Usekhp's Incantation

Until the end of this turn, the target enemy unit suffers a -1 modifier to its Strength and
Toughness characteristics (to a minimum of 1).
If this spell is cast, the effects of any other Hex
previously cast on the target unit immediately
expire.
As the Liche Priest intones the curse of desiccation
every syllable strips the moisture from their victims'
bodies, sapping their strength and vitality.
