So, I've recently been planning out a way to make a brawler character. The idea came tome while I was creating an eccentric dueling droid (I have a habbit of making character sheets I'll never use to come up with ideas), and thought, "How could I make an awesome brawler character?"
The answer is a Trandoshan Bounty Hunty Gadgeteer Maurauder Commando with Jury Rigged brass knuckles and shock gloves, the brass knuckles also being Tinkered, so that they can both get Superior, and also getting five ranks of Feral Strength between Maurauder and Commando, and getting Detication to increase Brawn to six, as well as increasing Brawl to five for easy rolling.
Wow, that was a mouthful.
This ends you up with a super buff murder machine that dishes out a whopping seventeen wound and three strain damage in attacks, or twelve without weapons. However, if you go for the gusto and take the whole package, it costs an equally whopping 390 experience, or around 245 if you just go for strength (it costs considerably less due to skipping out on a specialization and it's talents, but also requires you to buy a cybernetic enhancement and have less brawl). Of course, it costs a lot either way.
The point, though, is that it's possible, and from the one test run I've had with starting such a character, you're just about invincible if you get good armor and toughened/grit.
BUT STILL.
