Miasma of Pestilence is an augment spell with a range of 18". Until the start of the caster's next Magic phase, all enemy units in base contact with the target unit reduce their Weapon Skill and Initiative by 1 (to a minimum of 1). The Wizard can choose to cast a more powerful version of this spell that instead reduces the Weapon Skill and Initiative of all enemy units in base contact with the target unit by D3 (roll once and apply the result to all affected enemies). If they do so, the casting value is increased to 10+.
