ok, so according to the wiki this turns a planet into a Massive Exotic with 13x Megarich in everything. does this mean if i use it on a very tiny very sparse barren planet that it will be converted? or will it be a very tiny exotic with 13x megarich?

it will become a massive.

It becomes a massive 13x mega rich no matter the planet. This artifact requires the use of 10 seperate terraformers though and can only be gained once through a mission unlocked at rank 50(I think).

the mission requires 10 turns to complete which gives you a hyper terraformer however for every turn you complete, you have a chance of getting a hyper terraformer

and what mission would that be?

It's called "The Terra Project". 10 steps to complete, need to turn in a normal terraformer for each step. Takes a while. I've only found 3 so far, no bonus Hypers.

make sure the planet you use it on has not been scanned by any other ships, or you me be in for a big surprise....

Since we've really only got one chance to get it right, this is my own plan for using it. Find an unscanned volcanic rock, use 7 eruption channelers on it first, and make sure I have Cloaking Satellite tech ready at the minimum.

That's my plan too, but I'm thinking of using it on a planet with a Volcanic heat Seeker, hoping the effect will still be doubled.

First time I heard this... Corroborating evidence?

I'm thinking of using a very massive, filling it up and when its size gets reduced, everything should still be on it...

The mission description says it's possible if you read it closely.

huh... never really read the description that way, but i guess so... silly me

although according to the wiki, there is only 1 available. Would be pretty sweet to hit it on the first try...

wait, the planet keeps the passive effects that were already on it? like eruption channelers?

Yes, unless they decide to change that, but hopefully they won't.

ok, cool. good to know.
