Stone Ground Stance is an augment spell with a range of 24". Until the start of the caster's next Magic phase, the target unit gains the Stubborn special rule (if they are already Stubborn, they instead become Unbreakable) and enemies charging them lose all charge bonuses. The Wizard can choose to extend the range of this spell to affect all friendly units within 12". If they do so, the casting value is increased to 16+.
