U shouldn't go under itemlvl 81... so u cannot use the same jewel over 'n over...
1) get jewels inside game
2) do not leave the game
3) go 'n craft jewels inside that same game because "somehow" their base itemlvl "99" will stay for 3-4 crafts before droppin... if u mule crap jewels itemlvl99 on a mule to craft l8r those jewels will drop itemlvl at 1st craft.
if u get any :
4%specific / 10+focus
4%specific / -10 req
4% specific / 2% ene or 1%attr
4%specific / 10fcr or 15fcr
even if it's not the one u're lookin for save it for trade for equivalent...
The jewels u want are -10% req / 4% / 10+ focus
And don't forget u can oil (of luck) all of them...
https://median-xl.com/char/jwls here u can see what u can get...
https://median-xl.com/char/poisonpark here's the parkin of sc ladder gear for a poison sorc and a cold sorc in Zann esu set...
some jewels are spread around... meh there's even a poison sorceress orb at 120%poison dmg...
the majority of -10%req/4%/focus are inside Sacred ceremonial Curandera
and 1 -10%req/4% is always inside those pieces with high req in str/dex...
But unless u put a crap jewel into a XIS rune u can always replace it...
