So the way that two weapon fighting works in Edge of the Empire is you take an extra diffculty dice, and then pay 2 advantage or 1 triumph to hit with the secondary weapon, which in this case is a fist. Each attack does damage equal to base damage + uncancelled successes.
Unarmed Fist: Brawn, Crit 5, Disorient 1, Knockdown
Vibroknucklers modified unarmed by adding: +1 damage, Crit 2. Pierce 1, Vicious 1.
Attack on the troopers:
3eA+1eP+1eF+3eD 5 successes, 2 Light Side
Well. That is some dice. Force Enhance allows me to turn those 2 Light Side points into Advantages so I can get my secondary attack to hit too.
So. Primary attack is 10 damage, secondary is 9. I....did not expect to roll that many successes. Clearly the troopers were more unsettled by my speech than I thought.
Sorry for taking a while. Been helping brother through some stuff with his job and it's taken up my evenings.
