Nothing that new here, this build focuses on being a near max caster, but with melee capability as a secondary mode of attack.

Pros:
Max caster ability (minus a couple of feats). Very good hit points, self healing, and some melee ability.

Cons:
Have to use divine power clickies to hit anything, melee DPS is not high at all but can contribute in cases where spell DPS does not work well.
