The reason you wouldn't see 2 geodes in an abyssea ally is because the drop rate on day is abysmal. I attempted to farm flame geodes last night during firesday and got 0. There was a tiny window where wind weather showed up during firesday and the first mob I killed during it dropped a breeze geode... was kinda sad but whatever, breeze geodes still go for a bit on siren. If SE is unwilling to make fire weather more common, it would be nice if the drop rate during days wasn't so bad that you completely waste about an hour trying.
