Vecna wouldn't really have a choice because it would have been one of my low level believers that was vecna blooded. By the time he realized what was going on the believer would have already been part of me. He could then come after Azrael, but he would lose horribly.
That being said I think we have established I'm no longer vecna blooded because of the problems it would pose with cop.
And thanks, the character has been around since 05-06ish so I cant say how long it took me, but it didn't reach this final form until this week. I had been meaning to update it when I realized, 'hey, I can thrallherd a thrallherd' (and I added more abilities). The update took me about a week; on and off of course. Calculating all the feats, hp, skills, pp, etc (not that most of them mattered anyway) was the most time-consuming part.
