Yeah. This is working real well.
1. Allow unlimited Short Rests.
2. Short Rest Cost 1 Camping Supply per Point of HP healed during rest.
3. Each player chooses Camp Supplies they wish to spend per Short Rest, so they don't have to heal to full. Minimum 1 Camping Supply per Short Rest per character.
4. Arcane Recovery only able to be used during Short Rest, and reminder to use it would be nice.
5. Long Rest Cost 5 Camping Supplies per Character Level at camp (extras like Volo don't count).
6. Dialogues tied to Short AND Long Rests, and characters transported to camp when Short Rest also for dialogues and to show you ain't just healing somehow on the fly. You are pausing your adventure to rest.
