Tried searching, and couldn't really find anything... D:
So I was just walking around in this cave, when I needed a fire to roast some raw meat i brought with me, and I was annoyed there wasn't any wood down there...
So I got this idea, what if we were able to find roots underground that could be lige a foragable that would require... dunno, like per*exp = 25-35 or something...
The amount of wood you get would reach from 1-2 branches, to 1 block of wood depending on your nature/industry slider, ofc, the nature slider would give you the most wood.
...Well, that's the idea.
