If we're posting absurd builds, I've got one.
Athasian Bard 1/Swashbuckler 1/Sorcerer 1/Warlock 1/Initiate of the Draconic Mysteries 1/Holy Liberator 1/Abjurant Champion 1
I was aiming for a Fochlucan Lyrist that advanced Warlock and could finish the class pre-epic. I actually had a pretty good story, too. Primordial Half-Giant, so I was going to have him have been a former (dex-based) slave gladiator who managed to escape, nearly died, saved by a good-aligned green dragon, standard nursed-back to health cliche here, and who then became devoted to a life of freeing other enslaved "monstrous" races, and looked up to his draconic mentor as the ideal role model, as a balance of the oft-opposed aspects of the arcane with nature magic. I wasn't going to finish Abjurant Champion, but who the hell cares, I'd get the quickened abjurations (yay for Shield and Mage Armor, which was houseruled abjuration) before leaving, and have you SEEN the chassis on Fochlucan Lyrist?
On topic, have we talked about the Rainbow Servant yet? Cause, yeah, that one's badass under very specific circumstances, otherwise not so much.
