Played through Dune Imperium with the Immortality expansion.
I found this expansion less fiddly than Rise of Ix, although I preferred how Rise of Ix made the green spaces and solari more useful. On the plus side: grafting was a powerful mechanic that’s right on theme.
Probably going to get this to the table again soon and try out both expansions at the same time.
I think it’s a Sansevieria zeylanica or something similar!
