Partially for new players, but also as more are introduced, inclusion of an artifacts rarity in it's description could help determine it's worth (to keep or scrap) to a player.

rarity can be somewhat measured by the scrap range on the tooltip... but i would like to see the actual rarity too.

I would think the artifact rarity number would be somewhat equal to the amount of artifact points needed to aquire it.

that is a big part in what makes it rare. the higher the points the harder it is to get.

what I'm saying is a framework for what the number should be. And what you said is the reason I think it is a good idea.

its not an idea, thats how it is. the # is the rarity. i think all the artifacts within the same value have the same chance of retrieval.
