Wield Spiked Chain as double weapon?

[Barachiel Shina]

I may be mistaken entirely, but I thought there was a build out there that allowed you to wield a spiked chain as if it were a double weapon?

There was a prestige class back in 3.0 (the master of chains, Sword and Fist), but that's a little antiquated at this point.

You might try wearing a chain coat (Adventurer's Armory 2) or selecting the Chain Mastery feat (Book of the Damned). You'll still need a way to negate the oversized two-weapon fighting penalties and two spiked chains, though.

It's not perfect, but we do what we can. ^_^
