The Artifact Recombobulator™

[Camnui]

Think of it as similar to how you can build musical instruments, except stranger. Like using the same items but in a different order can create an entirely different artifact. Or maybe exposing the component pieces individually to stimuli like heat, cold, radiation, and what not changes them to another component piece of a different type

Better randomize what each reaction causes them to change into from round to round to stop people from building singularity bombs every round.
