Pick a race which gives +1 or +2 in Charisma. Then, put enough points into Charisma to reach 16 (You could reach 17, but there's no benefit to odd numbers). You'll also want a CON of 14. You'll want WIS at 10 or 12, definitely not a negative modifier to that. Then pick either STR or DEX to dump, depending on the type of weapon you want to use.
