For this achievement you will need to craft the Hobo Stove in the “Shelter” portion of the crafting menu.
You will need a Barrel and a fire pit.
To craft an extra fire pit you will need to make another Campire using 4 sticks, and then craft the pit using 3 rocks on the campfire.
After that you will need a barrel. You can get a barrel from shipwrecks, they are bundled together and you’ll need a tool such as the axe or stone tool to break them apart. Keep in mind you can not “pickup” a barrel so you’ll need to either drag
it back to your island or put it on a raft and sail it back to your island. Hold
to move the barrel onto the raft, same as dragging.
Once you have the barrel take it back to your fire pit we had mentioned earlier and craft it next to the fire pit.
