And Vampires are higher level then Liches now... while Liches aren't even dead... odd.
Someone's just not quite gotten that the 'Kiss of Asha' is supposed to be a metaphor, oh sorry it's my mistake, it was all completely literal all along.
These necromancers are a little bit too religious, not to mention a bit radioactive for my liking. But I've got an answer as ever.
In Sandro's campaign in Heroes III it is pretty clear that the transformation from living human to undead liche (proper) is a gradual one and Sandro remains partly "alive" for a long period (whole months). The end result is an undead corpse, frozen at some advanced stage of decay (it does not appear to necessary be a complete skeleton).
But it is pretty evident that spending eternity as a corpse is not a particularly appealing, becoming a vampire is more attractive as a prospect but also risk (you need blood) not to mention a lot less moral (not that the average necromancer cares, but if there were good-aligned necromancers they would be liches).
But unlike with liches, vampires consume a finite resource, which is blood. The coveted position of vampire then is restricted by limited resources, to put it bluntly only the richest necromancers can 'afford' to exist for eternity as vampires since while there can be infinite numbers of liches, only a finite number of vampires can exist.
The exact mechanism by which the transformation to liche is carried out is not mentioned, the Necromancers of Ashan may use those spiders because they make the transformation very slow, as they are hoping to acquire the resources and status enough to be allow to become one of the civilizations vampires before it's too late.
