Early on you will meet The Feral Child and he’ll tell you to fix his Workbench. You need 2 Sour Tree Branches for this, you probably have dozens if not close to 100 by now. One is near a wasp hive and the Feral Child will tell you to make Gas Bombs, these stun wasps in the Gas cloud as long as they last, equip them like any weapon and press
to throw. Kill the wasps or not, repair the totem by standing near it and pressing
to use the Sour Tree Branch item from your bag on it. Walk to the other one (no wasps this time) and do the same, then walk back to the Feral Child and turn in.
So you must actually craft something at the Workbench for this to pop, I’d suggest the Bone Machete recipe you just got. Stand near the Workbench and press
, highlight the item you want to craft (must have a Hammer icon, which indicates that the Workbench is required), hold
until it crafts and your achievement will unlock.
