Spawnling: Shin's frenzies would be about what you'd imagine; he essentially loses his higher reasoning and enters a beastial state of "fight or flight," wherein he can only comprehend feeding and his own survival.

I love it.

I would rather have stronger regeneration than overall durability. Purely to stay truer to my inspirational sources. We could make him no more resilient than a normal person, but with extreme regenerative ability.[/quote]
Hmm...well, the main thing I'm worried about is the regenerating limbs part. How about cauterization, any wounds that are burned shut or cauterized *possibly by acid as well, to give our villain a way to actually be threatening* will regenerate exceedingly slowly. That gives you the potential for being a tough opponent, but also for the enemy to learn from their mistakes and actively challenge you later on.
It's really just the regrowing limbs that throws me, the rest of it I'm fine with.

The charisma would be partly a strange, inhuman beauty, but I was also thing of granting him the power to dominate the minds of the weak-willed. Typical "vampire servant" stuff.[/quote]
He's a half vampire, the dominating part throws me for a loop and it also has the potential for removing some challenge to a lot of situations. I'd say maybe he can influence particularly weak willed individuals at best. I personally don't like it but if it's something you REALLY want, I'll leave the final say to Viridian, I won't be upset by it if she allows it or anything. The inhuman beauty I'm totally fine with.
