One idea I have had for some time is about being able to craft healing items like remedies, medical kits etc.
To craft a medkit you will need: 5 dressing, 3 bandages, 1 antibiotic, 1 blood bag, 1 backpack, the crafted med kit cures 15% less than a normal medical kit.
Blood bag:This probably should be the strangest of this topic, so you’ll need 1 empty bag easily found in hospitals and an all of transfusion that is unusual but comes in x5 piles, the concept is that you fill the bag with your own blood which means that to craftala you will lose life, each one cures 65% of life or it is recommended you have a base and a bed to not regret to craft one of these blood bag.
Dressings and bandages:use the current concept and method of craft using cloth.
Remedies and antibiotics:For craftalos you will need a laboratory and a medicinal plant, the medicinal plant can be raw food besides used for diverse recipes combined it with different ingredients, in the case of the antibiotic it is necessary to have an laboratory that equipments, like centrifuges, Microscope and etc. , mixing different amounts of the medicinal plant with berries will have antibiotics and remedies depending on the berry They resulted in different advanced remedies.
