The implementation of the stash is nearly done! You will be able to access it from a few places, including Nora's house, Hunter's Hall and the Old Witch's house (after completing the Depths of Knowledge quest).
We are also sharing the item images of some of the new items coming in the next release. Including the Frog Skull Charm (Giving the wilder the ability to summon frogs) and a bottle with some unknown monster that Kara will be able to use...
Release of the test version will come in about a week (+a few days if anything comes up).
