Saved all I'd acquired over the past year, which included taking a fair chunk of jobs to 90+ with some only being in subjob range at the start, and the only type that broke 1 stack was Snow, and I'd attribute that largely to doing a few trials in Ule where Ice weather is fairly common. Otherwise getting drops based on day is pitiful and relying on weather patterns for some is erratic at best. Fight, Light, and to a lesser extent Dark geodes are among the hardest to come by solely due to their respective weather issues. Sucks, but at the same time, geodes could be worse to get.
