Optimized Character Pair

[Overshee]

The Wish and the Word were created for a WotC Character Optimization board challenge several years ago. The challenge was to create the most optimized pair of characters. They were disqualified for "going overboard", and at the same time won Honorable Mention. At the time, this was probably the most powerful 'theoretical' optimization. The build was erased from the WotC boards in one of its many moves, so it is now placed here until the end of time. The text has not been changed from its original post.

I found The Wish and the Word on the DnD Wiki while looking for a build guide to two optimized characters meant to work together. While this one is a bit (waaaaay too) cheesy for us, a friend and I are looking for a duo to play as. The link to "The challenge was to create the most optimized pair of characters" (IDK if it's been lost in the ages), or some suggestions would be great.

Thanks!
