Charcoal is one of the most important items that you will need to build up a reliable supply of early on in the game. Since thirst is going to be a constant struggle in this game, you will need to make sure you get plenty of charcoal as quickly as possible to be able to craft enough cola to survive.
Charcoal is created from cooking flimsy wood over fireplace. It will take a few pieces, however, which means that you will need to constantly be on the lookout for more timber to use for your water crafting.
How To Get Wood For Charcoal
There are a couple of different types of wood that you can pickup in this game. Early on, you will have to rely on flimsy wood in order to burn it in the fireplace to create charcoal. As you progress further in the game, you will come across better pieces of wood that will produce larger amounts of charcoal when you burn them in the fireplace.
