Hello and welcome to nomads shop here he sells all sorts of stuff and even some really op things. In order to get something you need to make a trade, op items are only available when you give him a rare item that he will give you anything for like bio-mechanical heads, jems or crystals, and exotic plants. Knowing this you can pick from two options a fuse or a helpful raven that can carry you anywhere fast, but there is a item that you can get that is more powerful than anything in the game it’s nomads saddle. With this item you can ride anything as long as you could actually ride it this item requires you to bring shadow to nomads shop. Then you will get the achievement “together at last” or something I’m still working on it.
