Couldn't figure out a good name for this one, but this is (I think) the highest consistent damage build that can be made with the current PRC options. The damage output is absolutely ludicrous and in my testing it kills ALL enemies at a faster rate than a devcrit build can kill enemies susceptible to critical hits. Best of all, this build can inflict this massive damage every single round without limitation as none of the abilities are use-limited.
What this build gives you: 16 pre-epic BAB; great attack bonus (Lolth's Meat and Blood in the Water); absolutely enormous damage output - between soulmelds (Necrocarnum Weapon, Incarnate Avatar, Bluesteel Bracers), feats (Lolth's Meat, Cobalt Power), and maneuvers (Dancing Mongoose, Raging Mongoose, Blood in the Water) this character can average ~3000 melee damage a round (~3600 if you begin combat with a pounce) and ~925 on a single pouncing charge***; the damage caused by this build is persistent and not constrained by abilities limited to times/day; you also get a couple decent necrocarnum zombies (Necrocarnum Circlet) that you can summon at-will to serve as meat shields to keep the enemies off you; persistent 50% miss chance (Fellmist Robe); infinite essentia at level 8 (Harvest Soul) so your melds will always be maxed out; the ability to heal once per minute when recovering maneuvers (Vital Recovery); the ability to adapt to the best weapons you find (Weapon Aptitude); INT to reflex saves, crit confirmation, combat maneuvers, and damage against flat-footed enemies; the ability to instantly clear status effects (Ironheart Surge); uncanny dodge; and no level adjustment with this build
Weakpoints: not the best AC (Midnight Dodge will eventually help) or base saves (though Lolth's Meat mitigates this short-coming after a few kills) - get equipment to boost AC and saves, as well as equipment that gives immunity to status effects; you lose a small amount of damage output against non-living opponents (Necrocarnum Weapon), but the difference is small and won't slow you down

Recommended Martial Maneuvers: Pouncing Charge, Dancing Mongoose, Raging Mongoose, Iron Heart Surge, Blood in the Water (Stance). You could also take more Warblade levels in epic, at the expense of 1 point of meld essentia capacity at 40th level, to get additional diamond mind maneuvers: Diamond Defense (best defensive saving throw ability in the game - will totally eliminate any problem with low saves), Time Stands Still, and Avalanche of Blades. This is likely the way to go.
Recommended Soul Melds: Necrocarnum Weapon, Incarnate Avatar, Bluesteel Bracers, Necrocarnum Circlet (bound), Fellmist Robe (bound)
Notes: as a general strategy, this build should begin combat by charging the strongest opponent, initiate raging mongoose as soon as possible, then initiate dancing mongoose, recover maneuvers, repeat. Always make sure to recover your maneuvers immediately at/near the end of each combat - otherwise you will have to wait a full minute while they recover.
***Damage calculations updated after the scripted combat system was updated to pull in all the damage boosts. They assume max level, enemies that are alive and not crit-immune, that the player took the advice in the recommended maneuvers section and picked up Time Stands Still, and +20 damage from Lolth's Meat (which seems like a good average that I am doing in combat-heavy modules).
