1. Allow unlimited Short Rests.
2. Short Rest Cost 1 Camping Supply per Point of HP healed during rest.
These 2 combined will basically make it a full circle and bring us back to when pig heads were used for healing during combat. Well, almost.
Besides, I don't think it will work well in end game. If I'm a level 10 fighter missing 60 hp, does it mean that I'll have to drink 10 bottles of wine within 1 hour to fully heal myself?
