I suppose I should have been clearer that some exceptions now exist: Again though, if hit points are an odd amalgam of grit and determination with luck and divine favor, why can't you use them to overcome fear and mental control or to dodge a poisoned dart, etc.?
You can. What do you think keeps you on your feet, fighting against the mental control or the poison? It's only when you hit 0 HP that you've really succumbed to the effect.
And if a morale-boosting rallying cry from your inspiring leader can "heal" hit points, why doesn't anything and everything that's scary or demoralizing do "damage" to hit points?
You can do this, too. Page 42 tells you how much damage you can be expected to do with, say, an Intimidate check.
