Nerd Rage!

Nerd Rage! is a Fallout 3, Fallout: New Vegas and Fallout 4 perk.

Fallout 3
Whenever your Hit Points drop to 20% or below, your Strength is raised to 10 and you gain 50% to damage resistance. This stacks with other perks, and applies regardless of clothing, which makes it still useful even if you wear heavy armor, as it can help maintain your DR even if said armor is damaged or broken.

Fallout: New Vegas
Whenever your health drops to 20% or below, your Strength is raised to 10 and your Damage Threshold is boosted by 15. As in Fallout 3, this effect stacks with similar bonuses, and applies even if you're naked or your armor is broken; you merely need to meet the health threshold.

Notably, the Courier's base health determines the trigger for this perk. Bonus HP from other sources such as Buffout or the Thought You Died perk will not raise the threshold.

Fallout 4
Note that unlike previous versions of Nerd Rage, due to the diminishing returns of Damage Resistance in Fallout 4, one should no longer consider the primary benefit of Nerd Rage to be the additional damage reduction, although it does help in a pinch. Instead, the slow-time effect is the primary defensive (and offensive) mechanism, lasting about as long as a normal (unmodified by Chemist) dose of Jet.


 * The effect does not last as long as you are below 20%, in a break with previous versions of the perk.
 * It is possible to repeatedly re-trigger the effect by healing yourself above 20% and then taking enough damage to drop back down below 20% health.
 * If time is already slowed from a Jet-based drug, then you won't get much extra benefit from the slowed time, though you still gain the damage and damage resistance bonuses.
 * There can be buggy interactions with if this perk triggers during VATS (giving you the bonus damage and resistance but not the slow-time effect), though re-entering and leaving VATS tends to help.

Bugs

 * In Fallout 4 Nerd Rage may stop activating when health drops below 20%. This issue can be temporarily remedied by bringing up the Pip-boy then closing it while your health is under 20%. It is not currently known what causes the issue. (Bug is confirmed to occur with ranks 2 and 3 of Nerd Rage. This may be a problem with ranks above rank 1. More testing is required to validate this theory).
 * In Fallout 4, the slowing of time may sometimes be cancelled by chems such as Jet. It sometimes also happens with V.A.T.S, giving you real time speed in V.A.T.S.

Behind the scenes

 * The perk is based on Adrenaline Rush, a perk which had first appeared in Fallout 2. The art is also borrowed from Adrenaline Rush, save for a few thematic changes.
 * The Vault Boy image is a reference to the Incredible Hulk, whose clothes become shredded during his transformation.
