Drain Magery (VH)

Regular; Resisted by Will+Magery 
Permanently drains one level of the subject’s Magery advantage. The caster must touch the subject throughout the casting. 
The subject retains his knowledge of spells (albeit at a lower skill level), but cannot cast those that require a higher degree of Magery than his new one. 
A critical failure with this spell costs the caster a degree of Magery and a point of IQ!

Duration: Permanent. 
Cost: 30. 
Time to cast: 10 minutes. 
Prerequisites: Magery 3 and Suspend Magery (VH).

Item 
There are persistent rumors of malevolent items that drain Magery from their victims, but nothing specific is known.
