I'm doing Doric's tasks, or attempting to. I need an iron full helm +1. I can make the helm, but I can't figure out how to make it +1. The RS Wiki says, "Add two iron bars to the iron full helm." That's all it says. Things I have already tried:
1..."Use" iron bar on iron full helm. Results: Nothing happens. Repeated this step twice with different iron bars. Same results.
2..."Use" iron full helm on anvil. Results: Makes another iron full helm, but not +1. Repeated a second time and resulted in another iron full helm. None of them are upgraded to +1.
3..."Use" iron full helm on furnace. Results: Makes another iron full helm, but not +1. Repeated this step with original helm with same results. Repeated with second helm made with same results.
I world hopped several times and asked at GE and the Lumbridge bank chest. No one seems to know. I asked my friends on the Friends List. They don't know either. I'm so frustrated, I'm considering not doing the tasks.
Can someone clue me in on how to do this?
