Hello friends!
I’m at the near tail end of HD, and need to snag a ray-drenched cinder. I’ve already used my first from finding the route to Nadir, but if anyone has any advice on how to make it easier to get them, or would be willing to spare one, I’d be incredibly grateful!
If you’re willing to wait until April, the ray-drenched cinder will be available for purchase from the Rat Market. You’ll still have to get lucky to have the right items to sell at that time as that’s random. See here:
