Just think of them as ablative "plot armor." It's what they're there for, so characters can be other-than-posthumous heroes.I know Hit Points is the best we have, but they really do not make sense in a lot of cases. Its just one of those things I try not to think about too much.
Frankly, I think it might just be easier to recover half the hit points lost in an encounter with a modest rest after a fight.
As good as dead? That depends on where the arrow hits you and how. If they managed to avoid infection (and rarely has D&D delved into that level of realism), plenty of people have survived arrow wounds throughout history. Just because an arrow inflicts hit point damage doesn't mean it skewered you through the vitals. Maybe it nicked your arm or leg (maybe even your ear). Perhaps it was tumbling through the air as it hit, leaving a welt. Perhaps it shattered on some armor or other obstacle and bits of wood and fletching got in your eye.
Sounds like the pre-4e system where you roll your hit die each level and gain that many max HP. I think it's a given that there will be a non-random option.Sorry for being dense but I don't get it... Does this mean you'll have hit points separate from hit dice in some way? Or will have to go back to rolling for hit points every level??
The advantage of hit dice is following:
A healing spell now can say:
cure light wounds: recover 2 hit dice+your level. Much less clunky than 20% of hp. Also better than healing xd8 (which does not take into account that a barbarian with 3 damage is differently injured than a wizard with 3 damage).
So what we've got here seems to be that we're keeping healing surges, but not by name, and only as a limit on non-magical healing. Other baggage of healing surges (like energy drain attacks) may also no longer apply.
I don't like the way the new HD mechanic is looking. It seems like it is a healing surge, but worse because of randomness.
I really want to see the condition track sneak it's way into 5e somehow, but that's not really related to hp.
Oh, and would this work better or worse with rolling HP vs. fixed HP?
Hooray for having no real choice but to have a healer?
