I farm Lord Zir because of Fractured Winterglass and all i got is this “not what i searching for” amulet.
I guess you need it in good.
I have a mediocre one (aspect) in the box, I usually sell them to the dealer without looking at them.
The next time I get one I can have a look at it and see if it’s any good.
Who knows, maybe if I keep an eye out for the Esadoras I’ll get a good FW 
but now that i have no more stygian stones i won’t be doing lor zir runs again until next week.
