Bless with Filth is an augment spell with a range of 12". The target gets the Poisoned Attacks special rule until the start of the caster's next Magic phase. If the unit already has Poisoned Attacks, the warriors will also cause an automatic wound on a To Hit roll of 6+. The caster can choose to increase the range of the spell to 24". If they do so, the casting value of the spell is increased to 12+.
