The alchemist set has them drop at rate barely higher than card at 0.05... you can't be serious with it.
Even if GMs agree, it's not technically possible to drop more than 1 stem per kill. That's why heRO custom gears rely on different color of gift box to get around the problem. Nevermind, you can do it by making a new item group, and let stem be the only item inside the group.
As for stems, I still stand by the fact that the problem is caused directly by moscovia. Before the quest is implemented, stems just flow at 200z everywhere. I'm not saying quest should be removed, but rather we know that the quest is spawning some funny stuff as monsters. It'll be nice as a temporaily fix to just modify all spawned monster in the script to correspond with the lowest level cap monsters to give players benefit of the doubt. Getting the high end 1-1 classes back to moscovia will definitely help with the low supply problem.
If I remember correctly fabric was never an option.
In retrospect, skill reagents like those shouldn't be farmable with bee wings. Their power's supposed to represent the culmination of lots of work and effort, concentrated into one painful burst.
I think so too. Everyone who plays an AD Crea knows from the start, that this isnt a Sniper and that it is necessary to invest a lot of time or money to play it properly. And in my opinion the bee wings are making it pretty easy if you consider, what you are able to do with this Skill.
Put those wings on an autosteal rogue and go kill Les/Verits and you will farm Stems/Immortals pretty fast. Empty Bottles and Pspores are boring to farm but its not that slow either. Only fabrics are a pain.
