Incantation of Desiccation

Hex spell with a range of 24". The target has a -1
Strength and -1 Toughness (to a minimum of 1)
until the start of the caster's next Magic phase.
The Wizard can choose to reduce the target's
Strength and Toughness by D3 (to a minimum
of 1) until the start of his next Magic phase. If
he does so, the casting value is increased to 22+.
