Here is how you could distribute points for your Rogue, depending on how you play. I have added a list of famous characters in the Forgotten Realms and adjusted their ability scores with regards to NWN abilities scores, distribution points and modifiers. There is also some explanation of what kind of character you are looking at.
The Rogue of the Dales
This type of Rogue is quite the adventurer and as typical of the class prefers light to medium armour. Proficiencies with the short-sword or other close-combat weapons make his constitution healthy, and emphasis on stealth is important. Being of an adventurous spirit he can be quite the swashbuckler.
- Strength 11 (none)
- Dexterity 18 (+4)
- Constitution 14 (+2)
- Wisdom 8 (-1)
- Intelligence 12 (+1)
- Charisma 11 (none)
Rogues of the Dales are normally Human or Half-elven, but nobody is looking so you can play as an Elf.
The Sembian Rogue
Since Sembia is a civilized place and home to famous merchants or business men, this type of Rogue is mainly focussed on buying and selling goods or trading gems and valuables. They keep count of what they own, the price of their valuables and loot. As for garments, they prefer to wear expensive or moderately expensive clothing since this would imply their adeptness at trading. They are not particularly good fighters and favour long-range weapons.
- Strength 11(none)
- Dexterity 16 (+3)
- Constitution 11 (none)
- Wisdom 8 (-1)
- Intelligence 15 (+2)
- Charisma 15 (+2)
Looks somewhat of a ‘Shylock the avid’ to me, but a good merchant character to play nonetheless. You can even build him into a merchant prince should you wish to do so, with such high-charisma scores people will believe anything.
The Dragon Coast Rogue
As you can probably guess by its name, the shores of the Dragon Coast are not ruled by anyone in particular. The citizens of the various states like freedom, and the Rogues in this states are generally pirates or bandits who will not be easily stopped in their pursuing of riches. The Dragon Coast Rogue is therefore quite strong, favouring sword-like weapons, or exotic weapons such as the kukri. That being said, he has the usual ability to set traps and picking locks, although he prefers to bash a chest rather than lock-pick it.
- Strength 15 (+2)
- Dexterity 16 (+3)
- Constitution 14 (+2)
- Wisdom 8 (-1)
- Intelligence 10 (none)
- Charisma 12 (+1)
