The Malign Sorcery boxed set is an expansion for Warhammer Age of Sigmar containing new rules and spells for magic, along with 17 imposing miniatures used to represent Endless Spells, powerful pieces of sorcery that can be unleashed by any wizard. These rules and miniatures can be used alongside the core rules to introduce wildly different and incredibly powerful spells brought about by the Arcanum Optimar – an age of rampant magic. When combined with the Realm of Battle rules found in the Warhammer Age of Sigmar Core Book, this set becomes a gaming toolbox you can use to fight narrative-driven battles in the Mortal Realms.
