Where is the vials sts -.-

[Sabiee]

We need to craft nekro , i tried to farm vials every where ,like planner maps ,elite shuyal i heard i can loot there , still tried arena , i ddnt loot any at all, obviously the fossils ( the one and only arcane ingredient ) in crafting nekro recipe is way way easier to find than the vials , i hope there is a solution for this .
