When will Deadmines go out of stock?

I’m just a few hundred gold short and FiAV is coming up…

You have until mid-January, when the FiAV Miniset launches.

Sweet thanks

Do we have any idea what the FIAV mini will be? AB/WG?

No clue, but Wailing Caverns and Deadmines were both leaked shortly after the expansion release, so something similar might happed here.
