Love it.

It's such a relief to not have to worry about radiation any longer, anywhere. Combine it with Aquagirl and I'm having a wonderful time at the Glowing Sea.

Finally! Some challenges! Deathclaws, radscorpions, mutants (even a Behemoth!) and so many places to explore and see.

Ah! I love being level 50 with these perks. I can still look hot and not have to clomp around in that stupid PA to get anything accomplished.

Sure it limits my companions to robots and synths, but, I have a question: Is Dogmeat a synth or something? He is utterly unaffected by radiation. If it's just that he's a dog, it's no wonder that dogs have basically remained the same despite all the radiation.

NPCs aren't affected by radiation like the PC is. You can wander through the Glowing Sea for days with Piper, and she'll never drop dead from radiation poisoning.

Huh! I didn't know that. I always just assumed that any human follower would have issues. Good to know.
