After playing D&D for a while, and reading most of the Brilliant Gameologist handbooks, I've gotten to the point where I'm not satisfied with a build until its damage output has as many digits as its ECL (exaggerated, but not by much). I've spent so much time on 3.5 that I'm not going to switch to 4 for a while, so you can find me on the boards with all of the 3.5 optimizations.
Also, the username is because I love math, not because I especially like the Geometer PrC. I may find a use for it eventually, but to me, it doesn't have any real selling features.
