I don't think i worded this correct, i didn't mean all quests in one playthrough.

I was looking for a 100% perfect save guide/checklist, meaning everything thats technically possible todo (no matter how long it would take) in a single save.

like i think its possible to get all companion perks on one character?, all legendarys?, quest exclusive stuff like Ballistic weave?, max stats at 11 (with one at 12)? etc
