Fallout 4 All Companion Perks Complete List And How To Unlock Them

Exploring the post-apocalyptic Commonwealth becomes significantly easier when you travel with trusted allies by your side. These unique characters offer deep narrative storylines alongside valuable passive combat and survival modifiers. Understanding how to earn these status upgrades transforms your character into the ultimate wasteland survivor.
How to Earn Maximum Companion Affinity
Unlocking a companion perk requires raising your relationship level to the absolute maximum value. You can increase this hidden metric by performing actions that your current ally approves of during exploration. For instance, certain partners favor altruistic choices while others prefer locked terminals being hacked or locks being picked.
Once you reach the highest tier of friendship, the character will initiate a final personal conversation. Successfully completing this dialogue sequence permanently rewards you with their unique passive bonus. These specialized traits remain active for the rest of your playthrough even if you choose to dismiss the companion later.
Combat and Survival Bonuses From Core Allies
Several standard followers provide excellent defensive capabilities that keep you alive during intense firefights. For example, the robot Codsworth grants the Robot Sympathy bonus, which increases your damage resistance against energy weapons. Similarly, the synthetic detective Nick Valentine provides Close to Metal, allowing an extra guess when hacking terminals.
If you prefer an aggressive approach, travel with the brawler Cait to receive her specialized Trigger Rush capability. This ability accelerates your overall Action Point regeneration whenever your health drops below a certain threshold. Earning these benefits significantly improves your general efficiency when dealing with dangerous raider camps or mutant strongholds.
Medical assistance is another vital aspect of surviving the harsh radioactive environment of Boston. The companion Curie offers the Combat Medic perk, which automatically heals a massive amount of health if your life bar falls too low. This automated healing capability acts as a perfect safety net during unexpected encounters with apex predators.
Advanced Strategic Perks for Specialized Builds
Players who favor stealth mechanics will find tremendous value in partnering with the analytical reporter Piper. Her Gift of Gab perk doubles the experience points you receive when discovering new locations or passing speech checks. This bonus allows tactical players to level up their core attributes much faster in the early stages of exploration.
Alternatively, executing stealth operations with Deacon grants the Cloak and Dagger status modifier. This modifier heavily increases your sneak attack damage while providing a massive boost to the duration of your Stealth Boy items. Selecting the right partner ensures your active bonuses perfectly match your preferred playstyle in the Commonwealth.
For players focused on maximizing raw ballistic damage, Paladin Danse provides the perfect military endorsement. His Know Your Enemy perk grants a permanent damage boost against gouts of super mutants, ghouls, and synths. This offensive modifier represents an essential addition for anyone planning to clear out high-level strongholds across the southern map borders.
