A couple years ago I posted my alt assasin on these boards.
Same BAB (Rogue)
Same HD (d6 Rogue)
Same Saves (Ref Good, rest Poor)
Same Skills (4 + Int, same list)
No Spells
Sneak Attack +7d6 over 10 levels (the 3 levels you don't get sneak attack damage, you get nifty assasin ability)
Unfortunately, I honestly don't remember the nifty assasin abilities. I prefer modular PrCs which force choice abilities, so I think there was at least one level where you had to choose from a list of abilities. Here's some examples:
1: Sneak Attack +1d6, poison-use
2: Uncanny Dodge, Ability*
3: Sneak Attack +2d6
4: Sneak Attack +3d6
5: Sneak Attack +4d6, Improved Uncanny Dodge
6: Ability*
7: Sneak Attack +5d6
8: Sneak Attack +6d6
9: Sneak Attack +7d6
10: Ability*
*- There were a few paths, along with some nice misc assasin abilities.
-Poison Path-
A. Poison Resistance- you gain a bonus to save against poison equal to half your Assasin level (round down).
B. Poison Specialist- there is a 50% chance poison you apply to a weapon (and then wield) will remain on the blade an additional round (allowing you to strike without reapplying).
C. Poison Master- You can distill/extract a more powerful form of a poison. This requires 1 hour of uninterrupted work and access to an alchemist's lab as well as 2 vials of the poison. The resulting single vial of poison has its initial and secondary DC improved by 2. Additionally, your Specialist ability is always 100% when you use these poisons.
-Death Path-
A. Death Attack- As, DMG Assasin.
B. Quicken Death Attack- 1/day you may make a Death Attack after only 1 round of study.
C. Marked for Death- 1/week you may study a subject and launch your Death Attack anytime during the next week. You may not use this ability with Quicken Death Attack. If you study someone else, you lose the original target.
-Misc-
Improved Evasion- Requires Evasion.
Sneak Attack +1d6 (can be taken more than once)
Provaceur Skills- You get the ability to take 10 even under adverse conditions with Hide, Move Silently, and Disguise.
Something along those lines...
