Ok, to clarify, I nearly break out in hives when I play a pure caster. The book keeping scares me off, as do the huge amount of options. Bearing that in mind...
Do you think taking two levels of Dread Necromancer, and the tomb born soul feat is a solid investment for a melee character. The benafits I see are a nice spell list(in armor), DR 2, free out of combat healing, and rebuke undead. Cons would be the d8 HD, losing one point of BAB, and not being healed by positive energy.
