Please review this concept and the information within to further understand my talking point....
This skill will feed off of the Firemaking and Smithing skill primarily, I believe this addition whether it is added as a skill or addition to the firemaking skill will prove to be a very beneficial tool to those who are always on the move and don't have the patience or time to always tele back to a city or town. The smithing for this will be ONLY base level smithing, not specialty smithing that requires a special forge location. I hope that would keep the balance and not make this abused or over-powered. The more you level up your camp, the more types of smithing you can do, but never special crafting.
It will also add a level of immersion into the game for players who like to get lost in living in the world.
As I stated in the image I understand that its is a crude rough draft and not very refined, but I believe with a little help from the community in its refinement, I believe this will be a massive addition to RuneScape in the long run. With that said, I also think this would be a beneficial addition for OSRS without ruining immersion or other gameplay mechanics.
