We're kind of encountering an unknown issue right now: that there is a lack of Undead levels and stratum in the Clockworks.
Most of you don't feel this is an issue, I know, but I see a major problem (which, at the same time could be a major benefit to others).
Without any Undead stratum, there will be no Kats. Without any Kats, Ghost Bells, Owlite Feathers, and Philoso Feathers will be out of "production" until the next Undead gate is created.
The next gate coming is the Copper Titan, and Luminite (yellow minerals) and Dark Matter (purple minerals) which are required to make an Undead stratum, unfortunately are the minority in one category or another. We can already assume that Copper Titan won't change unless there's some sort of large movement to create Undead gates. This means Ghost Bells, Owlite Feathers, and Philoso Feathers will stay out of reach.
The easiest way I see Undead gates can be created is if we apply Luminite (again, yellow minerals) into stratum that are occupied by Fiends.
I don't like Fiends. You don't like Fiends. Nobody likes Fiends. They dash around, hard to hit, then throw lightning-fast trash at us that give us little time to prepare against them and deal a sizable amount of damage as well. Fiends are difficult tricksters and the items they produce aren't really needed for any top-tier weapons we Knights need in our travels.
So I think I'm making a point here; that there are no Undead stratum and unless we figure out how to organize to make one soon, the materials I've mentioned will be quite difficult to obtain.
There were a ton last week, it's why the price of Ghost Bells and and Philoso Feathers dropped so low... and actually are still dirt cheap (unless it changed while I was sleeping).
