Suspend Magery (VH)

Regular; Resisted by Will+Magery 
Temporarily nullifies the subject’s Magery. The caster must touch the subject throughout the casting. The subject retains his knowledge of spells, but cannot cast them – unless he is in a high-mana area, of course, in which case he simply loses the bonus. Even in a high-mana area, the subject cannot cast spells that require Magery of any level. Suspend Magery can only be removed by Remove Curse. 
A critical failure with this spell costs the caster a level of Magery for 2d days. At the end of that time, the caster should roll vs. IQ+Magery; any roll except a critical failure means that the lost Magery is regained – a critical failure means the loss is permanent!

Duration: 1 hour. 
Cost: 12 to cast. Same cost to maintain. However, the subject gets to resist every time the spell is maintained. 
Time to cast: 10 seconds. 
Prerequisites: Magery 2 and two spells from at least 10 different colleges.

Energy cost to create: 2,200.
