This will grant you heavy resistance against fire, electro, chem, phys and grant you massive sprint endurance only leaving psi open. This will only require you getting a cheap vest with 5 slots and two of which being leads and you are fit for money grabbing

Buying lead containers will give your artifact slots a Green line below. Any artifact places there will NOT generate any radiation at ALL. So with the liquid rock in a not greened slot and having 2 lead container upgrades, you can use 3 maximum rad artifacts while being rad neutral, while having the 5th slot for your own use with anything NOT generating rad at all. This is an extremely heavy gain. Especially when using thunderberry, hypercube and compass together.

I found a rare weight artifact called "Night Star" not listed here

As far as I can tell the "Petal artifact" pretty much doesn't exist at this point. Can we get that added to the list? (Don't have a photo on account of it may or may not existing)
