All Wizards (friend or foe) within 12" of one or more models with a Blasphemous Tome gain +2 to their casting result when casting spells from the Lore of Necromancy. If any Wizard miscasts within 12" of one or more models with a Blasphemous Tome upgrade, they must roll twice on the Miscast table. The miscasting player's opponent chooses which result applies.
