when you spawn the shell and there is an artificial god near it,the artificial god will start to make the shell's body part disappear one by one and when the shell is gone,you can see at the bottom right corner say by the artificial god "DON'T COME BACK AGAIN"and when you made the shell become the most powerful form of itself (when it whole body start glow),and when the artificial god see the most powerful form of the shell,it will make a purple black hole and at the bottom right corner again that the artificial god say "I WON'T FAIL THIS TIME"

with the two line of the artificial god i have a theory.
in my theory,the artificial god WAS an enemy to Z'othra and they have a fight,and the artificial god DID NOT KILL Z'othra but DEFEAT Z'othra and get Z'othra's soul split into many piece by the line "I WON'T FAIL THIS TIME" meaning he had fail once or even more times trying to kill Z'othra so you can see A piece of Z'othra's soul as an item meaning there is not only one piece of Z'othra's soul there is MORE piece
that even explanation the description of the artificial god that the artificial god is slowly marching through void to find something or someone,because he know that he haven't kill Z'othra yet he is trying to find Z'othra's soul and kill it completely
(also you can't hurt the artificial god with the shell's eyes lazer)
