So, I'm planning a trip to the planet Lundunder next session. Firearms are strictly prohibited in the 'hanging cities' due to fear of breaches (as per Inquisitor's Handbook ), so Landrians have developed elaborate knife-fighting techniques over the centuries- similar to the way Asian peasants invented the Martial Arts to compensate for their lack of weapons in areas plagued by bandits.
Sounds good, but in looking over the melee-based Talents in the Core Rulebook , not a whole lot is jumping out at me for representing 'deadly knife-fighting arts'. There are extra attacks and parries, of course, but I'm not seeing anything other than Crushing Blow (+2 damage) and Street Fighter (extra Critical damage) that would make knives more than just a joke to heavily-armoured PCs, even if they have the 'mono' upgrade.
Does anyone know of any existing gimmicks that I can use to make knife-fighters a legit threat, or do I need to house-rule a new Talent? (Like, say, Landrian Knife-Master: the character adds his Agility Bonus to a knife's Penetration value...?)
