Build a Sorcerer Warmage Dread Necromancer Beguiler.

[Beheld]

Astral Projection, while strong, does not seem part of the Dread Necromancers thing.

This is ultimately the thesis argument of your entire project:

The thing that 100% of Dread Necromancers do that is powerful and Necromanctic is not part of the Necromancers thing, because I need to define away 3/4ths of each class to get even close to pretending this ****ty Sorcerer can attempt to approximate these classes.
