a mythstone recipe requires 4 stones, can the item have 5 sockets and the first four give it the talent? or is it like diablo 2 where there cannot be any extraneous sockets? - [color=#FF0000]As Far as I know if you get the right combination of the 4 slots on the specific gear it will craft to a mythic.[/color]
For tips on crystal crafting look at rubik’s guide
Are you using + 2 set mythstone or affix? it is really nice as set affix will be boosted. max is +4 set affix. If you have like rage set and have +4 on your set affix it will be rage(5)
