I was talking about the files on dragonage nexus. The ones on the other fourm here didn't work for me.
You just have to name the one you want to rewards.gda and it works just fine.
So, I edited it but it doesn't seem to be working for me. I moved the... lines to the quest that I hadn't finished. Then I finished the quest and still, it was not there.
So frustrating.
I experienced that as well when I tried to test editing the armor into a later quest. It seems like you have to do it at the start or it doesn't work, which is kinda odd.
