So, you want to break the world in half? Shatter WBL into tiny, tiny pieces?

Make your DM break down crying?


Artificer.

The level doesn't matter, so long as it's above 9.

Your first few feats should be Apprentice (Craftsman), Legendary Artisan, and Extrordinary Artisan. Then pick up Magical Artisan for wondrous items, and for... Well, whatever you want to make dirt cheap. Then pick up Bind Elemental ASAP, and Landlord. Then make an airship of doom. For. Free.

Your party will love you. Your DM will... Not.
