Disabled is more fun and dramatic than "Dying". Want to extend that range in both directions. I start characters at lvl 3, give max hit points and like that the disabled range stays constant as they level. You may only want it from 0 to neg.
You are disabled when your hit points equal from HD to -Con mod.
A 5th level character with 16 Constitution (+3 Mod) would be disabled from +5 to -3 hit points, dying at -4 through -15 hit points and dead at -16 or less hit points.
Similar for non-lethal and staggered.
