Dont forget all the food you find all over the world - pigs head & other meat cures more than a cure light wounds & you can eat two items during combat from your inventory - im carrying enough now that I wouldnt need Shadow Heart - but in this playthrough im using her ...fruit does the same dont discard anything - carrots, garlic, potatoes...even some grilled unsavoury meats the goblins have all works....well 99% does....
