There are a few in the shops, I just wanted to know where it originated from before I start diving into trying to acquire one. :3
To be clear, I am asking where it was stocked, as opposed to where the reference/item inspiration came from. :3
if you're ever curious about where an item comes from, you can look it up on subetalodge. you can also see by the allruin's rarity that it's a collection item, so it would just be a matter of figuring out which collection it came from.
