The idea is that you use helf double diplomacy to keep shedding aggro and increase your ability to use your 3d6 sneak attack dice. Also lots of other goodies.
One possible point of contention is I used leveling stat raises into cha to qualify for DM 3. My reasoning is that 2 cha and dm3 vs 2 str is the same as for using power attack. You lose 1 hit, gain 1 damage also you gain an extra DM use, 1 to all saves, +1 smite dam, etc. Obviously you would put your points into str if you were a TR or had a +3 cha tome waiting for you.
IMO the survivability of evasion + the extra feats are worth giving up the capstone and divine sac 3 as nice as they are.
The only tomes required are a cheap +1 cha and a slightly more expensive +2 dex. Others are just gravy. At 28 points you would lose 2 initial STR. I wouldn't recommend this build if you don't have 32 points but I don't think it is that big a deal.
