At the start of your time in Last Oasis, you will be coming to grips with various systems in the game. As you learn to craft different items, you will need to harvest resources to create them.
Wood, stone, and fiber are all important resources that you will need to gather up in the game, so knowing where to find them is important.
At the very start of the game, you will need to gather fall wood from the ground. Just run up to the sticks of wood you will be able to see lying around, and hit F to harvest it.
If there are none in your spawn area, then a very short time spent looking around should yield some just a little further out.
After a short time in the tutorial, you will get access to an axe, allowing you to harvest wood directly from trees.
Stone can be found on the ground in the spawn area, and can simply be picked up by hitting F. The stone should be easy to see, as it’s dark surface stands out easily against the pale sands of the desert.
Fiber can be found by harvest bushes that can be found all over the initial spawn area. Once again, just hit F to harvest it.
Harvesting in Last Oasis is almost instant, with no real animation time spent, as you just pluck the resource out of the world and into your inventory. This makes harvesting a lot of resources quickly a very easy thing to do.
