How 'bout -
Gravity Well
Upon casting, a black orb 1 foot in diameter forms in the casters hands and floats to the target. Everyone (including the caster and his/her party) within 25 feet of the orb is "sucked" towards it at a rate of 10 foot per round. When they come in contact with the sphere they start to take 1d6 damage each round until the spell runs out or is dispelled.
Type: Conjuration (I think?)
Duration: 2 turns
Level: 8
Save: spells at -4 (once each round)
Also a "vampires revenge" type spell would be quite cool - Once cast, all damage done to the caster is instead "received" by his attacker. Have to be level 9 and it may unbalance the game too much... dunno?
