I know it's only open on the 6th and 7th of each month. But when it is indeed open, how long do I need to wait before getting a new gem from the Coda Caves?

Is it 3 hours? I forgot...

Thanks :)

3 or 4 hours is what I remember.

It varies, I believe.

Well, for me at least. Sometimes I only need to wait an hour, other times 3-4 hours. :(

For me it varies, once I got to go like every hour and a half and for May my wait time was like 5 hours or more.
