Fallout: The Traveler/Companions

Returning from the previous games, now combined with elements from the popular Fallout New Vegas mod JIP Companions Command and Control. The Outer Worlds and the Character system from Genshin Impact albeit cut down. Companions played a much bigger role in Fallout The Traveler. They can be found all over the wasteland and depending on the reputation on the faction you are, your profession given at the start, all has Paimon Pip entry, equipable with a specific Weapon, skills that are skilled at, and belong to both Wanderlusters (independents) and Faction aligned. On normal gameplay, they're all essential, so they cannot die unless if playing on Sawyer Mode or Immersion Mode.

How to Obtain
Companions are primarily obtained by exploring around the Wasteland and depending when you have good reputation with that faction, your profession given at the start and your karma standing. There are two types of Companions: Wanderluster and Faction Affilated. Wanderluster companions can be recruited regardless of reputation or Karma and Faction affilated companions are can be only recruited if the Traveler has positive reputation with that faction.

The Companion Ledger
The Companion Ledger at Paimon Pip shows you everything you need to know about your companions. You can see their skills, stats, status effects, perks, and gear. In conjunction with gear, you can select and swap the compatible weapon and armor for your companion. On top of that, players can also change the companion's behavior in combat such as their distance, preferred weapon, and aggressiveness.

Focus Fire
Select your companion and press the up button on the controller's D-pad once to order your companions to attack on V.A.T.S.

Companion Ability
Each Companion also has an ability tied to their Vision they can use on command. Upon activating an ability time will slow, similar to V.A.T.S, as the Traveler commands them where and/or who to fire their ability, upon command a cinematic will play showing the Companion using their ability.

Companion ability ranges from support to direct damage, but all of their ability will inflict an elemental effect, depending on their Vision, which the Traveler can combo to create an elemental reaction.

Once a bond/romance is formed the Companion will unlock their Burst, powerful abailities that can turnthe tide of battle but have a longer cooldown.

Companion Wheel
Returning from New Vegas, the Companion wheel provides easier control over the non-player character companions in the game by setting the AI and other management options.

Affinity
Companions can develop personal connections to the Traveler and most of it 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.

Bonds/Romance
Once their affinity is maxed, and their personal quest completed, the Traveler can form a Bond with said Companion. Once a bond is forged the Traveler gains a Companion Perk, said Companions stat is boosted, and their Vision Burst ability is unlocked.

All Companions can become Bonded. And most, but not all, Companions can also be romanced, which is similar to a Bond mechanically (the only difference is a romanced character and the Traveler have intimate talks and/or flirting).

NOTE: While romancing all romanceable companions is possible, only some Companions are fine with polygamy/may only be fine with polygamy with a specific Companion. Beware of consequences, especially for those who are monogamous, when they find out you're a two-timer.

Leveling
Characters gain experience primarily in combat.
