As I recall (and I've not read the rules in decades) a PC could buy down the damage Quality to survive otherwise fatal attacks. A plot immunity mechanism that worked well for a James Bond RPG.
Some RPGs ask, "How good/powerful is the weapon?" and others ask, "How good are you WITH using the weapon?". A typical D100 system asks BOTH those questions in reverse order with a hit roll, then damage roll. I'm not so sure they should be quite so separate.
