Can you make an axe out of wood and stone that is capable of chopping down a fully grown tree?
What about wooden frames that can be stacked 20+ high and hold the weight of a fully grown adult?
What about a door? A ladder? A storage chest? A pipe shotgun? Can you make any of those?
If the answer is no, and you don't think your character should be able to either, then this is the mod for you!
This mod makes absolutely everything in game require learning before it can be crafted!
