Masters of the Sword: A Warblade's Handbook [Under Construction]

[Optimator]

Deep Impact + Power Attack + Diamond Nightmare Blade is a fun, if gimmicky, high-level feat combo. Add in Instant Clarity and Psychic Renewal and go to town. A two-level Psychic Warrior dip can be really cool for Warblades. A four level dip gets you Hustle and 3 first level powers, like Expansion, Force Screen or Grip of Iron for instance. Add in Psionic Meditation and get slap-happy with your foci. A build like that still leaves you with an IL of 18, every Warblade class ability except Dual Stance (which is so hawt), and 4 stances at level 20. Takes a small investment like a wisdom item or Cognizance Crystals to have some decent PP. Not a perfect build but I think it's fun and potentially flavorful.

Also, another cool combo which has been, for the most part, mentioned already is combining Robilar's Gambit and Battle Mastery on a high-Int Warblade for the bonus on the AoOs. And yeah, forgoing the attacks using the Channel the Storm part of Stormguard Warrior is stupid good, especially when followed by a Raging Mongoose-boosted Time Stands Still.
