Job Role:
Harvest the corpse of those who died of everything excluding Bones and Flesh to sell on the dark web to make a profit or two, cremate the remains after it's been harvested to then scatter around the arena to add more dust effects, the tradition has since then been discontinued and the dead bodies were since then sent down a lava pit below the facility
(To simplify the job role has the worker open up the dead bodies to harvest anything that isn't bones and disposing the things that aren't intestances, organs, ect, idk how this would work on clones but I guess if it's in perfect condition it can be resold unless it starts decomposing immediately after the clones death then I guess they have to dispose of it)
