Usirian's Incantation of Vengeance is a hex spell with a range of 18". The target unit suffers -D3 to its Movement (to a minimum of 1) and treats all terrain (even open ground) as Dangerous Terrain, testing every time it moves (including when charging, fleeing, pursuing, moving compulsorily, etc.) until the start of the caster's next Magic phase. The Wizard can instead choose to extend the range of this spell to 36". If he does so, the casting value is increased to 13+.
