Warpstone Flux Rating: ⭐️⭐️⭐️3/5 stars. The rules are average for the points cost, although I can certainly see a case for a higher number of stars here depending on your tastes and builds. They're not as fundamental as in First Edition though which is why they're getting a slightly lower rating from me. Background. The background to this Space Wolves unit sees some tweaking for Second Edition.
