Spearhead: Bubonic Cell is a self-contained army boxed set for the Maggotkin of Nurgle faction in Warhammer Age of Sigmar. Released in January 2026, it functions as an alternative, thematic entry point for the quick-play Spearhead format. The army blends diseased mortal cultists and playful daemonic entities under the command of a rot-weaving sorcerer.
