OP, I'm going exactly like you. I want a duel wield Cihper, and my stats are about the same as yours. I would like to have a gun to switch to in case I get low health .
I think medium armor will be the way to go, unless something special in the cloth department comes along. With low CON and cloth armor, I'm too afraid of getting wiped out with a couple good shots.
I'm trying to figure out what race to play as, although with the ability to reapply attributes, it doesn't seem that big a deal, except for the 18 cap. Aumaua would be nice for possibility of 20 MGT, but human also isn't too bad.
I think I am going to use my PC as the trap/lockpicker too since I will lack a rogue party member, so I will need to bump stealth and mechanics. I also like laborer to get mechanics up to 2 and give me some fatigue resistance.
