I still believe that some kind of "energy bar" is best solution for this problem. :-/

It should be deplenishing by small amount while walking and talking, and by moderate amount while fighing.
It should be replenished by a little bigger than small, but also not as big as moderate, amount with short rests.

It limits use of long rest, since you cant rest until your party "get tired" ...
It forces us to use long rest, since you should be uneffective in fight when "tired" ...


I still dont understand why cant we change Race for our hirelings. frown
Lets us play Githyanki as racist as they trully are! frown
