I always thought Nerd Rage! was a pretty cool perk. It had some neat-o effects and in general sounded like a nice reward for sticking with one of the most useless skills in the game.
That is, until, I actually got it. The problem is that whenever I'm fighting weak enemies, they can't get my health anywhere near 20%. Whenever I'm fighting strong enemies, I always either take a Stimpak or get OHKed by the time my health drops that low.
What this mod does is simple. It changes the condition requirement for health percentage from 20% to 35%. That way, it's still a "clutch" perk in that it's situational, but it also doesn't require you to be completely near death; It gives you a little boost when you need it most instead of when you're right about to die.

Also, as a little bonus, I've included a version that re-adds the Cyborg perk from Fallout 3 into this mod to further help out the science skill in not being such a POS. I did change one little thing about it (Boosts fire resistance instead of Energy Weapons) but other than that, it's exactly the same.

Does not require any DLC.
