Reception
{{Expand section|date=June 2025}}
Shannon Appelcline commented that the module "does a great job of providing good reasons to adventure across Wildspace from one sphere to another", however, the Spelljammer campaign setting "never brought together its many spheres into a coherent setting" and the spheres introduced in this module "would never be heard from again". Appelcline highlighted that "Crystal Spheres lies on the line between the adventuring tropes of the '80s and '90s" and "also includes a beautiful chart comparing the sizes of the many spelljamming vessels revealed to date – including the Hummingbird from this very adventure".
