Affinity
Information
Content	Companions

Affinity is a companion gameplay mechanic in Fallout 4 and Fallout 76.

Background

Companions can develop personal connections to the Sole Survivor and some may ask for help with quests of their own. Each companion has a distinct personality and values. Actions or dialogue that please one companion may displease another.

Raising the affinity value grants additional dialogue into their history or the possibility of romance. Reaching maximum affinity with a companion will unlock a special perk. The affinity value is a hidden statistic, meaning it is not possible to check the progress without console commands.

Companions and allies

The following companions and allies in Fallout 4 and Fallout 76 respectively can be romanced via the affinity gameplay mechanic.

Fallout 4	Fallout 76
Cait Curie Paladin Danse John Hancock Robert MacCready Piper Wright Preston Garvey Porter Gage	Beckett Sofia Daguerre

Scale

All companions begin at an affinity value of 0. If the affinity value reaches 500, they will "admire" the Sole Survivor and often reveal new dialogue. Raising their affinity to 1000+ (max is 1100) will result in them "idolizing" the Sole Survivor, at which point the Sole Survivor is granted their companion perk.

Lowering the affinity to a sufficiently negative value will displease the companion, and they will issue a single warning to the Sole Survivor, asking them to change ways. If the affinity value drops further, they will become angry and refuse to travel with the Sole Survivor. This decision is permanent. For most companions, a new dialogue will be triggered when the affinity value reaches 250, 500, 750 and 1000.

Affinity	Relationship	Reaction
1000	Infatuation	"/Companion/ idolizes you."
750	Confidant	-
500	Admiration	"/Companion/ admires you."
250	Friend	-
0	Neutral	"/Companion/ tolerates you."
-500	Disdain	-
-1000	Hatred	"/Companion/ hates you."

Reactions

There are four different reactions a companion can have towards the player character's actions/dialogue that will affect their affinity value:

Reaction	Affinity change
"/Companion/ liked that."	+15
"/Companion/ loved that."	+35
"/Companion/ disliked that."	-15
"/Companion/ hated that."	-35

However, these values can be further modified by being multiplied by an affinity size scalar:

Size	Scalar
CA_Size_Small	0.5
CA_Size_Normal	1
CA_Size_Large	1.5

Some actions, such as modifying weapons, picking locks, and entering power armor will raise affinity with certain companions and can be repeated indefinitely. Performing a single one of these actions within a range of multiple characters who respond to said actions will trigger the respective increases or decreases with all of them. However, these responses have a cooldown period, meaning it is not possible to perform the same action several times in a row to gain/lose affinity. For example, entering power armor will trigger only one instance of approval from Paladin Danse and/or X6-88 until sufficient time has elapsed. Most repeatable actions are of type CA_Size_Small, so it will only increase the companion's affinity by 7.5 for a "like" and 17.5 for a "love".

It is possible to perform different actions back-to-back and receive two or more separate instances of approval. (For example, picking a lock and then hacking a terminal will grant two separate approvals from Deacon.) Similarly, in a conversation with an NPC, each dialogue choice counts as an action unto itself, independent of the rest of the overall dialogue, so it is possible to obtain multiple likes and loves in the same set of dialogue with the same NPC. (For example, in Order Up, the Sole Survivor can gain two likes from Piper by saying "You're both wrong" to Wolfgang, then agreeing to talk down Trudy.) For a more detailed list of what specifically pleases or displeases a companion, see the respective companion page.

Affinity can be also increased passively by simply having a companion follow the Sole Survivor. The increase depends on the current affinity level and will be lower with higher affinity values. The formula for the increase is 40 - 0.033 x affinity value. (i.e. companions with 100 Affinity will gain a 36.7 increase, companions with 250 = +31.75, 500 = +23.5, 750 = +15.25, 990 = +7) The affinity bump is awarded after every ten minute period that the companion has been following the Sole Survivor, on the condition that at least 1 XP has been earned during that time. Assuming the above conditions are met and no other actions are done to gain or lose affinity, this means it would take 520 minutes (8.67 hours) to reach 1000 affinity with a companion starting at 0; however, it would only take 160 minutes (2.67 hours) to reach 500 affinity with a companion starting at 0.

When the player character recruits a companion, the companion's affinity increases by 3%. The companion recruit counter can be reset by finishing any quest or progressing any quest to next objective, meaning that the player character can recruit all companions and increase their affinity by 3%, complete a radiant quest and then come back and recruit them again which increases their affinity by another 3%.

Romance

Certain companions are potential candidates for romance and throughout the course of their affinity based conversations, the dialogue option to "flirt" will be available. At the highest level of affinity - and final conversation - the "romance" option will be available. Both options are speech checks. Successfully flirting will reduce the difficulty of the final romance check and successfully passing that will make the companion a love interest. This will result in them addressing the Sole Survivor in a more affectionate manner (for example Preston Garvey will call you "Babe" or Danse will say "I always have time for you" when attempting to talk to him). Also, sleeping in a bed with them nearby will also grant the Lover's Embrace perk.

Companion romances are not mutually exclusive; if a new companion is romanced, previously romanced partners will still confer the benefits of the Lover's Embrace. However, some romanced partners will "hate" or "dislike" flirting in their presence, including flirting with Magnolia at the Third Rail.

Even if one fails to romance a companion, they still have chances to try this again: after a certain amount of time the companion will initiate a conversation regarding their relationship with the Sole Survivor as their best friend and from there the player character can try to romance them if they want to.

To end a romance, drop the companion's Affinity value below 750. One can make this happen by doing things they dislike or hate until they tell they want to take a break. The progress of such can be checked by selecting them with the console and then using the command getav ca_affinity.

Break-ups

For PC users, a shortcut is to use the console command setav ca_affinity. Select the companion with the console and then use the command setav ca_affinity 764. Now do something the companion dislikes, lowering the Affinity value by 15 and dropping it to 749, the maximum it can be for them to initiate the break-up dialogue. Only the action itself can initiate the dialogue, and only if it drops the Affinity value from 750+ to below 750.

To fix a romance, raise the companion's affinity value back up to 1000+. One can use setav ca_affinity 999 to get to affinity 999 and then do something the companion likes or loves to bring it over 1000.

Affinity can be set between 1030 and 1100 before doing something a companion dislikes or hates, so long as the resulting affinity value is still above 1000 after the action. The message noting they disliked or hated it will appear along with the message noting they idolize the Sole Survivor. The modav ca_affinity command breaks gain/loss multipliers and ends all future romance options. This effect also persists on saves and is irreversible without modifying the save file.

Companion perks

Those perks are acquired by reaching the maximum level of affinity with a companion. The perks obtained this way are obtained permanently, even if the affinity level later changes or if the Sole Survivor chooses another companion.

Repetitive

The following actions not only increase the affinity of the listed companions but can be repeated after an internal "cooldown" has reset.

Actions
Weapon/armor modding Codsworth and Danse love this. Gage, Preston, and X6-88 like this. (Must wait 48 in-game hours) It is easily repeated with the "None" attachment, which simply removes an existing modification and costs nothing to produce. They can all be affected by being within range of the weapon workbench simultaneously, making it much easier to raise all five companions' affinity.
Entering power armor Danse and X6-88 like this. Note that Strong dislikes this, so he should not be in the same settlement or general location while performing this.
Stealing Gage and MacCready like this. Preston and Codsworth hate this. Nick, Piper, Curie, Danse, and Hancock don't like it. It can be repeated by placing an item in a container owned by someone else and taking it back out, preferably in an area the Sole Survivor can close from prying eyes such as a hotel room in Goodneighbor (must wait 48 hours between each item stolen, or will not work). Pickpocketing Cait likes this. Preston and Codsworth hate this. Nick, Piper, Curie, Danse, Longfellow and Hancock don't like it. Works with items of any value, even a single round of .38 caliber ammunition. It can be repeated by reverse-pickpocketing the stolen item (or any item of low value and weight) back into the person's inventory. May require ranks in Pickpocket perk to boost the chances of success. Grenades are not recommended as they will act as live grenades once you reach level 2 or higher for this perk. Lockpicking Gage, Cait, Deacon, and Piper like this. MacCready likes this, but only to locks owned by others, whereas Piper dislikes picking owned locks. Strong dislikes picking any locks. This can be repeated by using a safe that has a terminal attached to it, opening the safe and then using the terminal to lock it again. Such safes can be found in: Fiddler's Green Trailer Estates Medford Memorial Hospital: Advanced lock. Mass Bay Medical Center: Novice lock, second floor across from the jail cells. Back Street Apparel: Advanced lock, on the first floor. Hubris Comics: Grognak's axe case. (Advanced lock) Greenetech Genetics: Expert lock, on the seventh floor. Super Duper Mart: Advanced lock. Ticonderoga: Expert lock, on the first floor near the exit terminal. Cambridge Polymer Labs: Up the staircase and to the left in the main lab. Fraternal Post 115: In the second-floor office on the north side. There is a Novice locked terminal and a floor safe. Diamond City: Advanced lock in the mayor's office. Cambridge Police Station: First floor to the left of the main entrance after completing Shadow of Steel. Atom Cats Garage: Novice safe in Zeke's trailer which is counted as stealing, attached to his terminal which is not. Hacking Nick, Deacon, and X6-88 like this. After an unspecified amount of time away from a map cell, it and its contents reset, including any terminals, which become "re-locked" and can be hacked again. Cannibalism Strong likes this. Cait, Curie, Piper, Nick, Danse, Deacon, Preston, and Longfellow don't like this. Requires the Cannibal perk. Murder Gage likes it and Strong loves it. Longfellow dislikes it. Everyone else except X6-88 hates it.
Using chems Hancock likes this, as does Cait prior to her companion quest. Afterward, she dislikes it. Codsworth, Danse, Deacon, Gage, Preston, Old Longfellow, and X6-88 dislike this. Addiction Hancock likes this. Cait likes it prior to her companion quest but dislikes it afterward. Everyone else dislikes when an addiction develops, except Nick, Piper, and Strong, who are indifferent. Developing an addiction is independent of the initial like/dislike from using the chem that caused it. Alcohol Cait likes consuming hard liquor before her companion quest. Afterward, she is indifferent to it. Old Longfellow likes this. Like Cait, he is indifferent to the consumption of beer. Porter Gage dislikes this.
Quests Rogue Robot Codsworth, Piper, Nick, Curie, Hancock, Strong, Deacon, Danse, and Preston like accepting quests from Isabel Cruz. Curie, Nick, Piper, Hancock like accepting quests from settlers, though only if the peaceful dialogue is used, while Preston loves this action. Cait dislikes doing quests for settlers, and Porter Gage hates this. This can be repeated and will occur if talking to the settler first, or after receiving the quest from Preston Garvey or Radio Freedom, then talking to the settler.
Brotherhood of Steel Curie and Danse like the Brotherhood. Cait, Piper, Nick, Preston, and Strong dislike working with them. Doing quests for the Brotherhood can raise affinity but only for those in your party who are neutral towards that faction. Minutemen Codsworth, MacCready, Danse, and Piper like the Minutemen and like working with them. Cait dislikes them. The Railroad Piper likes the Railroad and their plan. Cait and Curie don't like them. The Institute X6-88 likes doing quests for the Institute. Everyone else dislikes siding with the Institute and Danse hates them.
Misc Cait and Hancock like this, regardless of the player character's sex. Longfellow does not like this. Triggers by transitioning between two areas (indoor or outdoor) while not wearing any clothing underneath armor; this includes hats, bandanas, eyewear, military fatigues, army fatigues or vault jumpsuits. The player character can still wear arm guards, leg guards, chest pieces, and the wedding ring. A fast way to do this is to buy the Home Plate house in Diamond City for 2,000 caps. Place a bed in front of the door, sleep for two hours, then exit to Diamond City and re-enter Home Plate. Rinse and repeat as necessary. (Note that this gives 7.5 affinity for Hancock, not the expected 15) Another way is to find two areas with chairs the Sole Survivor can wait in and a door separating them into two different maps. 'Wait' for 2 hours in one, go through the door and wait 2 hours in the other, and go back through the door. Rinse and repeat as necessary. Approval triggers once on each pass through the door. A good example is a couch in Publick Occurrences and the couch against the wall of the barber stand outside. Everyone except Strong, X6-88 and MacCready like this. Repeating this will likely require deliberately wounding Dogmeat in a settlement with the character(s) in question nearby, as the Sole Survivor can only have one companion out at a time. Settlers will attack if the Sole Survivor attacks Dogmeat, so be sure to bring him to an area with no settlers. Dogmeat can be wounded by falling damage which can easily be caused in workshop mode, by building several stairs that can then be selected or deleted from under him.

Notes

• Paladin Danse, Curie, Cait, and Nick Valentine cannot reach max affinity until their respective personal quests have been completed.
• Robert MacCready's quest cannot continue until an affinity level of 750 is reached.
• Affinity will stall if the appropriate dialogue has not been activated yet. When they've reached a tier limit - no actions are counted towards positive affinity, but the messages of approval still appear. For example, MacCready and Curie will stay at 499 until the player character helps complete their respective quests, Cait will stay at 999 until her quest is completed (romance dialogue appears at 1000 affinity), Danse stays at 999, until the Blind Betrayal quest is completed.
• Preston Garvey's affinity will instantly drop to "Hated" if you take over a settlement for raiders during Home Sweet Home.
• It is not necessary to romance companions to gain the respective perks for reaching maximum affinity. This just enables the Lover's Embrace perk.
