if something isn't Send, then it's a cursed item you can't give away, it's yours to deal with
if something isn't Sync, then it won't even appear for other people, it's possibly an apparition inside your head
things that are Clone can reproduce asexually, but only on command. things that are Copy won't bother waiting for you
