Build for today. A divine caster gish monster that can serial crush with implosion. I love this build because of how clean it is. You don't really lose anything compared to a base cleric but you gain a ton. Even the epic feats and epic bonus feats line up perfectly. It seems like these 3 classes were meant to be combined in exactly this fashion.
What this build gives you: full cleric casting with no loss of caster levels and extremely good SR penetration; cleric buffing and healing; 17 pre-epic BAB for 4 attacks/round; 35/40 undead turning; devastating critical at level 21; extremely high save DCs for their spells, particularly evocation (implosion will end up with DCs in the 50s with WIS-boosting gear); heavy armor and tower shields; and uncanny dodge.
Weak points: only constructs with magic immunity will give this build trouble - it can devcrit or implode anything else; AC on this build is decent due to heavy armor use, tower shields, armor skin and racial natural armor bonus but is not godly; saves don't really get any notable boosts - be sure to mitigate this shortcoming with the best save-boosting equipment you can find.

Spell Suggestions:
- Implosion: instant death to everything, even those things immune to death magic, in a medium-sized area
- Sun Burst: huge damage to undead and permanent blindness to all
- Aura Versus Alignment: protects against some nasty status effects like fear and paralyze
- Hammer of the Gods: a good mid-level battlefield control spell
- Sound Burst: good low-level battlefield control spell
- Buffs: the cleric's real strength. Some suggestions, and remember you have Extend Spell to stretch them out: Divine Favor, Righteous Might, Battletide, Prayer, Recitation, Freedom of Movement, True Seeing, Premonition (fate), Mantle of Egregious Might (war)
- Recovery Spells: Heal, Lesser Restoration, Restoration, Greater Restoration, Regeneration
- War Domain Spells: keep one copy of the highest War Domain spell you have available prepared at all times to maximize the damage bonus from Holy Warrior
Note, make sure to buy off the half-ogre level adjustment as soon as you can (level 6 and 9). Because all the active abilities in this build are in the vanilla game, this one makes a great custom cohort. If you are OK with a high level of cheese (and have level adjustment turned off) you could switch Lightning Reflexes for Craft Wonderous Items at level 15 and you would then qualify for the lich template and the demilich template at level 21. You must be lawful evil or neutral evil for that though.
