Hello, I've recently scanned a terra planet. It is small, :/, but it has 1x mega rich Artifacts. In Ctp, how much would it be worth, it's ok if it's nothing. Also, what artifact costs the most artifact points? I'm asking this one because i have just received a massive storage pod or something @20k ap.

The small 1x mega terra isn't worth much. Maybe 100 ctp to the right person.

Mass storage pods cost the most at 20k ap

This shows all the artifacts you can get from pulling artifact points and how many points they cost.

The wiki usually has most answers if you don't wanna wait for a forum response.

Thank you, so the artifact was the most expensive one in terms of ap points. I couldn't find the answer on the wiki, but you found it, thanks again. In addition, could anyone tell me how much a very massive rich metallic research planet is? Thank you.

If it's not arti then probably not a lot.
