Let me copy-paste Tin's suggestion from
here:
"The "Food" based healing scheme is fine in and of itself but I think it needs a little more.
Why it needs a bit more is because of the "survivor perk", you are being a bit punished if you purchase it (in that you remain full for longer periods of time with every point).
[Minor Exploit] Wouldn't it be better to not to put any points in it so you could heal more often <.<!
Food/calorie heal: like it is now.
Vitamins: Give a in game 24hr slow heal 1hp per in game hour. (24hp per day)
Wellness above 50: Again a 24hr slow heal 1hp gain per hour. (24hp per day)
(minus the food) with vitamin and wellness heal you will gain 48hp every day. (48hp per day)
Counters -
Bleeding: Negates all except med's till fully cured.
Infection: Negates wellness hp gain till fully cured, (stage2): plus negates vitamin hp gain, (stage3): negates all except med's till fully cured.
Broken leg: Negates wellness and vitamin hp gains till cured fully.
Leg (splinted): Negates wellness hp gain till fully cured.
Food poisoning: Negates all till fully cured (minus med's of course)
Dysentery: negates all except meds till fully cured.
I am sure I am missing something but this is off the top of my head of possible type things. I am sure somebody will have better..."
