The phylactory is only needed during the transformation process, but afterwards it is useless.
Yes. The necromancer puts his soul into the phylactery, his body dies and then the soul flows back into the corpse from the phylactery. Obviously, the necromancer needs to prepare a ritual that will do all this automatically once he sets it running. Once his soul is in the phylactery, he can't interfere with the process, so it has to work right the first time!
Like Gez said, transferring your soul into something other than your own body adds an extra level of complexity and so increases the risk of something going wrong with the ritual. Would you really want to run the risk of being stuck in your phylactery forever?
By the time a necromancer is powerful and knowledgeable enough to become a lich, I doubt his physical appearance matters much to him any more. Having spent decades or centuries in the company of dead bodies and shunned by the living, corpses might even look more attractive than real people (at least the dead don't generally chase you with torches and pichforks).
Either that, or they all just want to get into Falanu Hlaalu's pants.
Hmm... I also remember in a previous thread the subject of the
Oblivion lich model's obvious lack of genitalia came up and someone (might have been me) suggested that self-castration might be part of becoming a high-level necromancer due to the powerful symbolism of destroying one's own capacity to create life and separating oneself irreversibly from the world of the living.
This would also explain Mannimarco's voice acting.
I'm talking about your own body, of course.
Home is where the heart is.
No, I actually meant like real weapons that just fly around and hack people up. That would be cool.
So you've been playing
NWN2 as well?
I think I'll write a story about a narcissistic necromancer who searches for a way to become a lich and avoid losing his natural good looks.
Personally, in that position I'd be looking into getting a vampire to bite me rather than lichdom. That seems to be the easiest method to achieve immortality without losing your looks. Just as long as you feed regularly, of course.
