If you want a throw down I should bring in Vincent Valashar, BGWar. Vincent Valashar is a Mage Blade variant (from Monte Cook's Arcana Evolved) which he doesn't game spells but Arcane Battle Feats ever 3rd level. He crafted his own sword type (its a cross between a Scythe and a Greatsword (2d6 19-20 x3)), and was tied to the the campaign's equivelent to the Positive material plane. He could pretty much instantly heal himself or anyone else if he rolled good enough on his Heal checks.
One of my favorite moments with that character is that he charged in to a fight, killed the enemy leader (a fairly moderately leveled Gnoll with full health, critical hit with Power Attack :D ) with one hit then screamed "Surrender!" most intimidately. Lets just say the others dropped their blades immediately.
