how do you find scraps?
warning- some spoilers included in the answer.
After Ashfall is killed, talk to Sunstar and he will tell you to go talk to Bushstep. After going to the medicine den, talk to him, and follow him into his den. Pick up the pan, go to the river, into your inventory, click the pan, and there should be something along the lines of ‘use’. Maybe. I haven’t played the game in a while.
