Rock is a resource just like grass or branch. Keep your resource window opened and walk somewhere where the ground texture indicates rock, usually on riversides. Granite and limestone counts as rock, so when it appears in your resource window just click on it and you will start to gather.
Thanks i had like 10 limestone in my pack!!!!! brilliant when i get home from work ill try it out!!
You're most welcome If you want a campfire, you can build it with your limestone, but to fire it you will need flint and a blade too. Flint can be found on rocky surfaces, it randomly pops up in the resource window. A hunting knife works as a blade.
I believe you'll only find flint in areas with granite rocks.
I love the fact that each type of rock looks so different visually. As you explore, you'll start to recognize basalt veins in granite mountains, or limestone veins, etc.
It seems many of these different types of rocks have a secondary resource associated with them. Won't give away the spoilers if you want to have the surprise but keep an eye on that resource tab as you walk around
Have fun and welcome!
ps... if you're having too much trouble tracking down some flint and want a fire to chill by, contact me in game and I'll throw a piece of flint your way if we're close enough. I won't aim for the face though .
CORRECTION: just found flint in another type of rock vein so it doesn't just have to be granite... my bad.
