Curse of the Leper can be cast on any unit (friend of foe) within 18". If cast on a friendly unit, Curse of the Leper is an augment spell that increases the target unit's Toughness by D3 (to a maximum of 10) until the start of the caster's next Magic phase. If Curse of the Leper is cast on an enemy unit, it is a hex spell that reduces the target unit's Toughness by D3 (to a minimum of 1 until the start of the caster's next Magic phase. The Wizard can choose to extend the range of this spell to 36". If he does so, the casting value is increased to 13+.
