I suggest the following: in the extended map editor, there is a table called ArtifactTableRef or something similar. When I was modifying artifacts to suit my needs, I saw prices, the type (Major), bonuses, effects, and so on. I also believe I saw the artifact identifier you're looking for. I might be wrong, but I created my own artifacts by simply changing Frieda, Tank, and the Griffin Heart each time.

There, you can also, by clicking on Add, connect and link all the references to your data.
I didn't quite understand... Did you always change only 3 artifacts? Or did you duplicate them and could create as many as you wanted? The thing is, the list of artifacts in Armageddon's Blade is quite large.
