Pretty self-explanationary. I'm sitting atop nearly a hundred thousand gems thanks to the Crom Cruach event and I'm wondering what exacly am I supposed to do with them? As far as I can see, I already have all the R kamihimes from the gem gatcha, but even if I they refresh it, it would hardly take more than a third to get those 5 or 6. Break limit expenses are basically covered as well..

I heard someone mention DMM introduces some gem sink and there are some speculations regarding it arriving here as well, but it was a single post and it didn't even mention anything beside the word "accessoaries."
