The altered special attack and special quality look quite solid to me.  Everything I’d want to say about them has pretty much been said by other people, and overall it looks like a solid couple of alterations that should work quite well for Methu.<br/><br/><div class="quoteheader"><div class="topslice_quote">Quote</div></div><blockquote class="bbc_standard_quote">Vampire Lord always creates Vampires -- never Vampire Spawn. I also thought, at first reading, that Vampire Lord had no cap on HD of enslaved Vampires, but now I'm questioning if that's true...</blockquote><div class="quotefooter"><div class="botslice_quote"></div></div><br/>I thought the same thing, but looking over the official source for the Vampire Lord template (http://archive.wizards.com/default.asp?x=dnd/mm/20021018a), the section on Create Spawn doesn’t actually contain any language for removing the HD cap from the regular Vampire template.  I suppose the best option would be to transform most of the creatures you kill into Wights via your Soul Eater class feature, while saving vampirism as a reward for a particularly favored servant or powerful enemy.
