I'm hoping someone might give me some advice for a Halfling Opportunist character I'm working on. I think this prestige has a lot of potential, but I can't seem to find anyone with the same sentiment. I'm a little stuck around level 9 unfortunately. My plan is to use Snakebite Striker as the base class so he can get a jump on Sneak Attack and have decent BaB early on, then move to Halfling Opportunist as soon as possible to get their capstone ability to abuse sneak attack on AoOs.
