~ 45 minutes in, we get 5e's first "bag of rats" moment:
Folks mention you can use Second Wind over and over again to heal all your HP.
Mearls notes that since you need a short rest to regain it, this becomes kind of inefficient (if you can take that many short rests, you can basically heal up to full anyway), but is totally something that 5e is comfy with letting you do if you want. There's guidelines for wandering monsters in the Starter Set, and a WP/VP system present in the DMG (take damage, and your max HP goes down).
It's a "bag of rats" moment because it's a little rules technicality that most DMs will probably deal with effectively, but that is something that is RAW-OK.
Weird that everyone seems kind of hostile to the idea of using it like this -- instantly kind of thinking of ways to tamp down on it or ways that it's not "really" effective, but it does not seem like an issue to me to have a fighter burn their Second Wind to help heal their HP before or after a rest.
Sounds like there's no real codified cost to resting, just DM judgement calls, which is a little unfortunate....
There's a bit of a philosophical insight into how having a monster that the characters aren't likely to be able to beat in there changes the feel of the game. Really nice.
And apparently Nothics are considered iconic, essential creatures now? Bah!
