Quest stages

20 Secure viable blood samples for Scribe Neriah.


  • Viable blood samples can be collected from various feral ghouls, mole rats, mirelurks, bloodbugs, deathclaws, feral dogs and super mutants.
  • No matter how many blood samples are given, this objective will never be removed from the Pip-Boy. To fix this, use the console to type SetObjectiveCompleted 001b2b08 20 1. This will not disable the quest; the player character can continue to secure blood samples.
  • If Ad Victoriam is failed yet the player character remains in the Brotherhood of Steel's good graces, Neriah will no longer open dialogue with the player character, although she will be cordial. The quest will remain in the Pip-Boy log but the Sole Survivor will be unable to turn in any samples.
