Warpstone Flux Rating: ⭐️⭐️⭐️⭐️4/5 stars. The rules are great!Background.More a mobile artillery platform than an actual combat unit, the Thanatar is a force to be reckoned with. Other than the plasma weapon originating on Ryza, little more is generally known about their backgrounds save rumours about where the Calix variant hailed from (within the sects of the mechanicum itself).Strengths.Wow.
