Would be a great idea for a Dawnguard Expansion mod... Find out a that there's an "inner circle" of sorts, and that the VL you face is just one of said circle.
Does sound good.. Though unfortunately I have a PS3

I think one thing the game could do with improving on is enemies with vastly different abilities - and adding higher level versions of enemies that are truly different and fearsome.
So thats why I was hoping to fight hordes of VLs - bit of variety.
Normally the only differences in main Skyrim between a vamp and a typical enemy mage is the use of a drain life spell and the use of a thrall or two (which necromancers do anyway). Only differences between a low level vamp and a high level vamp is the damage they do and their HP.
