Jokes aside, this works because you have no other stats or attributes you have to change, just the resistance penalty. This would add extra steps to every character to adjust the penalty, adjust the health, add conditions, etc.

If it's a *replacement* to health, that works perfectly fine. If it's in addition to health, then it makes either this mechanic useless, or the health mechanic useless.
