"Nefer's personal quest... unlocks after completing all four related quests"—well, please state in the article that, like Yagoda's quest, it doesn't unlock without a character. Otherwise, it sounds like there are no other requirements.
What to do with the remaining intelligence? 4 pieces.
I have 0 intel. How do I get it?
See the section "Where to get recorded intelligence".
The quest "The Man Who Once Lied" (Nefer's personal quest) is only available if you have Nefer on your account (without her, it says "Nefer Needs Knowledge" and won't let you accept the quest).
The developers certainly came up with a cool idea. I don't have Nefer, so I started collecting this data only with the Berry drop. It's nonsense, I thought. Well, a few missing quests won't really ruin things for players who don't have these two characters.
Today I stumbled upon Dabit, collected the data, and completed the automatic quest, but suddenly the "End of an Innocent Age" achievement popped up. Great developers! Bravo! So, did those who skipped Nefer and didn't spin Durin's banner get a lip-smacking achievement?
With Nefer/Yagoda the achievement is simply earned faster—right away instead of 7 weeks (or 9, I forgot)
I picked it up myself without Nefer and before Yagoda's release
Can you tell me how? All the websites say it has to be Nefer or Yagoda.
Buy investment tickets from Dabit and exchange one per week for a bag of Mora. Once you've exchanged everything, a quest will automatically be given, and upon completion, you'll receive an achievement. This is exactly how I got it without Nefer, even before Yagoda's release.
