Novocrane, the whole discussion right now is about stacking bonuses from multiple pieces of gear. It started with concealability modifier bonuses, and has moved on to Social Limit bonuses and wireless bonuses. My argument is that none of those should stack. The only argument that I could see making sense is to allow those bonuses to only stack with gear that already qualifies for the Custom Fit (Stack) rule. The alternative being proposed is that the gear should be able to stack to "within reasonable limits." My argument is that saying "reasonable limits" is pointless - someone's going to cry and bitch and moan when the GM lets someone stack three pieces of gear but not four. To me, the "reasonable limit" is the Custom Fit (Stack) rule. This eliminates all need for explaining to your player why X and Y gear can stack bonuses, but X, Y, and Z gear can't.
Under my scenario, a character wearing an Armante Suit with a Mortimer of London Ulysses Geat Coat would get the following:
Armor Value: 10 (only the coat applies)
Encumbrance: 0 (the coat doesn't grant added armor to the suit or vice versa)
Social Limit Bonus: +2 (from the suit, since it's the higher of the two and visible)
Concealability Bonus: -3 (from the coat, since it's the higher of the two)
Wireless Bonus: +1 (from either piece of equipment)
Additionally, the following would happen to a character with a Mortimer of London Berwick Suit and a Mortimer of London Argentum Coat:
Armor Value: 13 (9 from the suit, +4 from the coat)
Encumbrance: +4 (from the coat)
Social Limit Bonus: 1 (from either piece of equipment)
Concealability Bonus: -5 (-2 from the suit, -3 from the coat)
Wireless Bonus: +2 (+1 from the suit, +1 from the coat)
Also, just found this totally handy tidbit from the full-page sidebar on page 59 of
Run & Gun:
SOCIAL LIMIT MODIFIERS
The value and status of simply wearing certain outfits help characters impress those around them, while on the other hand wearing camo fatigues at a social gathering isn’t the social standard. Some pieces of armor raise the Social Limit of the wearer.These modifiers do not stack; only the highest modifier of any visible clothing item counts (and “visible” means seeing enough of it that viewers get a solid impression of what the garment does on the wearer. Seeing, for example, only the edge of a cuff poking out from under the sleeve of a battered overcoat or the hem of a dress beneath a housecoat will not provide the modifier). Some increases are limited to certain social circles; those limitations will be listed along with the bonus.
