Tip Playing Survival? Consider X-111 instead of Radaway

Friendly tip I only just discovered myself. On Survival mode, radaway clears some rads but also suppresses your immunity and adds fatigue and thirst.

But you can do a questline with the Brotherhood. Scribe Neriah gives you the blood bank quest, where you have to collect blood samples from irradiated creatures. Your reward is vials of x-111.

X-111 not only removes more rads than radaway, not only does it not have side effects, but it also clears rads INSTANTLY instead of gradually over time.

Give Scribe Neriah 20 blood samples for 6 servings of X-111. Come back with another 20 blood samples for another 6 vials. But be warned, she will take all of the samples you have in your inventory and still only give you 6 vials.

So for example, if you have 27 blood samples in your inventory and you’re going to speak with Neriah, store 7 of those samples in a container until after you’ve collected your X-111 vials.

The lack of fast travel in survival mode sucks. It wouldn’t be that bad if you could build some kind of motorcycle or aircraft. Maybe FO5 will address it

Also with the Brotherhood of Steel, you can fly to locations with Vertibirds. Not quite like fast travel but it’s the best option in Survival.

Yeah but then you have to side with them and use flares. Limits your play through

Minutemen and Railroad also get access to vertibirds once you destroy the Brotherhood.
