The Blue Scribes can cast one spell from one of the eight Lores of Battle Magic in the Warhammer rulebook during each of his own Magic phases. You can choose which lore the spell is to be cast from, but must roll a D6 and consult the magic lore to see which spell is cast (the Blue Scribes can therefore never cast a signature spell). If there is no viable target or you choose not to cast the spell that has been rolled, the Blue Scribes do not cast a spell that turn. Spells cast by the Blue Scribes are treated as innate bound spells with a power level equal to their casting value.
