I find companions to be buggy and annoying, so I went for Lone Wandered path. However I would still like to do companion quests. What is the easiest way to get these, keeping using companions to minimum?
Ok so I guess you want their perks. To quickly max out affinity do an action, save, reload save and do the same action again:
- Piper: Find a safe or locked door you can also unlock with a computer. Unlock the safe and relock it with the computer then save reload repeat.
- Codsworth & Curie (You can do both of them at once if they are in the same settlement after being you companion at least once): Take a piece of modified armor you find off a dead raider or so, take the mod off, save reload, put the mod back on save reload repeat. (armor is the best for this as taking a mod off the first time doesn't use any mats unlike weapons)
- Danse: Get in your power armor, get out of your power armor, save reload repeat.
- Cait: The same as Piper but I heard taking off all your clothes in a settlement and fast traveling to another settlement also works.
I really don't know about the other companions as I don't play with them. If it's really the mission you want, Piper and Codsworth don't have a mission. Curie's mission can be done immediately, Cait needs max affinity for the mission to start. I'm not sure about Danse, he's my current companion and I haven't paid attention to him or his needs.
