So, playing around with the skillcalc...

This build should work relatively well up until (and possibly through) Hell mode. At that point you can rename Death Blossom to Death Wish. I predict the farther you get into the game with this build the less and less you actually use that skill. It is extremely fun, but the negatives FAR outweigh the positive of big damage. Every other skill has at least some modicum of viability in an end game build.
