      Fun fact: In NG+ you can keep using regen extension factors. It won't increase your maximum. But it does restore a spent use of regeneration. So without passives you can have 13 uses of regeneration.

        Had ten, Now I have eight. No idea why I lost them. Be nice to know why the game is punishing you. But it looks like it is just the drunk abusive father you would rather not live with.

          I've been all around these places, and again after 100% to look for the items. They just aren't there for me. I see the white area where they spawn, but nothing. Only got one so far. Bit weird.
