You know, i'd be willing to writeup a Blackstaff sponsored magic. An interesting idea for a BBEG is a former Blackstaff who retained the staff's power and is now training a group of wizardly assassins called The Blackstaffs. And they become their own power under the Unseelie Accords, and try to steal the original Blackstaff from the White Council. Actually, that's not a terrible character concept for a wizard- an escaped apprentice of that Order, who wields this magic that gives him such a leg up on other wizards.
anyway, here's the Sponsored Magic
BLACKSTAFF MAGIC
