2. No, +4 is always the cap.
so how does that work with customized cyberlimbs?
Is my character legal?
Melee Combat in a Wheelchair would pretty much be a -6 for you and +6 for the other guy
Where do you get that from?
And why wouldn't a superhuman cyborg get cyberlegs?
He wants to be role model for all the aspiring para shadowrunners..
Don't let your disability stop your dreams of reveling in murder.
Did Oscar Pistorius let his disability stop him?
Customized limbs can go up to Racial max, then up to +4 from Enhancements.
Sword Fighting in a Wheelchair is covered on p. 278 of the core book.*
And Oscar Pistorius got Cyberlegs, such as we currently have.
* No, no it is not. This would be GM prerogative as sword fighting in a wheelchair is going to be very challenging. -6/+6 is about the largest penalty a GM can slap on someone. Presuming you're in something even remotely like our current RL Wheelchairs you'll be unable to defend most of the chair and your legs. Legs may not work, but they still bleed, you've got poor leverage and a height disadvantage. Your opponent is going to have pretty much free shots at the lower/front of your chair, you'll get knocked sideways or knocked over much more easily. You're going to get knocked sideways and your weak side will be very difficult to defend.
From an attack perspective you pretty well give up a foot of reach. You've got a more limited arc you can use, your center of gravity is terrible. Sitting is awful for leverage.
Anyway. If you GM decrees that fighting from a wheelchair is no penalty rock on.
