Listen I'm tired so ima cover a few real quick:
003:a computer chip made of har and nails and stuff
004: a wooden barn door and twelve keys the door goes to some abandoned factory
005: ever heard of a skeleton key? The term means a universal key to everything in something like a school. This can just unlock literally anything even digital locks, although disguising it as something other than a lock does tend to confuse it
006: it's just a spring that heals you when u drink from it. Like straight up regrowing limbs level regeneration.
007: it's a guy without organs and has a mini earth inside him or outside him idk it's unclear. Its continental alignment is off by a lot because it matches no known alignment in history. There a micro organisms that have the technology of around the 15th century
