For players looking to get an edge in Fallout 4 so they can tackle some of the more difficult missions, they should consider earning one or more of the Companion perks available in the game. These perks give the Sole Survivor some kind of bonus, depending on the companion's skills, personality, and backstory.

RELATED: The Best Perks Every Player Should Get In Fallout 4

All companion perks in Fallout 4 are earned by achieving maximum affinity with a particular companion, and each one is unique. The player should talk to their companion once the game indicates that that companion "idolizes you" to unlock the perk. Once the Sole Survivor has earned their perk, it's permanent; they can't lose it even if the affinity level with that companion changes or they have another companion follow them.


Keeping Track of Affinity

Unfortunately, a companion's affinity level is hidden from the player and can only be seen through console commands. However, there are a few tools that can be used to keep track too. Usually, companions will begin with an affinity level of zero. The maximum possible affinity is 1000 points, and the lowest possible is -1000 points.

If the player isn't sure where they sit on the Companion's affinity scale, they can work towards earning affinity and wait for the game to let them know when they've hit a major milestone.

-1000 Affinity: Hatred

  • The game says that the Companion "hates you"

-500 Affinity: Disdain

0 Affinity: Neutral

  • The game says that the Companion "tolerates you"

250 Affinity: Friend

500 Affinity: Admiration

  • The game says that the Companion "admires you"

750 Affinity: Confidant

1000 Affinity: Infatuation

  • The game says that the Companion "idolizes you"

When players know how much affinity they need to get, they can keep track of said affinity through the Companion's reactions to what the Sole Survivor says or does.

  • The game indicates the Companion "liked that": +15 Affinity
  • The game indicates the Companion "loved that": +35 Affinity
  • The game indicates the Companion "disliked that": -15 Affinity
  • The game indicates the Companion "hated that": -35 Affinity

Console Commands

If the player can use console commands, they can use the "GetAV CA_Affinity" command to check and see where their Companion's affinity is at. Players can also use console commands to raise, lower, or reset a Companion's affinity, but should be cautious — some console commands can permanently affect or change the player's save file.

Accruing Affinity

Fallout 4 One Punch Power Fist

The player can earn affinity with different characters by performing actions or choosing dialogue options that they agree with. Every action or dialogue line, big or small, could have an effect on the companion's opinion of the Sole Survivor.

A few things to keep in mind...

  • Romance: Flirting with the Companion will help increase their affinity, and the player can romance more than one Companion at a time
  • Speech: Having a high speech skill may help the player flirt, get out of awkward situations, and more
  • Dialogue: Each dialogue option counts as its own action, so each option over the course of a conversation can provide affinity points
  • Cooldown: Some actions are "repeatable," so they'll earn affinity points every time the player does them (like healing Dogmeat, drinking alcohol, hacking, murder, lockpicking, and more), but they have cooldown periods, so they can't be repeated over and over again in one go
  • Modifiers: When a player receives or loses affinity points, the game may assign a modifier to it, meaning, for example, when a Companion "liked" a player's actions, it may be slightly more or slightly less than +15 affinity — but it's a good estimate if the player can't use console commands
