Ok, we will use the chicken (food +200) for this.
If you have a normal food +200 item, you can:
- Eat it raw - restores only 200
- Cook it over a fire - restores 300
- Bring it to a store for it to be cooked - restores 500
Mabey you can get a cooking skill so you can use just your fire to make it like a store would.
Saves time and money.
