Sith Marauder - Wlk(16), FB(5), BG(4), DC(5)

Description
'''Warlock 16 / Frenzied Berserker 5 / Blackguard 4 / Divine Champion 5

Alright, it's not a real Sith build obviously, but it did evolve out of my attempt to create one that resembled a force-user. The Sith Marauder uses warlock invocations to add some nifty abilities to some combat classes with their own nifty abilities.

Pros
 * High Saves
 * Decent damage reduction (natural Warlock DR, achieves 1 dark invocation - Dark Foresight is highly recommended for both utility and flavor)
 * Epic Divine Might and Enhanced Power Attack for high damage potential
 * 26BAB - full 6 attacks
 * Divine Shield, Force users are supposed to be dodgy
 * Loads of assorted goodies like Superior Cleave, Walk Unseen, Devour Magic, Divine Wrath, Deathless Frenzy, etc.
 * Good UMD

Cons
 * Not as powerful as plenty of power builds, Warlock as a base in many ways loses out compared to, for example, Cleric as a base
 * Unremarkable PvP abilities
 * Warlock spellcasting limitations, unremarkable Eldritch Blasts
 * AB and AC are fine, but not great for a melee build
