So I hadn't posted on here in a while due to lack of internet and I just posted this in the wrong area. Anyway, I'm about to start running a new game which is going to start in a prison similar to Alcatraz. So one of my PC's instantley thought he needed to play a Rogue and since he's relatively new to the game he asked for some advice. So, I look through some of my stuff and stumble across the Underhand talent while looking at the Bandit Rogue variant.
Anyway, seeing that he could potentially deal maximum sneak attack damage with a concealed weapon, which he gains a nice bonus to concealing, made me think there was quite a bit of potential in this build. So I begin to look into it more and come across the Deft Hands talent which allows him to conceal a weapon in plain sight so he doesn't have to take a standard action (or move action if he has quick draw) to potentially deal maximum sneak attack damage to someone.
So we get to talking and he is up in the air between the Bandit for it's 4th level ability and the Knife Master for more bonuses to concealing weapons and increased damage potential from sneak attack. As for what he has, we're starting at 3rd level, he is playing a Gnome (this is a must as he's playing his old character from my last games illegitimate son) and his ability scores are as follows - str: 13, dex: 19, con: 12, int: 18, wis: 14, cha: 18 (I had the PCs roll 4d6 reroll 1s and if they roll four 6s they get a 19 or if they roll four 1s they get a 20). As for everything else, I was wondering if anyone had feat/talent progression suggestions. I was thinking weapon finesse, combat expertise, and the feint tree but I'm not sure if there are better options.
