Based on the information on the Artifacts spreadsheet it looks like you're using the word Artifact as just a different way of referring to derivative gear from another series and not in the Ready-Player-One sense where artifacts are unique items with no replications. Is this true?

I can answer this one at least. We are using 'artefacts' as a catch-all term for items of all rarities; I raised the same query as you when this was in the planning stages.
