Not the faction, but the actual item. I never have enough of it and I'm starting to tap most of my settlements dry... and that was just to build up Sanctuary. I'm doing a really thorough playthrough with the settlement system right now and I'm setting up some major hub areas and then building up the other settlements to be more rustic. As of now, I will have 3 hubs: Sanctuary, County Crossing, and then the Castle. Sanctuary will probably be the most extensive, but I'm planning on pouring some time into County Crossing too. I just need a good source for steel that I can farm more or less. Do scavenging stations provide it for you or do you guys have another source you like to use?
