This is an odd choice at best. It's also doesnt have a variety of clear paths. Its abilities are powerful for a party of necropolitons, and you almost need to be undead just so an unlucky dispel does not end you. You have great stats if somewhat unfocused. Your abilities lend towards minionmancy, and are reasonably powerful. Dread necromancer seems maybe the only solid path, with some flavor of undead bard also maybe doable.

Still pretty good undead minionmancy out the box with no component cost means most encounters are just extending your army. I think like a +2, because assuming a competent party built so you are not a detriment, it has near limitless minionmancy and stellar stats and tons of great stuff. Not sure however and I am swayable.
