Are Originum slugs even edible??? They do have inert Originium after all
Iirc it's stated at one point (I wanna say during the R6S collab story) that originium is only found in the shell, the body is completely free from originium and the slugs don't contract oripathy under natural means. There's also art in one of the illustration collection books that shows slugs sitting on the counter of a food stand.
