I'm looking to maximize artifact production on a colossal Gaia with moons- invincible, so don't bother with cloak, defense, etc...

Not the perfect build and this is only on 81 space but this is my Rift's structure list.

Trellith Comm Relay Research: 2, Artifact: 2
Hypergate Mining: 2, Research: 2, Artifact: 2
T.O. Manufacturing Core Mining: 2, Artifact: 2
Bane Generator II Mining: 3, Artifact: 3, Attack: 800
Scruuge Hoarding Vault II Artifact: 3, Artifact Storage: 5000
Scruuge Hoarding Vault II Artifact: 3, Artifact Storage: 5000
Omnistream Gateway Mining: 3, Research: 3, Artifact: 3
Hyperforge Fabricator
(100% Upgrade) Artifact: 24
Hyperforge Fabricator
(100% Upgrade) Artifact: 24
Litheor Transmutative Locator Bonus Artifact: 6%, Defense: 10%
Isolation Bureau Mining: 2, Research: 2, Artifact: 2, Cloak: 400
Cognizant Omniforge Mining: 1, Research: 1, Artifact: 1, Bonus Production: 5%
Heist Dispatch Station Mining: 2, Artifact: 2, Attack: 300, Attack: 10%

(100% Upgrade) Artifact: 24
Auric Lepus Drone 3.0 Research: 1, Artifact: 3, Attack: 1500, Defense: 1500
Auric Lepus Drone 3.0 Research: 1, Artifact: 3, Attack: 1500, Defense: 1500
Alarri Signaling Drone Mining: 1, Artifact: 1
Intraphasic Hoveroid Bonus Production: 5%
Quantum Accelerator
(100% Upgrade) Artifact: 4, Cloak: 300
Quantum Accelerator
(50% Upgrade) Artifact: 3, Cloak: 225
ArcRift Tower Bonus Artifact: 6%

Of course, you can't have an ArcRift tower and the last quantum accelerator needs to be upgraded again. Also, once you've used up your Drone signals, there's not much point in having the structure as you can replace it with something with a better space ratio, I'm sure.

Uhhh... Was there a reply in there?

Nope. I didn't even mean to post anything...

No idea what happened.
