You're wresting my meaning here. The PHB definition is explaining in broad terms why the fighter falling 200 feet can survive. Celtavian's scenario is explicitly overruling the PHB because he finds the PHB unaesthetic in this particular case. I said that's fine, so long as your players know in advance that you're going to do that and that HP aren't 'real'. Do you disagree?
Yep.
A player that willingly jumps into lava has either lost the will to live, our run out of luck.
I'm sure the player will get from the look on my face as DM that jumping into lava is a bad idea.
Assuming he (for some reason) didn't already draw that inference already!
