hey sorry if im silly but didnt rose give john her strife specibus needlekind to initiate the scratch? hence why she was unarmed when travelling to 'blow up the green sun', and thats why dave had to kill DD. does she get it back at any point, or does she transcend needing it upon god tiering, or.. am i just mistaken?

She didn’t exactly give it to John, John kinda took it off her corpse. But she probably got high enough level that she didn’t need a specibus to use a weapon.
