My group and I started Strange Aeons about two months ago, and I like to use the adventure path dice sets for the AP. It seems like they skipped over Strange Aeons though. Since we've started playing the Ruins of Azlant and Ironfang Invasion sets have come out. Is there any reason they would skip and AP dice set? I just thought it was weird. I'm hoping the dice set comes out before we finish the AP so I can at least use them for a little while.
Q-Workshop is on their own schedule.
The dice don't always come out at the same time as the AP.
Also, instead of coming out ABCDE, they may come out ABDEC.
This is due either to design or production problems that wasn't anticipated.
So don't worry if a dice set isn't out yet, it will come out eventually.
Back when Q put out the WotR set, I believe, I contacted Paizo about when they might get it in (cause there was a bunch of other sets not on the site too), so it's probably just a minor slip up somewhere.
