Well, that sucks.Jubjub kills or causes the death of most of the world's NPCs immediately after you check a bonfire or die after reaching SP10. Any pledges linked to those NPCs is also nixed. You're probably going to need to just bite the bullet and get an ending so you can reset with NG+.
yeah Im doing blind playthrough this time, and I will replay it again once dlc3 came out with full spoiler on npcs safety
