Since the launch of the Delve expansion last year, many of you have been asking us to make Fossils stackable. We're excited to announce that we managed to resolve technical issues which prevented earlier implementation of this feature. We plan to introduce it by the end of this week in the 3.7.4 update alongside other improvements.

Once the 3.7.4 patch goes live, you'll be able to stack your Fossils, and will be able to socket them directly into Resonators from a stack. Common and valuable fossils stack to 20 and 10 respectively. The stack size in the wildcard slots of the Currency Stash Tab is 5000, like other currency items.

We plan to make similar changes to (empty) Resonators in the near future.
