Just an idea that Pm4000 from the same legion I'm in came up with.
However i'm somewhat improving upon it.

Artifact: Planet Collider
Effect: Opens up a gravitational rift in which 2 planets, 1 Ice and 1 Volcanic collide into each other to form a new planet, which over extensive time manipulation creates a decent Terra like planet. Also requires an Ice and Volcanic planet in order for use. Requires 50 energy to use.
Resource stats: Mining - Mega Rich to 10x Mega Rich (High due to denser core from two planets creating more and precious metals)
Artifacts - Mega Rich
Research - Mega Rich to 5x Mega Rich (High due to the need to study the effects of colliding 2 planets and extensive use of time manipulation)
Received from: Mission
Note: The name could be called something like "Terrus" or "Medietas" as it was made rather than occuring naturaly
"Terrus" is a Latin translation of Earth according to google.
"Medietas" is a Latin translation of Mid out of "Midgard" according to google.

Idea for the mission

Appears at level: 100
(Your Race) Government: (Your Race), our top scientist are working on a new project. The object of this project is to create a Terra planet. Since i am not a scientist i do not know the exact details on how this will be achieved. From what i was told they need you to do these tasks. After the task are completed they will reward you with a new device for field testing.
Requires:
75 Energy per attempt
Researched "Micro-Singularities"
250 Exotic Matter
1 Planetary Time Vortex

50 Attempts to completion
10 Rounds to completion

Xp: 3* energy return rate (225 xp) (Reason is because it requires alot so it's only fair)

Reward: Planet Collider

Well what do you guys think?

i like it! the only suggestion i would have is a name change instead of unnatural terra. I would suggest Midgard, to keep the tradition of the viking creation myth when Muspellheim (the land of fire) and Jotunheim (the land of ice) first met and sparked life and the world of man, Midgard. The planet would look like a terra around the mid 1/3 of the planet, a volcanic around the top 1/3 cap and an ice around the bottom 1/3 cap. the name would change to Midgard I and would continue such as the vorigar planets do in the order they are created.

These changes are all cosmetic tho, i really like the idea of making terras! spacewise tho, would it be the size of the maximum planet used, an average of the two planets used, or the two planet sizes combined, or just a +1 or +2 to the largest planet used?

Well since ice expands, the core, mantel and crust of an ice planet wouldn't be that large and since a volcanic would be basicaly all rock and magma, i would say either a +1 or +2 to the largest of the two planets sacrificed.

nice. i like that. it would give us the chance to make another type of megacollosal.

I guess anything above mega collosus would become a star lol

I suggest having it related to the two planets used to create it:

Now when colliding planets, there will be some loss. But if the planets are large enough this won't matter. So I suggest size1+size2-3size=New size. So an average(5) and an average(5) would make Colossal but minus 3 so Very Large(7). Very Large(7)+Very Large(7) is the minimum to create Mega Colossal(11). Without the loss all it would take to make Mega Colossal would be Large and Average, which isn't reasonable. Resources would be like this:

Combined mining-10%(Again, loss) so a Mega Rich(12) and a average(4) would make a 4xMega Rich-1.6 rounded down(Always) to 1 so 3x Mega Rich. If the percentage is below one round up.

Research would be a random amount from Mega Rich to 15x Mega Rich.

Artifacts would be the combined artifacts+rand% from 5-20(time manipulation). So a Abundant(5) and a Ultra Rich(11) with 10% added would make 4x Mega Rich+1.6 rounded down to 1 so 5x Mega Rich artifact. If the percentage is below one it rounds to the nearest whole. So if the combined artifact was Very Rich(9) and the percentage added was 5% the percentage would be .45 which would mean 0 added. If it was Extremely Rich(10) it would be .5 so rounded up to 1.

So if you were aiming for mining you wouldn't do this but instead colonize both separately, because of the loss in mining. You would mainly do this for the size and research/artifacts. And also to take up only one planet slot instead of two.

Good points
Maybe the loss could be more severe the larger the two planet are?
Plus the benifit would be if you use 2 crap planets and instantly get good resources it would be very handy plus giving you room to colonize another planet.

+1

i like this idea, it would help those who have a ton of volcanic and ice planets that are of various sizes but less than satisfactory resource production

and in doing so, it would free up their planet scan page and allow the player to scan for more planets.

Kudos to you

Kudos to Pm4000 aswell since it was his idea and i basically just improved and upgraded it lol

Kudos to Pm4000 too

Hehe

Do I have the math right? 500 PTVs?

+1

Yeah i guess that's right, but atleast they're alot more common than Terraforming Devices lol

Funny my friend asked me yesterday what would it be like if we merged planets like if you merged a desert and ice it forms a terra becouse the ice melts and the water brings life idk thought id share cool idea by the way
